The effect of Salicylic acid on ion relations and some biochemical traits of two sugar beet cultivars under salinity stress
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 6, Issue 2
Abstract
Salinity of soil and irrigation water reduces yield of the crops such as sugar beet. To study the effect of salicylic acid (SA) on salinity tolerance of sugar beet cultivars this study, an outdoor pot experiment, was conducted as split factorial based on randomized complete block design with three replications during growing seasons of 2012 and 2013. The studied factors were three levels of SA (0 mM, 0.5 mM and 1 mM), two levels of salinity (150 mm sodium chloride and control) and two sugar beet cultivars (Jolgeh and Shariff). SA was applied as foliar spray along with salinity in the 4-leaf stage. Results showed that salinity caused a significant increase in membrane permeability, proline, proline / potassium, sodium, potassium / sodium and total soluble sugars in the roots and leaves, while foliar application of SA was significantly decreasing these traits. High correlation between proline and root and shoot dry weight revealed foliar application and proline increasing enabled the plant to tolerate salinity and finally resulted in increase of the root and shoot dry weight. Regarding to the results of sensitivity index, Jolgeh and Shariff were determined as semi-tolerant and semi-sensitive, respectively.
