Abstract
Drought and salinity are among the most important abiotic stress factors. Although there is a growing interest to the sustainability of fruit growing in arid and salty areas, there are not enough studies. Therefore, this study was carried out for the determination of the effects of harpin protein at different salt concentrations in Pistachio (Pistacia vera L.) seeds. At the end of the treatment, there was a 20% decrease in plant height, 43% in root length, and approximately 40% in fresh and dry plant weight. Superoxide dismutase, catalase and ascorbate peroxidase antioxidant enzyme activities increased by 171%, 285% and 390%, respectively. In addition, the amount of chlorophyll a, chlorophyll b, and chlorophyll a+b (respetctively, 47%, 42%, 43%) was decrease. In addition, it was determined that harpin applications protected the chlorophyll content related to photosynthesis, increased the diameter of the stem and root and decreased the stress enzyme activities. Thus, applications of harpin protein may be beneficial to increase tolerance to drought/salinity stresses in pistachio plants, especially in the early stages of seedling development. These findings may pave the way for future research on stress management in sustainable fruit growing in arid and semi-arid areas.
