Fruit bud differentiation in grapevine: A review
Keywords:
Grapevine, inflorescence primordia, bud differentiation, potential yieldAbstract
Grapevine (Vitis vinifera L.) reproductive development extends over two growing seasons (vegetative cycles) for complete formation of inflorescences and clusters, and reproductive cycle (development of a cluster). The process of induction and floral differentiation, which leads to creation of reproductive structures within dormant buds, is intricate and occurs in three distinct stages: formation of anlagen, inflorescence primordia, and flowers. This sequence of stages involves morphological, biochemical, and physiological changes, all influenced by a range of environmental and internal factors. The review describes the morphology and physiology of fruit bud differentiation, as well as discusses the main abiotic and biotic factors involved.
