摘　　要：生化他感作用在草地植物种间竞争中具有重要的意义。用盆栽法,采用人工气候箱培养,研究了狼毒在土壤里腐解过程中对无芒雀麦的生化他感作用。结果表明:狼毒根对无芒雀麦幼苗茎叶的干物质积累具有抑制作用(P<0.01);对无芒雀麦的细胞质膜差别透性有明显的伤害作用(P<0.01);狼毒根的抑制作用大于狼毒茎叶。Allelopathy plays an important role in plants interaction. With the pot culture,the artificial climate box was used to study the allelopathy of Steura chamaejasme in decomposing process in soil on the acceptor Bromus inermis. The results indicated that the root,stem and leaf of S. chamaejasme had inhibitory effect on Bromus inermis’ dry weight of stem-leaf(P<0.01),and cell difference penetrability was increased(P<0.01).The inhibiting effect was stronger with an increase of amount required of Steura ch...
