- Anatomical changes in the peach (Prunus persica (L.) Batsch.) flower buds were defined and then assessed and correlated with the phenological stage from early dormancy through to flower opening. The peach flower bud, unlike the vegetative bud, shows a continuous anatomical development during the late autumn and winter dormancy period, even though there are no obvious macroscopic changes. Sterile whorls differentiate rapidly in late summer through early autumn. In contrast, fertile whorls develop very slowly during winter; their rapid development begins in late winter and continues through early spring. The androecium develops throughout the winter, while the gynoecium develops in late winter. By late winter, the anthers begin to undergo microsporogenesis and microgametogenesis and the ovaries have formed ovules. Vascular connections between flower primordia and branch wood are complete by late winter, when rapid phenological changes begin. At this point in time, the peach floral bud enters a “rapid maturation phase” that ends in flower opening. Thus, for the peach flower bud at least, the concept of dormancy as “a temporary suspension of visible growth of any plant structure containing a meristem” that was proposed by earlier researchers appears inappropriate. Rather, cell division, enlargement, and differentiation, which lead to organogenesis, take place throughout the entire “dormancy” period.
Les auteurs ont défini les changements anatomiques des bourgeons floraux de la pêche (Prunus persica (L.) Batsch.), puis les ont évalués et corrélés avec les stades phénologiques, du début de la dormance à l’ouverture des fleurs. Le bourgeon floral de la pêche, contrairement au bourgeon végétatif, montre un développement anatomique continu au cours de la période de dormance de fin d’automne et d’hiver, même s’il n’y a pas de changements macroscopiques évidents. Les verticilles stériles se différencient rapidement de la fin de l’été jusqu’au début de l’automne. Au contraire, les verticilles fertiles se développent très lentement au cours de l’hiver et leur développement rapide débute à la fin de l’hiver, de façon continue jusqu’au début du printemps. L’androcée se développe tout au long de l’hiver, alors que le gynécée se développe à la fin de l’hiver. Vers la fin de l’hiver, les anthères commencent à subir la microsporogénèse et la microgamétogénèse et les ovaires ont formé les ovules. Les connexions vasculaires entre les primordiums floraux et le bois des rameaux se complètent vers la fin de l’hiver, lorsque surviennent les changements phénologiques rapides. A ce moment, le bourgeon floral de la pêche entre dans une « phase rapide de maturation » qui se termine avec l’anthèse. Ainsi, du moins dans le cas du bourgeon floral de la pêche, le concept de dormance comme « suspension temporaire de croissance visible de toute structure végétale contenant un méristème », proposé antérieurement, semble inapproprié. Au contraire, la division, le gonflement et la différenciation des cellules conduisant à l’organogénèse s’effectuent tout au long de la période de « dormance ».
