Abstract

Investigation of the cultivated TOMATO plant as a plant ideal system along with the DROUGHT resistant wild species can be useful to a better understanding of the mechanisms of DROUGHT resistance and improvement of TOMATO plants. To investigate the effect of DROUGHT stress on leaf Relative Water Content (RWC), ELECTROLYTE LEAKAGE and photosynthetic parameters in four species of TOMATO (a cultivated species and three wild species) at two levels of irrigation (field capacity and 40% field capacity) and four time periods (before stress, 10 days after stress, 20 days after stress and recovery) a factorial experiment based on Completely Randomized Design (CRD) was used. Among the tested species, cultivated species showed the highest decrease in RWC. ELECTROLYTE LEAKAGE was significantly increased in stress conditions. The rate of PHOTOSYNTHESIS and CHLOROPHYLL FLUORESCENCE yield in the two DROUGHT resistant wild species increased in stress conditions unlike of cultivated species, probably because of more adaptation of these species with low water conditions. The results showed that each of these species according to their own mechanism for dealing with DROUGHT stress, in one or more properties are superior to other species. it is therefore suggested that the different species for future studies (molecular) with different characteristics to be used.
