摘　　要：以豇豆 (Vignaunguiculata )为供试植物 ,分别接种AM真菌Acaulosporalavis(光壁无梗球囊霉 ,菌号 :3 4)和Glomuscaledonium (苏格兰球囊霉 ,菌号 :90 0 3 6) ,通过温室盆栽试验 ,观察 2、10和 5 0mg·kg-1DEHP和DBP对菌根化植物生长的影响。试验结果表明 ,土壤添加DEHP和DBP后 ,植物地上和地下部分干重均有不同程度下降 ,高浓度DEHP和DBP还使植物叶绿素a和b的含量及根瘤数降低 ,接种AM真菌后明显促进了植物的生长 ,尤其对植物早期地下部分和植物后期地上部分的促进作用较为明显 ;同时 。In greenhouse,a pot experiment was carried out to study effect of DEHP and DBP of different concentrations (2,10 and 50 mg·kg -1)on growth of cowpea(Vigna unguiculata)inoculated with AM fungi Acaulospora lavis(strain No.34) or Glomus caledonium(strain No.90036).The experimental results indicated that shoot and root dry weights of the plant decreased when the soils were amended with DEHP and DBP.The contents of chlorophyll a and b and nodules were decreased at high concentrations of DEHP and DBP.After inoculation with AM fungi,plant growth was promoted, especially to early plant root and late plant shoot,at the same time, the contents of chlorophyll a and b and nodules increased.
