Effects of Exogenous Salicylic Acid on Growth and Some Physiological Indexes in Jasminun sambac
摘要
Abstract
Objective] To research the effects of exogenous salicylic acid (SA) on growth and some physiological indexes in Jasminun sam-bac (L.) Ait.[Method] With potted J.sambac as the test materials, SA solutions in different concentrations were sprayed to seedling leaves. Changes of some morphology and physiological indexes in seedlings were analyzed.[Result] The number of leaves and flowers in J.sambac seedlings increased after spraying different SA concentrations, and the increase range was all greater than that in control(CK).Leaf number in 0.8 mmol/L SA treatment group enhanced the most significantly.Flower number in 1.2 mmol/L SA treatment group had the greatest enhance-ment.SA reduced the malondialdehyde and soluble sugar contents in certain degrees.Spraying a given concentration of SA promoted the in-crease of proline content in J.sambac leaves.Too high or too low SA concentration was not helpful to the increase of proline content.[ Con-clusion] Spraying suitable SA concentration increases the stability of membrane system, enhances resistance and promotes the growth and flow-ering of J.sambac.关键词
