From Romans to Roses - Some reflections
during a walk round the city
off the beaten track (Gerald Bettridge)
En savoir
plus…
Lyon
is a city that has a deserved reputation for secrecy. We shall go along
little known paths to search out what makes the city what it is, with
reflections on ancient and modern history along the way - on building
materials, water supplies and drains, fortifications, writers. We shall
mention the local variety of boules, so much more serious than "pétanque",
and the Urban Trail, a sort of marathon only 36km long, but also 3km up
and down!

Is Lyon a fine candidate for the title of
world capital city of roses? (Stéphane Crozat)
En savoir
plus…
The
region of Lyon was one of the main European centers for horticultural
breeding during the 19th century, and at the beginning of the 20th.
Thousands of flowers, fruits or vegetables varieties were created
between 1830 and 1960, ranging from new potatoes through to new
orchids. This remarkable context, stemming from geographical,
historical and botanical local specificities, allowed the development
of outstanding characters, such as the Guillot and Pernet- Ducher
families, still considered as uncommon breeders. Within the field of
roses, Lyon’s horticulture made a notable name for itself, since about
60% of the world varieties as of 1850 had been created in this region.
This historical insight is based on the scientific work of Stéphane
Crozat for the National Center For Research and Science (CNRS) from
2003 to 2008 and later, for the Centre de Ressources de Botanique
Appliquée
(CRBA), in Lyon. Based on historical documents from the 16th century to
nowdays you will discover how and why the city of Lyon and the close
suburbs held the leed for horticultural works. It will provide answers
to the question: "Is Lyon a fine candidate for the title of world
capital city of roses?"

Claude Ducher, Joseph Pernet-Ducher, two
emblematic rose breeders (Fabien Ducher, Etienne Bouret)
En savoir
plus…
At the end of the 19th century Lyon
was called the capital of roses.
In 1845, Claude Ducher organized the first exhibition dedicated to
roses in Lyon at Palais Saint Pierre. He went on to establish his
permanent nursery in Lyon in this wonderful area which was the birth
place of many great rosarians creating some of the world’s most
gorgeous and coveted roses.
Claude Ducher’s artistry and craftsmanship remained very important in
the world of hybridizing roses. His research and resulting creations
brought significant progress in the evolution of roses. So many great
varieties, such as ‘Rêve d’Or’, ‘Gloire de Ducher’, ‘Mlle Cécile
Brunner’ and many others are still appreciated by worldwide collectors.
Later on, his son in law, Joseph Pernet Ducher, added to his legacy in
creating yellow, orange colored roses.
In the modern era, Etienne Bouret, famous photographer and rose expert
and Fabien Ducher, rose breeder who is the 6th generation of the Ducher
Family, are going to introduce you this incredible story…

Two centuries of roses: the Guillot
creations (Jean-Pierre Guillot)
En
savoir plus…
In
the 19th century in Lyon, the Guillot family played a huge part in the
field of rose development and then in the fame of the city.
Jean Baptiste Guillot Father settled down in Lyon in 1829 and will be
one of the first along with Plantier to develop the culture f rose in
Lyon.
In 1849, the invention by Jean Baptiste Guillot Father of the technique
of budding on wild roses will make the rose culture economically
profitable and will enable its development. In 1842, Jean Baptiste
Guillot Father created the rose called 'Lamartine'. This was the first
of a wide range of creations such as the rose 'La France' created in
1867 which was the first hybrid tea rose. In 1875 with seeds coming
from Japan and after many tests of crossings, Jean Baptiste Guillot Son
obtained the first Polyantha rose bush named 'Paquerette'.
The Guillot family took a unique place in the world of rose culture
thanks to many creations realized until 2011, when Jean-Pierre Guillot,
who had no heirs, sold his company to a specialized society which
exists today under the name Roseraie Guillot. The resumption in 2011 of
this illustrious mark imposed the implementation of an ambitious
program so that the GUILLOT company can approach the 21st century on a
renewed dynamics. Multiple investments were realized to redefine the
orientations of the research, modernize the production tool and finally
expend a marketing strategy fitted to the evolution of the market.

