When the fibres are in contact , the resin will form a tricorne - a triangle with curved sides 在纤维互相接触时，树脂就形成一个曲边三角体- -一个带有曲边的三角形。
2.
The results showed that galium tricorne had allelopathic effects on all wheat varieties tested , but the allelopathic effects were significantly different on various wheat varieties , and the difference might he caused by the genetic traits of different wheat varieties 结果表明，猪殃殃对不同小麦品种均存在一定程度的化感作用，但是化感作用的强度在不同小麦品种间存在显著差异，这种差异可能是由小麦品种的遗传特性决定的。

With ri values as allelopathic index and through cluster analysis , these varieties could be divided into three groups , among which allelopathic effects of galium tricorne on xiaoyan 22 , yuanfeng 175 , xinong 979 , zhengmai 9023 and xinong 889 were relatively weak , so the five varieties had relatively strong anti weed potentials 以ri值为化感作用的评价指标，结合聚类分析的方法，将这15个小麦品种分为3组，其中猪殃殃对小偃22 、远丰175 、西农979 、郑麦9023和西农889等5个品种的化感作用较弱，这5个品种表现出较强的抗草潜力。
