The effect of lanthanum and calcium interaction on resistance increasing of pistachio (Pistacia vera L.) under salinity 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 calcium on some physiological indicators of pistacia under salt stress 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 calcium (0 and 10 mM) and salt (0 and 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 (100 Mm), while the level of malondialdehyde increased. The lanthanum and calcium (10 mM) treatment 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 possibly, lanthanum has been able to exert a positive effect on calcium and consequently the resistance of the pistachio plant to salt stress increases.
