Moeinrad Assistant professor, Islamic Azad University, Mashhad, Iran Journal Article 2007 11 25 To determine the relative salt tolerance and/or resistance in seedlings of pistachio genotypes, four pot experiments<br />were conducted. In experiments 1 and 2, the effects of salinity on growth indices were studid. Experiments were done<br />in the form of split plot based on RCBD. In each experiment, mainplots consisted of different electrical conductivities<br />of irrigation water (ECiws). In experiment 1, the seedlings of seven cultivars (cvs.) of Pistacia vera L. (Momtaz,<br />Akbari, Kale-ghoochi, Owhadi, Ahmad-aghai, Sarakhs, Badami-riz) and also P. atlantica sub. Mutica (Baneh) were<br />allocated in subplots. In the second experiment, three cvs. of P. vera L. (Badami-riz,Momtaz and Owhadi) with<br />different salt tolerances were used. In order to determine the resistance of pistachio cvs. in respect to seedlings<br />survival, experiment 3 was done. In experiment 3, salinity treatments continued upto 70% of leaf damaging in<br />seedlings. In experiment 4, the effects of salinity on pistachio seedlings in regards to chlorophyll-meter figures and<br />proline contents studied. Nevertheless, the ratio of damaged leaves, K/Na ratio and total dry weight was determined.<br />In experiment 4, the relationship between some physiological traits and salt tolerance in pistachio genotypes<br />determined. We observed that not only salt tolerance varies cv. to cv., but also it changes in different sources of a<br />given cv. In order to determine the salt tolerance of pistachio genotypes, the sensible traits (relative percent of total<br />dry weight and seedlings survival) were more reliable than traits such as K/Na ratio, chlorophyll meter figure, and/or<br />a single physiological character as same as leaf proline content. https://jdesert.ut.ac.ir/article_36296_b361c9845f7ac996d055931181dcfe06.pdf
