Morphology, Physiology and Analysis Techniques of Grapevine Bud Fruitfulness: A Review

Grapevine reproductive development extends over two growing seasons (vegetative cycles), for the complete formation of inflorescences and clusters. Induction floral differentiation, mechanism that leads to structures inside dormant buds, is a complex process divided into three well-defined stages (formation anlagen, inflorescence primordia flowers). This sequence comprises morphological, biochemical, physiological events, influenced by set environmental endogenous factors. Inflorescence determines potential number clusters will be formed in following season. Thus, during bud dormancy, viticulturists winemakers can obtain first yield prediction through determination fruitfulness. information allows adjustments made load, promoting balanced fruit quality higher commercial value. The present review describes morphology physiology primordia, as well discusses main abiotic biotic factors involved, including disorder known primary necrosis. In same way, we intend approach more used techniques analysis fruitfulness its importance robust forecasting.
