Abstract: "The influences of different concns. of ASP and SMZ-TMP on seed germination of soybean (Glycine max) were studied. The results indicated that the germination percentages, vigor index and root development were increased by presoaking the seeds in ASP and SMZ-TMP solns. The optimal concns. of ASP and SMZ-TMP soaking solns. are 50 mg

Abstract: “The hypothesis that physiol. active concns. of salicylic acid (SA) and its derivs. can confer stress tolerance in plants was evaluated using bean (Phaseolus vulgaris L.) and tomato (Lycopersicon esculentum L.). Plants grown from seeds imbibed in aq. solns. (0.1-0.5 mM) of salicylic acid or acetylsalicylic acid (ASA) displayed enhanced tolerance to heat, chilling and drought stresses. Seedlings acquired similar stress tolerance when SA or ASA treatments were applied as soil drenches. The fact that seed imbibition with SA or ASA confers stress tolerance in plants is more consistent with a signaling role of these mols., leading to the expression of tolerance rather than a direct effect. Induction of multiple stress tolerance in plants by exogenous application of SA and its derivs. may have a significant practical application in agriculture, horticulture and forestry.”
