[Effects of salt stress on germination and in vitro growth of pistachio (Pistacia vera L.)].
In order to study the salinity tolerance of pistachio (Pistacia vera L.), embryos developed from mature seeds were isolated and cultured in vitro and subjected to different NaCl concentrations (0, 42.8, 85.5, 171.1 and 256.6 mM) for 30 days. The results showed that in vitro germination of embryonic axes was not affected by the salt concentration. However, the germinated embryo survival rates decreased from 100% for the control to 62.9% for the highest salt concentration (256.6 mM). In addition, the plantlet growth (length of aerial and root parts, number of leaf produced per embryo, as well as the production of total fresh and dry matter for both aerial parts and roots) showed significant differences according the various salt concentrations.