Mallerin, the prince of color (Robert et
Marion Laperrière)
En savoir
plus…
The
first creations of Charles Mallerin appeared in 1925. He then abandoned
his engineering career and devoted himself to his passion. He was the
breeder of many varieties, roses full of elegant flowers with delicate
or bright colours.
Charles
Mallerin is a very important link in the unbroken succession of rose
growers-breeders of Lyon and its region, who, from the early years of
the 19th century until today are enriching, by their researches, the Rosa
type.
He was more an artist than a true professional, because only the colour
and the shape of the flowers mattered to him. His influence is still
present today, because among the current varieties, some are enhanced
by a distant connection with Mallerin’s roses.

Remarkable Rose Gardens in Australia
(Kelvin Trimper)
En savoir
plus…
Australia’s
vast land varies from a tropical climate in the north to cool in the
southern region. The majority of southern Australia has a Mediterranean
climate - cool to cold, wet winters, mild and damp in spring and autumn
with hot, dry summers - ideal for rose growing.
Australia does not
have any native roses. When European settlers arrived 200 years
ago they tried to re-create the gardens associated with their
homelands. Some plants, with supplementary water, including roses,
performed well and remain very popular. This illustrated presentation
will feature some of Australia’s most beautiful gardens, both public
and private.

Rose Gardens in Germany (Hans-Peter
Mühlbach)
En
savoir plus…
From the numerous rose gardens in
Germany, which are worth to pay a visit to, only very few can be shown
here in detail. Rosarium Sangerhausen,
opened in 1903, represents the world largest collection of roses and is
a place of reference for rose specialists from all over the world. In
1914 Rosengarten Zweibrücken opened its doors for visitors, who
enjoyed since then the impressive rose collection. In 1934 the Rosarium
Uetersen
was founded in the North of Germany by the joint activities of two
famous rose breeders, Matthias Tantau (sen.) and Wilhelm Kordes II. The
German Rosarium at Dortmund was founded more
recently in 1972.
Its collection of 3,000 rose varieties is enclosed in a municipal
park area. Beside these major rose gardens, some less known gardens
merit to be mentioned due to their architectural and historical
importance or due to their lovely arrangement of wonderful roses.

Abbey Valsaintes is perched on the
Haute-Provence Lavender oppidum
at an altitude of 600 m. In 1996, Jean-Yves Meignen undertook the
transformation of dry stone terraces of the abbey into a garden of
roses and plants with some 500 varieties of rose over the years.
He learned about the harshness of the climate where summers are dry and
winters harsh. Cultivation methods are appropriate and environmentally
friendly. Wild companion plants or those well suited to the climate are
also included in the garden. Nursery roses began in 1998 with a
multiplication by cuttings of old and contemporary varieties.

The Heritage Rose District of New York
City (Stephen Scanniello)
En

The
Heritage Rose District of New York City was inaugurated in Harlem (a
neighborhood at the northern end of Manhattan) on October 24, 2009
as a partnership between the Heritage Rose Foundation and the office of
Scott Stringer, Borough President of Manhattan. Since 2009, more than
1500 heritage roses have been planted in Harlem’s community
gardens, parks, universities, churchyards, historic sites, and cultural
institutions. Today antique roses flourish in over thirty-two locations
including: Trinity Church Cemetery and Mausoleum (a historic
garden-style cemetery created in 1842), the Church of the Intercession,
the Morris-Jumel Mansion, and on the grounds of Alexander Hamilton’s
historic home The Grange.
All of
the roses planted pre-date 1920 and have been donated by nurseries,
universities, botanic gardens, and private collectors.
The project is especially created for the children of Harlem. Every
year the Heritage Rose Foundation sponsors workshops for the children
on pruning, planting, and propagation of roses from cuttings.
Stephen Scanniello is responsible for making this wonderful project
happen. At the Lyon conference Mr. Scanniello will describe how
this project began, share with us stories of the original gardens of
Harlem, and share with us the accomplishments of the youngest
generation of rose gardeners in Harlem.

