Abstract:

Cacti (Cactaceae) represent a family of highly specialized angiosperm plants with a native range of distribution restricted to the American continents. Columnar cacti of the sub-family Cactoideae evolved in adaptation to their arid or semi-arid habitats characteristics that distinguish them from most other dicot plants, e.g. the stem succulence with a strongly vascularized storage parenchyma and the presence of the spine wearing areoles. Although cacti have been in cultivation since the discovery of America, some studies even suggest the agricultural use in pre-colombian times, and many scien

Abstract:

Le fraisier se reproduit de manière sexuée (floraison) et asexuée (stolons). Ces deux modes, bien qu'antagonistes, sont agronomiquement importants : la floraison influence le rendement en fruits, tandis que les stolons permettent la propagation de variétés. Cette compétition a lieu notamment au niveau des bourgeons axillaires (AxB), qui se développent soit en branches pouvant se terminer par une inflorescence, soit en stolons. Comprendre le réseau génétique contrôlant le développement des AxB est crucial, car il affecte à la fois le rendement en fruits et en plants du fraisier.L'objectif de ma

Abstract:

The branching or tillering of crops is an important agronomic trait with a major impact on yield. Maintaining an appropriate number of branches allows the plant to use limited light resources and to produce biomass or yield more effectively. The branching process includes the initiation of the axillary meristem leading to bud formation and the further outgrowth of the axillary buds. Phytohormones, including cytokinins and auxin, are known to play major roles in regulating axillary bud outgrowth. Light signals, including light quantity and light quality, are among the most important factors reg

Abstract:

The removal of terminal buds (topping) and sucker control are two practices that have an impact on yield and quality of dark tobacco (Nicotiana tabacum L.). Topping breaks apical dominance and encourages the growth of axillary buds (suckers). Following topping, growth regulator chemicals known as suckercides are commonly used to prevent axillary bud growth. Research has demonstrated that topping time, height, and sucker control method influence the quality and yield of the final product. Delaying topping past a critical developmental stage has been shown to reduce leaf yield. Topping height va

Abstract:

Le débourrement du bourgeon axillaire est un processus clef au cours du développement de la plante, qui est contrôlé par des facteurs endogènes et exogènes. Au niveau du bourgeon, le facteur de transcription BRANCHED1 (BRC1) est l'un des principaux intégrateurs des voies de signalisations de ces facteurs. Sur la base des études précédentes, le niveau de transcription de RhBRC1 (un gène homologue de BRC1 chez Rosa hybrida) est contrôlé par le sucre et l’auxine.Cependant, les mécanismes moléculaires impliqués dans cette régulation restent à ce jour inconnus.Dans cette étude, nous avons montré qu

Le pommier (Malus Xdomestica Borkh.) cultivé en climat à hiver doux, avec un manque d'une quantité suffisante d'heures de températures froides, présente des anomalies morphologiques et physiologiques. Sur le plan de la phénologie, il s'agit notamment d'un débourrement printanier tardif et désynchronisé entre les différents bourgeons d'un même arbre. Sur le plan agronomique, la floraison et la nouaison sont irrégulières et étalées dans le temps et conduisent à une faible production de fruits.

Abstract:

Eucalyptus grandis and its hybrids is the most important and widely planted eucalypt in South Africa. It has a wide range of uses including pulpwood, poles, firewood, charcoal, flooring, mining, furniture and general carpentry. Conservation of plant genetic resources including those used in agriculture, horticulture and forestry has become an issue of common global concern. Cryopreservation involves the storage of plant material at ultra low temperature (-196°C). The techniques for cryopreservation currently in use are varied and include the older classical techniques and the new vitrif

Like other flowering plants, phalaenopsis must reach a certain size or chronological age befor it can respond to floral promoters. Based on flowering percentage, the juvenile period may persist 4 months in seedlings of Phal. amabilis grown in 5㎝pot. After phase transition at 5~6-month—old seedlings grown in 8㎝pot, juvenility ended and the plants became competent to perceive cool-temper

Disturbance is an important phenomenon affecting plant lives and shaping plant strategies in disturbed habitats. A variety of ecological concepts on individual plant response to injury has been proposed for specific natural ecosystems or growth forms. In central Europe, man-made habitats are often cases of disturbed places, so the aim of the thesis was to apply four chosen concepts on them. The thesis is composed of four original studies performed in two model ecosystems: recurrently disturbed ruderal place and regularly mown central European meadow.
