摘　　要：以新麦9号为对照,对M6代离子束介导转大豆DNA的高蛋白小麦A,B株系生育后期旗叶的硝酸还原酶活性(NR),Chl(a+b),Chla,Chlb含量及Chla/b进行了分析。结果表明:B株系硝酸还原酶活性和Chl(a+b)含量比对照高,而A株系硝酸还原酶活性比对照低(5月23日除外),Chl(a+b)含量比对照高。The nitrate reductase activity, the content of Ch1（a＋b）, Ch1a and Ch1b, and the value of Ch1 a/b in flag leaves of the M6 wheat A and B strains transferred with soybean DNA by ion beam were studied,in which Xinmai 9 was used as control. The results showed that the NRA and Ch1（a＋b） content were higher in B strain than in control, but A strain has lower NR（except May 23 rd） and higher Ch1（a＋b） content compared with control.