The impact of plant collections on urban
development (Laure Guillemette)
En savoir

The
first public garden in Nantes, the Jardin des Apothicaires was created
by Louis XIV in 1688. Soon after, Nantes became France’s principal
port and the landing point for countless shipments of plants from all
over the world such as the first Magnolia grandiflora
introduced in Europe in 1711. Nantes is also known for the first
Camellia japonica grown from seed in 1806. Now, a few centuries later,
Nantes is home to plant collections, to 100 public gardens (parks
or squares)…
Since 1971, the city has been one of the consistent front-runners in
the Villes et Villages Fleuris,
a National horticultural competition. Nantes was also chosen as the
European Green Capital in 2013. The Parc floral de la Beaujoire created
in 1971 has a very special place in the horticultural heritage of
Nantes with the National Magnolia collection and its Rose Garden
created in 1988. This Rose Garden shows the renowned know-how, to which
breeders, growers, gardeners… have contributed in order to promote the
rose.
Gardens have primarily been
valued in terms of their aesthetic beauty, ideal for pondering. In the
seventies, accompanying a fast forward motion of urbanization, public
gardens (or green spaces"
as they were referred to), were often constructed as ornaments.
Nowadays, as cities become denser, the inhabitants want more than
ornamentation. Gardens are and will increasingly be used as places of
well-being, exchanges, living space and extension of the home. Visits
to public gardens have also been seen to grow steadily with an increase
in the number of events and activities held.
For the last few years, with the tourist development, the patrimonial
wealth of Nantes has enjoyed an important promotion by which parks and
gardens have become leading attractions. So, visitors are able to
discover many unusual works, allying Happiness, Nature and Culture and
emphasizing a unique plant heritage, through its shows or events such
as The International Perfumed Rose Biennial…

The Earth-Kind®
Rose Research and Outreach Program: An International Model for the
Identification and Promotion of Regionally-Adapted Landscape Roses.
(David Zlesac, Maria Eva Giogioni and Allison Watkins)
En savoir plus…
Environmentally-conscious
gardeners increasingly seek well-adapted roses that support
environmental stewardship. Multi-year, replicated Earth-Kind®
rose trials are managed under low-input conditions throughout
geographical regions. Cultivars with superior performance are
designated as regional Earth-Kind® roses. Earth-Kind®
roses offer consumers and industry confidence that they can be
successful with these roses in their region given basic plant care. The
success of the scientifically sound, university-directed Earth-Kind®
rose program is only possible through the collaboration of multiple
stakeholders including: rose societies, scientists, nurseries, and
public gardens. The Earth-Kind® model can help rose
societies strategically partner with other stakeholders to spur on
regionally-relevant rose research.

Roses & images: a tool for
image-based rose recognition (Mihaela Scuturici)
En savoir
plus…
Experts
have a number of criteria that they use for recognizing rose varieties.
But these criteria are not available for everyone and their handling
may be difficult for non-specialists. The idea is to explore the
benefits of automatic image analysis for identifying roses. We propose
an application connected to a database containing various information
(images, numerical and text values) on different varieties of roses.
The ultimate goal is to allow query by image: the user will be able, by
submitting the photo of a flower to get in return the most likely
variety of the rose.

Overview: Rose research in France (Pascal
Heitzler)
En savoir
plus…
Despite
considerable biodiversity, roses remain a difficult material to explore
at scientific level, but nevertheless stir up increasing enthusiasm
among researchers worldwide. In France, where many historical and
prominent garden lines were created, research is a quite busy field, if
not a leading one within the world community. The most salient topics
are explored in the domain of horticulture: remontancy, floral
architecture (doubleness), perfume, floribundity and architecture,
physiology and metabolism of growth, polyploidization mechanisms,
genetics and genomics. The French community also leads an international
programme for the complete sequencing of the rose genome that will open
considerable perspectives.

