摘要/Abstract

摘要： 离子注入黑麦的生物效应，有生理变异，也有遗传变异，经过低能N+离子束辐照，选出黑麦284-2，其减数分裂的染色体观察，在中期I和终变期，所有细胞均出现一个相邻式互环状四价体或交替式∞状四价体，其比例为1：1，M1代体细胞染色体出现两对染色体畸变，经C分带的带型分析，获得了1R和4R的染色体易位。本文还提出了黑麦284-2

Abstract: Iradiation with ion beam could cause both physiological and genetic variations. After the seeds of a pure line of rye, AR132,were irradiated with N+ ion beam,an abnormal individual plant, 284-2,was found whose morphological characters were quite different from those of the others. Microscopic observ
