摘要

Grape Vitis vinifera L. is an important commercial fruit crop of India earning sizable foreign exchange. Grape cultivation is located in semi-arid regions with limited water resources. Water is the main factor limiting the yield and quality of grape. The yield and quality of grapes affected due to erratic rains and continuous dry spell. The attempts has been made for evaluation of various grape rootstocks for drought tolerance. The biochemical attributes like chlorophyll content and chlorophyll stability index have been considered for relative drought tolerance study. In cell, chloroplast is an important photosynthetic unit of the plant cells. The major damages to the chloroplast caused by water stress are the structural changes due to excessive swelling, distortation of lamellae, vesiculation and the appearance of the lipid droplets Paleg and Aspinall, 9. Therefore, it was felt necessary to generate the information on relative drought tolerant rootstocks of grapes based on the chlorophyll content and chlorophyll stability index.
