Exposure to environmental stress due to salinity has been reported to result in adverse effects on the growth of plants. Studies have shown that the use of plant growth regulators (PGRs) has an ameliorative effect on plants grown under saline conditions. In the present investigation, effect of gibberellic acid (GA 3), 6-furfuryladenine (Kinetin) and benzyl adenine (BA) on Spinacia oleracea L. var. All Green, cultivated under saline conditions has been studied. After a pre-soaking treatment of six hours in 20 mg L -1 solutions of GA 3, Kinetin and 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 both chlorophyll a and b, and total chlorophyll showed an increase in PGR-treated plants compared to the untreated set. With the pretreatment, the reducing and non-reducing sugar content, as well as protein content of the leaves showed an increase in accumulation compared to the untreated plants. The accumulation of the stress metabolite proline, which increases under saline conditions, showed a significant decrease in the plants pretreated with PGRs.
