The seed embryoes were penetrated by 〓 ion beams of 75 MeV/u and the seed endosperms were implanted by the proper degraded 〓 ions, and soluble protein of the seedling in M1 generation was divided into 5 sections to analyze their changes at different molecular weight. 1 In comparison with control, the relative content of the second section (molecular weight is heavier in all sections) of all irradiated materials got down, while the relative content of the fifth section (molecular weight is the lightest) of those went up. 2 The penetrating seeds made the relative content of the first section (molecular weight is the heaviest) and the third section (mid-molecular weight) drop, while the fourth section went up. Moreover, the changes of the third section and the fourth section of the penetrated materials were clearly different from those of the implanted materials. 3 The difference between implanted embryo and implanted endosperm existed in deeper dropping of the first section and higher rising of the fifth section on relative content of soluble protein of the latter. 4 On irradiated materials at lower doses, there were exceptional changes of soluble protein, it may be thought that there was excited effect of low dose.

1.75MeV／u 〓O〓离子经过适当降能后注入小麦种子的不同部位和贯穿整个种子，对其M1代幼苗的可溶性蛋白质组分以及电泳中不同区段蛋白质组分相对含量加以分析，结果表明：1）同对照相比，随着辐照剂量的增加，所有辐照材料第二区段蛋白质组分的相对含量下降；而第五区段蛋白质组分的相对含量升高。2）种子的贯穿处理，同时也引起第一区段和第三区段蛋白质组分相对含量的下降以及第四区段的升高；其中第三、四区段的变化明显区别于注入效应。3）注入胚和胚乳的区别在于后者第一区段蛋白质组分相对含量的较大下降和第五区段的较大提高。4）小剂量辐照的材料，可溶性蛋白质组分的变化异常，可能与低剂量辐射兴奋效应有关。
