- 摘要:
- 以四川省普遍种植的‘快客35’白菜为试验受体材料,通过向土壤中加入不同浓度的银杏凋落叶水浸液,研究了银杏凋落叶水浸液对白菜生长及生理特性的影响。结果表明:银杏凋落叶水浸液对白菜生长的影响表现为抑制作用,并随着水浸液的浓度增加抑制作用加强;银杏凋落叶水浸液对白菜的光合色素含量的影响为低浓度促进高浓度抑制;随着银杏凋落叶水浸液浓度的增加白菜的超氧化物歧化酶(SOD)、过氧化物歧化酶(POD)活性逐渐升高,过氧化氢酶(CAT)活性和脯氨酸含量先升高后降低,丙二醛(MDA)、可溶性蛋白质含量无显著变化。
- Abstract:
- The effects of aqueous extract of Ginkgo litter leaves on the growth and physiological characteristics of Chinese cabbage ‘Kuaike 35’,which were commonly cultivated in Sichuan Province were studied by applying different concentrations of aqueous extract of Ginkgo litter leaves to the soil.The results showed that the effect of aqueous extract of Ginkgo litter leaves on the growth of Chinese cabbage was inhibited,and with the increase of the concentration of Ginkgo biloba extract the inhibitory effect was enhanced.The effects of aqueous extract of Ginkgo litter leaveson the photosynthetic pigment content of Chinese cabbage showed low concentration promote and high concentration inhibition.As the concentration of aqueous extract of Ginkgo litter leaves increased,the activity of SOD and POD in cabbage increased gradually,CAT activity and proline content increased first,and then decreased.MDA and soluble protein contents had no significant change.
