摘要
小麦不同生育期导入豌豆花ＤＮＡ的效果不同。返青期导入ＤＮＡ使小麦种子蛋白质含量增加２２．６１％，新增加４７ＫＤ和７１ＫＤ两种组分，而且这种变异可以遗传给Ｆ＿２代；拔节、抽穗、开花期导入ＤＮＡ仅使小麦种子千粒重增加１０％～１２％，而对小麦种子蛋白质组分无影响。
The different effects are produced after the injection of DNA form peaflower into wheat plants during different growth stages of wheat.The tunring greenstage is the optimum period for the injection of DNA. After the injection,the seed pro-tein content can be increased by 22.61%with two new proteins 71KD and 47KD ap-peared,which can also be inherited to the progeny.The injections of pea DNA in stempushing,heading and blooming stages can only add the thousand-grain weight by 10%～12%,but with no effects on the components of wheat seed proteins.
