Effect of lanthanum on pistachio plant (Pistacia vera L.) under salt stress

Lanthanum is a member of the rare metals group that has multiple roles in plant growth and is used to cope with various stresses. In order to investigate the effects of interaction between lanthanum and salt treatment on some physiological indicators of pistacia, the present study was carried out based on a factorial experiment in a completely randomized design with three replications. Experimental factors included in the experiment include different concentrations of lanthanum (0, 1.5.and 10 mM) and different levels of salt (0, 100 mM). The parameters studied included chlorophyll a, b and total, malondialdehyde and other aldehydes. The results showed that chlorophylls significant decreased during treatment with salt stress, while the level of malondialdehyde increased. The lanthanum in the most cases increases the chlorophyll content in the control plant, while the levels of lipid peroxidation are reduced. The results of this study showed that lanthanum is somewhat able to increase the resistance of pistachio plants to salt stress
