In computer graphics, models describing the fractal branching structure of trees typically exploit the modularity of
tree structures. The models are based on local production rules, which are applied iteratively and simultaneously to
create a complex branching system. The objective is to generate three-dimensional scenes of often many realisticlooking
and non-identical trees. Our goal, instead, is to visualize the growth of a prototypical tree of certain
species. It is supposed to look realistic but, more importantly, has to conform with real, measured data. We
construct a tree model being similar to existing ones and extend it by coupling the branching production rules with
dynamic tree-growth rules. The latter are based on equations derived from measured street tree data for London
Plane tree (Platanus acerifolia) such as tree height, diameter-at-breast-height, crown height, crown diameter, and
leaf area. We map the global, measured parameters to the local parameters used in the tree model. The mapping
couples knowledge from plant biology and arboriculture, as we deal with trees that are trained and manipulated to
achieve desired forms and functions within highly urbanized environments.

Tige
La tige est chez les plantes à fleurs, l'axe, généralement aérien, qui prolonge la racine et porte les bourgeons et les feuilles. La tige se ramifie généralement en branches et rameaux formant l'appareil caulinaire. Elle diffère de la racine par la présence de nœuds où s'insèrent les bourgeons axillaires et les feuilles, par l'absence de coiffe terminale et par sa structure anatomique. La transition entre racine et tige se fait dans le « collet ». Il peut exister des tiges souterraines comme il existe des racines aériennes.

Comparative analysis of axillary and floral meristem development
Vojislava Grbić
Abstract: Axillary and floral meristems are shoot meristems that initiate postembryonically. In Arabidopsis, axillary meristems give rise to branches during vegetative development while floral meristems give rise to flowers during reproductive development. This review compares the development of these meristems from their initiation at the shoot apical meristem up to the establishment of their specific developmental fates. Axillary and floral meristems originate from lateral primordia that form at flanks of the shoot apical meristem. Initial development of vegetative and reproductive primordia are similar, resulting in the formation of a morphologically defined primordium partitioned into adaxial and abaxial domains. The adaxial primordial domain is competent to form a meristem, while the abaxial domain correlates with the formation of a leaf. This review proposes that all primordia partition into domains competent to form the meristem and the leaf. According to this model, a vegetative primordium develops as leaf-bias while a reproductive primordium develops as meristem-bias.
Key words: SHOOTMERISTEMLESS, LATERAL SUPPRESSOR, AINTEGUMENTA, adaxial primordial domain, abaxial primordial domain, shoot morphogenesis.
Résumé : Les méristèmes axillaires et floraux sont des méristèmes caulinaires qui s'initient post-embryonnairement. Chez l'Arabidopsis, les méristèmes axillaires produisent des ramifications au cours du développement végétatif, alors que les méristèmes floraux donnent des fleurs au cours du développement reproductif. Dans cette revue, l'auteur compare le développement de ces méristèmes, dès leur apparition au niveau du méristème du bourgeon apical jusqu'à l'établissement de leur développement spécifique. Les bourgeons axillaires et floraux proviennent de primordiums latéraux qui se forment sur les côtés du méristème apical caulinaire. Le début du développement des primordiums végétatifs et reproductifs sont semblables, conduisant à la formation d'un primordium morphologiquement défini comportant des domaines adaxiaux et abaxiaux. Le domaine primordial adaxial peut former un méristème, alors que le domaine abaxial correspond à la formation d'une feuille. L'auteur propose que tous les primordiums se répartissent dans des domaines capables de donner naissance au méristème et à la feuille. Selon ce modèle, un primordium végétatif se développe avec un biais foliaire, alors qu'un primordium reproductif se développe avec un biais méristématique.

Abstract - In vitro expression of the organogenic capacities of the axillary buds of plantain (Musa spp.) suckersIntroduction. The micropropagation of banana is usually carried out starting from shoot tips, therefore starting from only one explant per sucker. In addition, the production of vitroplants is often limited by the availability of suckers and the percentage of somaclonal variations increases with the number of subcultures. It would be thus interesting to have a greater number of explants per sucker to produce the same number of vitroplants but with fewer subcultures. The exploitation of the axillary buds present in great number on a banana sucker would make it possible to increase the number of explants usable for its multiplication. Thus, the objective of our work was to evaluate the capacities of the in vitro proliferation of the axillary buds compared with those of shoot tips. Materials and methods. Shoot tips and axillary buds taken from cultivar Big Ebanga (AAB, plantain False Horn) suckers were subjected to three types of disinfection: a disinfection by buckling, a modified traditional disinfection and a traditional disinfection. They were then placed to grow on MS culture medium. The effect of several concentrations in benzylaminopurine (BA, cytokinin) was studied regarding the precocity of the axillary bud proliferation. Results and discussion. Traditional disinfection gave the lowest rates of infection: 30% for the axillary buds and 5% for the shoot tips. The axillary buds proliferated precociously and produced adventitious buds as of the first subculture whereas the shoot tip explants proliferated only starting from the second or the third subculture. This early proliferation was accelerated in the presence of (2 and 4) mg BA·L-1. The number of shoots given by each type of bud was not significantly different. Conclusion. The axillary buds are a good starting material for in vitro culture. Their use makes it possible to regenerate a great number of vitroplants starting from only one sucker and, thus, increases the potentialities of in vitro production of healthy plantain vegetal material. The conformity of the seedlings resulting from these axillary buds will be the subject of future studies in the field.
Résumé - Introduction. La micropropagation in vitro du bananier est habituellement réalisée à partir du bourgeon caulinaire, donc à partir d'un seul explant par rejet. Par ailleurs, la production de vitroplants est souvent limitée par la disponibilité en rejets et le pourcentage de variants somaclonaux augmente avec le nombre de subcultures. Il serait donc intéressant de disposer d'un plus grand nombre d'explants par rejet afin de produire un même nombre de vitroplants avec moins de subcultures. L'exploitation des bourgeons axillaires présents en grand nombre sur un rejet de bananier permettrait d'augmenter le nombre d'explants utilisables pour sa multiplication. L'objectif de nos travaux a donc été d'évaluer les capacités de prolifération in vitro des bourgeons axillaires en comparaison de celles du bourgeon caulinaire. Matériel et méthodes. Des bourgeons caulinaires et axillaires prélevés sur des rejets du cultivar Big Ebanga (AAB, plantain faux corne) ont été soumis à trois types de désinfection : une désinfection par flambage, une désinfection classique modifiée et une désinfection classique. Ils ont été ensuite ensemencés sur un milieu de culture. L'effet de plusieurs concentrations en benzylaminopurine (BA) a été étudié sur la précocité de la prolifération des bourgeons axillaires. Résultats et discussion. La désinfection classique a donné le plus faible taux d'infection (30 %) chez les bourgeons axillaires. Les bourgeons axillaires ont proliféré précocement et ont produit des bourgeons adventifs dès la première subculture, alors que les bourgeons caulinaires n'ont proliféré qu'à partir de la deuxième ou troisième subculture. Cette prolifération précoce a été accélérée en présence de (2 et 4) mg BA·L-1. Le nombre de pousses formées par chaque type de bourgeon n'a pas été significativement différent. Conclusion. Les bourgeons axillaires sont un bon matériel de départ pour la culture in vitro. Leur utilisation permet de régénérer un grand nombre de vitroplants à partir d'un seul rejet et augmente ainsi les potentialités de production in vitro de matériel végétal sain chez le bananier plantain. La conformité au champ des plants issus de ces bourgeons axillaires fera l'objet d'études ultérieures.
