Implication of Jasmonic Acid on Physiological Alterations on Salt Stressed Fodder Sorghum (Sorghum bicolor L.)

One of the main environmental factors that restricts growth and productivity sorghum is salt stress, which interferes with physiological processes including relative water content, NBI (nitrogen balance index), photosynthetic rate, etc. Agricultural land affected by soil salinity growing significantly worldwide, therefore, strategies are needed to improve tolerance most efficient one can be opted studying response against salinity. Salt stress reduced plant hormones such jasmonates, ABA, brassinosteroids, In order assess effects jasmonic acid (JA) (4.5, 6.5 & 8.5 mM) on properties (HJ 541 CSV 21F) grown in saline (4, 6 8 dS/m), green house experiment was executed a complete randomized design (CRD), three replications. The results shows adversely effected efficiency, chlorophyll antioxidants (anthocyanin flavonoids), nitrogen index, ash content used as suitable parameter for determining stress. While, foliar application improved stomatal conductance, Jasmonic concentrations mM had more noticeable effects. Percent enhancement transpiration 14.5% 13.4%, 16.7% 19.9%, 42.0% 58.0% HJ 21F, respectively at dS/m compared control. 21F performed better all levels after acid.
