摘要:
本研究以甘草、黄芩和桔梗为化感受体,探究不同浓度的元宝枫凋落叶浸提液对3种中草药种子萌发和幼苗生长的影响,以期为北京元宝枫林下中草药的种植提供理论依据。结果表明:元宝枫凋落叶浸提液对甘草和黄芩的种子萌发表现出“低促高抑”效应,而对桔梗表现为抑制作用。元宝枫凋落叶浸提液对3种中草药种子萌发和幼苗生长的化感效应为桔梗>黄芩>甘草。3种中草药幼苗叶片的叶绿素含量在不同浓度处理下均低于对照。元宝枫凋落叶浸提液处理使黄芩幼苗叶片的超氧化物歧化酶(SOD)活性升高,黄芩、甘草幼苗叶片的过氧化氢酶(CAT)活性随浸提液浓度的升高先升后降,3种中草药幼苗叶片的丙二醛含量随浸提液浓度的升高呈先增加后减少的趋势。综上,元宝枫林下应避免种植桔梗,适宜种植甘草和黄芩。
