Effect of salicylic acid on yield and yield component of grapevine (Vitis vinifera) under salinity stress condition
Journal Title: International Journal of Farming and Allied Sciences - Year 2017, Vol 6, Issue 1
Abstract
Salinity is one of the limiting factors in agricultural production. Salicylic acid, as a plant growth regulator, is able to increase the salt tolerance of crops. Therefore, the effects of salicylic acid on quantitative and qualitative traits and some physiological parameters of grapevine (Cul. Ruby) under saline conditions was studied in Khash, Iran. The treatments include foliar application of four concentrations of salicylic acid (0, 0.1, 0.5 and 1 mM) in a randomized complete block design with three replications. Results showed that the effect of salicylic acid on yield, bunch number, bunch width, bunch weight, berry length and berry number per bunch were significant. But there were no significant effects recorded for bunch length. The effect of salicylic acid on the growth and yield were significant. Based on the results of this research, using 1 mM salicylic acid to increase the yield of Ruby grapevine under salt stress conditions is recommended.