Genetic model and patrimonial redundancy
(Pascal Heitzler)
En savoir
plus…
Despite
long-range breeding tradition in Europe, the rose remains poorly
investigated at the level of formal genetics. In particular, a genetic
model is missing that uses the advantages of reliable advanced wild
type pedigree and natural variants from European species. In 1997, I
started to develop inbreeding wild lines using the diploid species Rosa
arvensis
as a base for extensive gene introgression from the historic rose
cultivars. More than 80 distinct and individual traits were
considered.
This work will
constitute an index list for genes and alleles that define the
horticultural traits and variations found in roses. The deduced genetic
redundancy will help to reset the patrimonial biodiversity.

Rose genomics and perspectives (Mohammed
Bendahmane)
En
savoir plus…
During
the past decade the deciphering of the genome of many plant species
have provided scientists with a framework to understand how plants grow
and interact with their environment.
In the frame of an international scientific consortium, we initiated
the determination of the genome sequence of the rose. Such information
is expected to facilitate and speed up scientific research to
understand the molecular and genetic mechanisms underlying important
traits in Rosa (flowers, plant architecture, disease resistance, etc.).
Rose breeding is time consuming, especially for complex traits, and the
outcomes are usually unpredictable. The gained knowledge will also help
predicting plant characters through DNA sampling and tests (DNA
marker-assisted breeding) and therefore to substantially improve
breeding. The importance of a rose genome sequence and its potential
uses for the rose and for other related species, will be discussed.

Mechanisms of polyploidization (Benjamin
Govetto, Manuel Le Bris)
En savoir
plus…
Polyploidy
(more than 2 sets of chromosomes per cell) is very common in
plants, often associated with evolutionary key innovations by genomic
remodelling. The main pathway of polyploidization involves a
fertilization with diplogametes (2n gametes, unreduced gametes).
Cytologically, these gametes may result from different meiotic
modifications, all dependent on both developmental, environmental and
genetic cues. In spite of the evolutionary importance of
polyploidization and the potential to design tools and develop
techniques in crop breeding, the mechanisms of diplogamete formation
are still uncompletely elucidated. In this research field, Rosa
represents an original biological model to explore polyploidization
mechanisms.

Exploring flower shape and architecture
(Annick Dubois)
En savoir
plus…
Wild
and cultivated roses harbor a huge diversity of flower morphologies,
colors and scents, making them a particularly intriguing model for the
study of natural and artificial evolution of floral traits. Our group
focuses on floral architecture, especially on the genetic control of
petal shape and petal number. While wild roses all have five petals,
most cultivated roses have double flower ranging from 10 petals to as
many as 200. We will describe our current approach to study molecular
mechanisms and the genetics of double flower formation. Genetic data
demonstrated that the double flower character is under the control of a
major and dominant locus. We use a combination of genetic, molecular
and transcriptomic approaches in order to identify the gene responsible
for the double flower phenotype.

Deciphering recurrent blooming (Fabrice
Foucher)
En savoir
plus…
In
rose, recurrent blooming, the ability to flower several times a year,
has played an important role in the success of roses.
Continuous-flowering is due to a genetic mutation in a gene encoded a
floral repressor. Mutated plants do not produce anymore the floral
repressor and then flower continuously. This mutation was introduced in
Europe from old cultivated Chinese roses and progressively selected
during the 19th century, leading to the modern roses. By studying this
floral repressor, we bring new knowledge on the physiology of flowering
in rose and the different environmental and endogenous factors that
affects blooming.

