Abstract
This research was conducted as a factorial experiment consisting of two factors in a completely randomized design with three replications during 2019 and 2020 at the Temperate Fruit Research Center, Horticultural Research Institute. The first factor was 10 genotype of almond and the second factor was drought stress at 2 levels. In this study, 10 selected almond genotypes were evaluated using some morphological traits such as: seedling height, trunk diameter at the top of the graft region, new branch growth length and leaf yellowing and abscission. Also, in order to determine the resistant and sensitive genotypes, some physiological indicators under drought stress conditions such as: chlorophyll content index based on SPAD criteria, relative leaf water content and chlorophyll fluorescence were evaluated. Among the studied genotypes A-7-100 was the most resistant and A-124-1 was the most sensitive genotypes.
