摘要
探讨了麦田杂草播娘蒿对小麦早期生长发育的影响。发现播娘蒿种子淋洗物对小麦种子萌发和幼苗初期生长主要表现抑制效应,但淋洗物中的个别成分又有促进效果。证明了播娘蒿与小麦之间有生化他感作用存在,认为生化他感作用是播娘蒿作为麦田杂草影响小麦生长发育的另一种方式。
The effect of flixweed tansymustard as a weed in wheat field to early growth and development of wheat is investigated.It is found that the drenched substances of flixweed tansymustard seed predominatingly expressed inhibitory effect except promoting effect of individual fraction in initial wheat seedling growth.The results showed that the effect of allelopathy exists in flixweed tansymustard and wheat,and allelopathy is another manner on the growth and development of wheat is influenced by flixweed tansymustard.
