Study of resistance to salinity among controlled crosses of pistachio

In this experiment, 32 female varieties in pistachio plantation areas of Kerman, Rafsanjan, Sirjan and Shahrbabak were used. After artificial cross between 32 female varieties, the obtained hybrid seeds were sown and the produced seedlings tested under saline conditions in glasshouse. After salinity tests, the following characteristics were measured and evaluated: Number of alive seedlings, alive leaves, length of stem, dry weight of aerial organs and root, mineral elements of root and stem. The data were analyzed statistically in a completely randomized design with three replicates. The results indicated that the female varieties included: ‘Ibrahimi”, “Sirizi”, “Jandaghi”, “Poustkaghazi”, “Fandoghi-”, “Badami_e_Zarand”, Seiffadini” and “Sarakhs” are salt tolerant. The results indicated that the sodium content of stem with aliveness of seedling is negative contingent. Also accumulation of sodium and magnesium ions in root and stem caused desiccation of leaves in seedlings, in total salinity reduction of weight in root and stem.
