The berry itself has three main tissues that comprise it: Figure 1.seasonal grapevine phenological development. Unless there is an excess of water or fertility, shoot growth slows greatly or ceases. After harvest, grapevine leaves continue to photosynthesize until frost if temperatures are warm enough. As temperatures fall, vines gradually become more cold hardy, and sugars are converted to starch to be stored for the winter, mostly in perennial structures such as roots and trunks.
On the outside of the skin is the bloom, or waxy layer, that helps to prevent water loss.

Traditionally, gdd accumulation begins on april 1 and ends on october 31 in temperate regions of the northern hemisphere. The chilling requirement for grapevines is approximately 250 hours, but varies by cultivar and site. See full list on grapes.extension.org
Wolf (ed.), wine grape production guide for eastern north america (pp. Cluster primordia (uncommitted meristems or tissue that give rise to inflorescences or tendrils) initiation for next year's flower clusters and crop occurs simultaneously with bloom for the current crop—in other words, at the same time. The first phase of rapid berry growth. (winetitles) 1 winter bud 2 bud scales opening 3 wooly bud ± green. Leaves well exposed to sunlight during this time will result in more fruitful budsin the following growing season.

Most new mexico vineyard sites accumulate well over 250 chilling hours. During the next four to six weeks, sugar, pigments, and other flavor compounds increase in the maturing fruit, while organic acids decrease and change forms. The phloem is responsible for carbohydrate transport from the leaf canopy to the vine, and subsequently, to the berry. As temperatures warm in the spring, stored starch is converted to sugar and sap begins to move in the vine. The bud of a regent vine located between the stem and petiole. Up until veraison, berries represent the vine's mechanism for dispersing mature seeds, through consumption by birds or other vertebrates. Like most temperate zone deciduous fruit crops, grapevines require a chilling period(hours below 45°f) during dormancy for optimal budburst the following spring. See full list on aces.nmsu.edu