Genotype x environment interaction on the
plant architecture in rose bush (Camille Li-Marchetti)
En
savoir plus…
Plant
architecture determines the shape and visual quality of ornamental
plants like rose bush and is therefore a key concern for plant breeders
and nurseries. Both genetic and environmental factors and their
interaction modify plant architecture. To have a better understanding
and controlling of these factors should allow an enhanced cultural
practice mastering while reducing the use of chemicals as growth
regulators.
The effect of three environmental factors (water
restriction, quality of light and mechanical stimulation) was assessed
on the architecture of five rose bush cultivars. These works showed
that some architectural components were modified with different
amplitudes according to the cultivars.

Founded
in 1899 by its owner Jules GRAVEREAUX and the landscape architect
Edouard ANDRE, the Val-de-Marne rosary at L’Haÿ-les-Roses is over a
century old. It is probably the oldest rose garden in Europe and maybe
in the world, because if enthusiasts were already collecting roses,
this was the first time that a garden was dedicated to the queen of
flowers. Like many other historic gardens, the Val-de-Marne rosary is a
cultural and timeless reference that must be kept in the same
condition, frozen in time. But this particular situation may cause some
technical problems…

The Noisette rose project in France
(Bernard Mandô, Mathilde Liorzou)
En savoir
plus…
Created by Jules Gravereaux, the Roseraie
du Val de Marne de l’Haÿ,
located 10 km south of Paris, is the largest historic rose garden
of France. Noisettes roses are of particular interest. They had a
parallel American and French early development and represented in the
1810-1830 an original new group of reblooming roses with climbing
habits. From our collection of 70 Noisettes, we established a
core-collection for the conservation of the group. We brought together
many old documents and pictures, from books, magazines and catalogues,
for comparisons. A huge number of photographs were collected to unravel
the botanical and morphological characters for better descriptions and
identifications, allowing most of our specimens with a reference
statute.
In collaborations with
the GDO research team of Angers (INRA, ACO, University of Angers),
using the phenotypic and genotypic data, a genetic structure was
conducted. The comparative studies (as pedegree reconstruction or
global structuration) will be presented and discussed. This analysis
will be extended and completed to other clones through partnership with
other rose gardens worldwide.

Fragance, from the scientific point of
view (Sylvie Baudino-Caissard)
En
savoir plus…
The
rose is the queen of flowers and its fragrance has enchanted man since
the Greek antiquity. Roses are widely used as garden plants and for the
cut flower market. They are also used for the production of essential
oil for the cosmetic and perfume industries. A lot of botanical roses
are scented but despite the efforts of the breeders, not all modern
roses are fragrant. To understand why some roses are scentless, we are
studying several genes involved in the biosynthesis of scent in rose.
For example, we recently characterized the enzymes responsible for the
so-called 'tea scent' emitted by Chinese roses.

The magical world of rose fragrances
(Jacques Mouchotte)
En savoir
plus…
Roses’
perfume diversity is as wide as roses’ colors or flower shape. The rose
for the fragrance industry has a rather narrow meaning. Essential oil,
concrete and absolu manufacturing method are described. The
relationship with Grasse’s perfume companies allowed a better modern
roses’ fragrances description, some natural smells inspired perfumers
to create new prestigious commercial products. The head space is a
technique allowing the trapping in vivo from fragranced exhalation and
leading to chemical analysis to identify molecules to confirm
perfumers’s descriptions. Is this rose fragranced? In which conditions
is the fragrance better exhalated? The physiological perception
mechanisms are in fact a spatial form recognition and they relate to

How to create a (Rose) perfume (Martin
Gras)
En savoir plus…
The perfumer has about
6000 raw materials at his disposal, "naturals" and "synthetics".
The "synthetics" can be produced by analysing and synthesizing
the "naturals".
The creation of perfumes can take place in different ways:
- By imitation: the perfumer works on a perfume
as close as possible to the odor of a rose,
- By variation: the perfumer
reveals and underlines the various facets of a rose such as the spicy,
fruity, woody, aromatic or citrus notes,
- By imagination, which can be compared to a work
of art.
Perfumery becomes then an
abstract art. It's a rupture between the present and the past. The
perfumer starts from a blank page and makes new accords, of which the
Rose can be part of it, by using his imagination.
