L'organogènese inflorescentielle dans les bourgeons anticipés de vigne (Vitis vinifera L. cépage Pinot)

Organogenesis of inflorescences in the lateral buds of grapevine (Vitis vinifera L. cv. Pinot)The formation of inflorescences in lateral buds has been investigated by studies of longitudinal sections of paraffin-embedded lateral buds. The lateral buds at position 6 (from the base) were collected from non-decapitated shoots, from the middle of May to the end of June. The different developmental stages of inflorescence and also a chronological analysis have been described. The observations inform about the organogenetic ch aracteristics which occur in the absence of decapitation of the main shoot
