Effects of salinity stress and foliar application of mineral elements and methanol on growth and some physiological traits of Coriandrum sativum L.

The idea was to assay the salinity (۰, ۵۰ and ۱۰۰ mM) impacts on Coriandrum sativum by the foliar application of nano-Zn, FeSO۴, MgSO۴ and methanol in possibly the salinity stress side-effects. A factorial experiment was arranged based on a completely randomized design with three replications in pot at Azarbaijan Shahid Madani University. The results revealed that salinity × foliar treatment significantly affected plant dry weight, relative water content, catalase activity, and elemental content of plants. The top recorded data (P≤۵%) for, plant dry weight and chlorophyll b content was with non-salinity × all foliar treatment. No-salinity and NaCl۵۰mM × methanol foliar application increased K content in plant. ۵۰ mM NaCl × FeSO۴ and nano-Zn spray increased catalase activity. Foliar spray with methanol, FeSO۴ and nano-Zn × no salinity increased N content. The highest relative water content belonged to no salinity × FeSO۴ and nano-Zn and NaCl۵۰ mM × FeSO۴ treatment. The top content of Fe, P, Ca and K/Na were recorded at non-saline conditions. ۵۰ mM NaCl increased the essential oil content of the plant. ۱۰۰ mM salinity treatment increased malondialdehyde, H۲O۲, Na and proline contents. Foliar treatment with FeSO۴ and MgSO۴ increased the essential oil content of the plant. As well Coriandrum sativum was sensitive plants to salinity, and foliar treatments especially FeSO۴ and nano-zinc ameliorated the adverse side-effects of salinity in plants.
