Abstract
Abiotic stresses, such as drought, can induce different morphological, physiological and molecular responses in the tea plants. Since there have not been any experiments on the screening of tea genotypes in terms of drought tolerance, this study was conducted to screen the drought resistance of 14 tea clones of Iran germplasm in a randomized complete block design with three replications, separately in two stressed and non-stressed conditions at Fashalam tea station. The results of grouping the clones under normal and stress conditions and comparing their results with the results of mean comparison of the agronomic and biochemical traits showed that in all cases, clones 100, Bazri and 399 were in the group that can be identified as the drought-tolerant group. Also, the results showed that in the most cases, clones 278, 276 and 285 were placed in a group that had low values for all of the traits and could be considered as a group that are susceptible to drought stress.
