In order to assess the effect of salicylic acid (SA) on activities of acid phosphatase (APase, EC 3.1.3.2) in four pea (Pisum sativum L.) varieties viz. Meteor, Climax, Green feast and Rondo during seed development and germination the field experiment were conducted using split-split plot design. The seeds were soaked in 0, 0.1 and 0.01 mM SA aqueous solutions for six hours. The plants were sprayed at phenological growth stage BBCH 60 with three SA concentrations mentioned previously in the early morning when the plants had their 3rd leaf completely expanded. The highest APase activity was recorded for the variety Greenfeast and for pea plants treated with SA concentration 0.1 mM, while the pea plants treated twice i.e., seed priming plus foliar spray revealed maximum APase activity. During seed germination of pea the maximum APase activity was observed for the variety Green feast, SA 0.1 mM treated seeds revealed maximum APase activity, while the seeds raised from the pea plants whose seeds were primed plus foliar sprayed exhibited maximum APase activity.
