摘　　要：为了解杨树枯落物的他感作用,研究了杨树枯落物水浸提液对高粱、糜子、白菜、芫荽、小麦等5种植物种子萌发和幼苗生长的影响。结果表明:杨树他感作用是存在的,不同浓度杨树枯落物水浸提液对5种植物种子萌发及幼苗生长有不同他感作用。The effects of Populus litter extract on seed germination and seedling growth of five kinds of plants(Sorghum bicolor,Panicum miliaceum,Brassica pekinensis,Coriandrum sativum,and Triticum aestivum)were investigated to understand the allelopathy of Populus litter.The results showed that Populus allelopathy existed,and different concentrations of Populus extract had different effects on seed germination and seedling growth of the five kinds of plants.This indicated that different concentrations of Populus litter water extract had different allelopathy on seed germination and seedling growth of the five kinds of plants.
