为了获知甘蓝型油菜角果的抗裂角性，采用自行研制的油菜角果抗裂角性碰撞检测装置对秦油7号成熟期油菜角果层的上、中、下3个部位的角果抗裂角性进行了试验研究，并分析了油菜角果大小差异对抗裂角性的影响。试验结果表明，成熟期甘蓝型油菜角果的抗裂角系数随着含水率的下降而减小；当含水率大于20％时，抗裂角系数与其含水率具有线性关系，含水率小于20％时，抗裂角系数显著下降并最终趋于0．16左右；秦油7号油菜角果的抗裂角系数在0．151～0．577之间；油菜角果的大小影响其抗裂角性，同一株油菜上角果尺寸大的抗裂角系数比角果尺寸小的大。

In this paper , we make some experiments on the silique shatter resistance from three parts of the oilseed rape ( Brassica napus L .):top, middle and bottom .These experiments are conducted on the testing device of silique shatter resistance invented by Jiangsu University using the method of improved random impact test .In addition , we also analyse the influence of the oilseed pod ’ s size on the silique shatter resistance .The results show that the silique shattering resist-ance index of mature oilseed rape ( Brassica napus L .) decreases with its moisture content decreasing .When the mois-ture content is larger than 20%, it is nearly linear relationship between the silique shattering resistance index and the moisture content .When the moisture content is less than 20%,the silique shattering resistance index decreases dramatic-ally, finally tending to be around 0.16.The silique shattering resistance index of oilseed rape (Qin You 7) ranges be-tween 0 .11 and 0 .577 .Besides ,the size of the oilseed rape has important effect on the silique shatter resistance .The bigger of the size , the greater of the silique shattering resistance index .
