摘要
从生化他感角度，研究了芒萁地上、地下部分水提液对油菜、白菜、水稻、绿豆、萝卜、玉米等农作物生长的影响。实验表明，芒萁地下部分水提液对所有供试植物种子萌发无抑制作用；地上部分水提液除对白菜、萝卜有极显著抑制作用外，对其它几种供试植物无抑制作用；两种水提液对全部供试植物的根生长和多数供试植物的苗高、全株鲜重有抑制作用；地上部分对幼苗生长的抑制强于地下部分；水提液对幼苗根生长的抑制强于对茎、叶。
In aspect of allelopathy,we studied the effects of the extract of terreneous part and subterreneous part from Dicranopteris pedata[WTBZ] on several crops growth.The experimental results show:Except the extract of terreneous part can restrain the budding of Brassica pekinensis and Raphanus sativus,the extracts haven't remarkable effects on the experimental crops.They can restrain the root length of all acceptors,the shoot height and wet weight of the majority.The terreneous part has stronger allelopathic effects on seedling growth than the subterreneous.The extracts can restrain the root growth more strongly than the leaf and stem.
