结球甘蓝叶对3种作物芽期与苗期生长的化感效应
Allelopathic effects of cabbage leaf on germination and seedling stages of three crops
摘要
Abstract
This research investigated,using petri dish filter paper and pot culture methods,the allelopathic effects and their physiological mechanisms of water extract of air-dried leaves of cabbage(Brassica oleracea var.capitata)on seed germination,seedling growth and physiological traits of three crops commonly cultivated in cold and arid areas of Shanxi Province:cocozelle(Cucurbita pepo),kidney bean(Phaseolus vulgaris)and maize(Zea mays).It was found that tested concentrations of water extract of cabbage leaves had a significant inhibitory effect on seed germination and seedling growth of the three tested crops(P<0.05),and the inhibitory effect increased with an increase in concentration.The inhibitory effect on radicle elongation of cocozelle and corn was stronger than that on germ elongation at the same concentration,while the inhibitory effect on radicle elongation of kidney bean was smaller than that on germination elongation at a cabbage leaf water extract concentration of 0.04 g·mL-1.The malondialdehyde content of kidney bean and corn seedlings after allelochemical treatments was higher than that of the controls.At cabbage leaf water extract concentrations of 0.06 and 0.08 g·mL-1,the antioxidase enzyme activities of test crop seedlings were enhanced,including SOD,POD and CAT.In multivariate analysis of the data,the allelopathic inhibitory effect of cabbage leaf extract on the three test crops ranked as cocozelle>corn>kidney bean.The differences in the inhibitory effect were related to the changes in malondialdehyde content and antioxidant enzyme activity in vivo.Therefore,planting kidney bean after cabbage may be one method to alleviate the negative effect of the stubble on the following crop.It is recommended that the aboveground parts should be completely removed during cabbage harvesting to avoid allelopathic substances accumulating in the soil and affecting the growth of the next crop.关键词
