摘　　要：用ＣＯ_２，Ｎ_２和Ｈｅ－Ｎｅ３种不同波长的激光器分别对小麦品种冀早１５，冀麦１８进行萌动胚照射处理，对处理后第２代（Ｌ_２），第３代（Ｌ_３）材料进行研究。结果表明：激光对小麦种胚具有生物学效应，可以诱导某些农艺性状的变异。但是不同波长激光照射的效应和方向在小麦不同的遗传背景下存在差异。同时还讨论了某些农艺性状之间存在相关关系的可能性。The sprouted embryos of two wheat varieties Jizao 15 and Jimal 18 were irradiated bythree different wave length of laser. The second and the third generations (L2 and L3 ) werestudied; the results showed: laser can induce the biological variation in wheat, but the effectchanged under the different conditions. Meanwhile, the paper also discussed the possible relationship among some agricultural traits.
