摘要： 为研究高油玉米花粉对普通玉米籽粒性状及含油量的影响,通过3个普通玉米品种与3个高油玉米品种混种,利用高油玉米花粉为普通玉米授粉,试验结果表明:通过花粉直感效应,普通玉米在接受高油玉米花粉后籽粒产量提高或变化不大,胚的重量显著增加。普通玉米和高油玉米杂交与相应的普通玉米自交相比,籽粒中胚的比重大大增加。籽粒中含油量的增加很大程度上是由于胚在籽粒中比重的增加引起的。

Abstract: Through interbreeding of three high-oil maize and three normal maize varieties,high-oil maize pollen into common maize pollination,we did some researches on the influence of high-oil maize pollen to common maize kernel traits and oil content.Experimental results showed that,by heterosis,common maize grain yield had little increase or change after high-oil maize pollen,but embryo weight increased significantly.Compared common corn and high-oil corn hybrids with the corresponding common corn inbred,the proportion of grain embryos increased greatly.Crain oil content increase was largely due to increase of embryo in the proportion of grain.
