摘要： The relationship between vascular water translocation in grapes and berry growth was investigated. Berry growth, firmness and turgor were measured, and the structure and function of the vascular bundles for water translocation was observed. During phase I fruit development, the dorsal and central vascular bundles rapidly translocated introduced dye in the pedicle. The speed of dye translocation was highest in the dorsal vascular bundles of phase I fruit with a speed of 0.97cm/h. After phase II, both the distribution of dye and the speed of dye translocation in the fruit vascular tissue decreased, with speeds in the dorsal and central vascular bundles being 0.08 cm/h and 0.72 cm/h, respectively. During phase III, the distribution of dye was still lower than phase I. After phase II, the walls of some xylem vessels were indistinct and broken. After phase III, even though the water translocation efficiency of the xylem decreased, sugar accumulation in the berry as well as osmoregulation increased.
