Grapevine growth and fruit development.

Abstract

This chapter reviews the growth cycle (including branching, flower initiation, fruit set, fruit development and berry maturation) of grapevine, along with factors (such as plant growth regulators, environment and climate) that influence it. The fact that the vine is a perennial plant means that management is quite different to that for annual crops, as well as there being unique aspects to cultivating young versus established vines. An overarching concept, that of vine balance, is introduced as it has implications for decisions made from the very start of vineyard planning as to how the weather affects the vine after harvest. Fruit quality parameters are also mentioned, particularly with reference to grape berry maturation.
