以青藏高原地区青海省东部干旱区域常见杂草旱雀麦（Bromus tectorum Linn）作为受体，用琼脂共培法对青藏高原青海省东部干旱区域8种主要栽培小麦品种进行化感作用的评价。结果表明：8种小麦品种对旱雀麦的发芽率、发芽势抑制强度为2．78％～69．44％，其中高原448抑制作用最强，乐麦5号抑制作用最弱，青春38、高原437、通麦1号对旱雀麦种子萌发的抑制率都达到10％以上，而互助红、互麦14则对旱雀麦种子萌发表现为负的抑制率。相关性分析得出：处理间化感作用的差异在根长、芽长、干重方面的 P值分别为0．0166、0．0194和0．0001，达到显著水平，鲜重 P值大于0．5，无相关性。利用化感作用效应指数（ RI值）作为化感指标，结合聚类分析得出高原448化感作用最强，青春38、高原437、通麦1号、阿勃化感作用中等，互助红、互麦14号、乐麦5号没有化感作用。

To evaluate allelopathy effects ,equal compartment agar method (ECAM ) was used to inoculate eight main wheat varieties from Qinghai province of the Qinghai-Tibet plateau with dry oats ( Bromus tectorum Linn ) that func-tioned as the receptor .The experimental results showed:eight varieties of wheat to Bromus tectorum Linn of Germination rate and potential inhibition range 2 .78% ~69 .44% .Gaoyuan 448 inhibition the strongest and Lemai 5 is the weakest , Qingchun 38、Gaoyuan 437、Tongmai1to Bromus tectorum Linn germination inhibition rate reached more than 10% , Huzhuhong、Humai 14 showed negative inhibition .Correlation analysis results:P value of root length is 0 .0166 shoot is 0 .0194 and dry weight is 0 .0001 reached a significant level ,the fresh weight of P values greater than 0 .5 ,no correla-tion .Using RI value as an allelopathic index ,as well as a cluster analysis ,one variety (Gaoyuan 448 ) was concluded to possess strong allelopathic effect ,four varieties(Qingchun 38 ,Gaoyuan 437 ,Tongmai 1 ,Abo) were found to be moderately allelopathic ,and three other varieties (Huzhuhong ,Humai 14 ,Leimai 5) were demonstrated to have no allelopathy .
