Improvement of Salt Tolerance in Trigonella foenum-graecum L. var. PEB by Plant Growth Regulators
Journal Title: Журнал ÑтреÑÑ-физиологии и биохимии - Year 2014, Vol 10, Issue 2
Abstract
he crop yield is reduced under saline conditions and this hampers agricultural productivity. The incorporation of plant growth regulators (PGRs) during presoaking treatments in many crops has improved seed performance under saline conditions. In order to study the ameliorative effect of plant growth regulators, experiments were conducted to study the variation in organic constituents in the leaves of Trigonella foenum-graecum L. var.PEB, where the seeds were primed with different plant growth regulators and grown under NaCl salinity. After a pre-soaking treatment of six hours in 20 mg L-1 solutions of gibberllic acid (GA3), 6-furfuryladenine (Kinetin) and benzyl adenine (BA), the seeds were allowed to germinate and grow for forty-five days under saline conditions. On the analysis of mature leaves, it was observed that chlorophyll a and b, total chlorophyll and protein showed an increase in PGR-treated plants compared to the untreated set. The accumulation of the stress metabolite such as proline and sugars, which increase under saline conditions, showed a significant decrease in the plants pretreated with PGRs.
