摘要: 以不同浓度的水杨酸溶液对水仙叶片进行喷雾处理,发现不同浓度的水杨酸均能起到矮化植株和提高叶、根及花瓣中超氧化物歧化酶(SOD)和过氧化氢酶(CAT)的活力,降低过氧化物酶(POD)的活性和丙二醛含量,使膜质透性降低,花期有不同程度的延长,其中以3 mmol/L处理效果较佳。

Abstract: The leaves of Narcissus tazetta L.were sprayed with different concentrations of Salicylicacid (SA) . After treated with SA, the dwarfing effect are significantly different and the activities of Superoxide dismutase (SOD), Catalase (CAT) in the leaves 、root and petals were increased. While the activities of Peroxidase (POD) and contents of Malonadehyde (MDA) were decreased.Aad the Permeability of plasma membrance (PMP) was decreased,the florescence was prolonged with different concentrations of SA ,in which the 3 mmol/L was the best.
