| 摘 要： | 在油菜成熟前的角果内就已经发芽(胚根突破种皮,并有不同程度伸长)的籽粒称为芽粒,具有芽粒性状的品种和资源材料从开花后35天左右就有芽粒产生,并随时间的增加而不断增多的趋势。不同品种和同品种不同个体(或株系)间芽粒的有无和多少差异较大,而与具有芽粒性状单株的花序部位无关。具有芽粒的种子其发芽势(率)和出苗率比正常种子均有不同程度下降。

| Abstract: | It is called the bud grain(Radicle was already break from seed coet,and stretched with varying degrees)which germinats within no-ripe fruits before harvest stage in rape,it is begun to shaping from 35 days after flowering in varieties and resources with bud grain property,and uninterrupted add as time goes on.The difference of bud grain which having or nothing and many or few between alike variety and different varietes.and nothing relation with flow head place.The germinating viabilty and seedling rate of having bud grain rapeseed decreased with vary degree than common seed. |
