| 摘 要： | 本文研究了在我国东北地区广泛蔓延的菊科杂草－－豚草对大豆、玉米、小麦、水稻的化感作用，实验针对豚草的挥发物、茎叶和根的淋溶物、根区土壤水浸液等的化感活性进行了研究，研究发现豚草的挥发物对大豆和玉米的种子萌发有一定抑制作用，根区土壤对农作物无明显的作用；茎叶部分的水浸液对几种农作物的种子萌发和幼苗的幼根伸长有明显的抑制作用，同时使根系形态发生较大的变化，根系的水浸液对作物的幼芽伸长有一定的促进作用。

| Abstract: | Ambrosia artemisiifolia is a wide spread weed of composite in Northeast China. This paper studied the allelopathic effect of A. artemisiifolia, so as to elucidate it's spreading mecha nism and to find some ways to control it. After a series of experiments, we found some inter esting results: 1. Volatile of this weed has some inhibit effects on seeds germination of soybean and maize, the length of maize root treaed by volatile was shorter than that by control. 2. The water extract of the upper-ground part sh... |
