氮离子束等诱变机理研究（二）

Study on Mutation Mechanisms of Nitrogen Ion Beam(Ⅱ)

不同诱变源（Ｎ＋束、γ－ｒａｙ等）与不同小麦样品互作，经光声效应分析和染色体结构和变异的鉴定，初步证实Ｎ＋束正如γ－ｒａｙ一样可作为染色体畸变和基因重组的有效诱变源。

According to the analysis on PAS spectra,quantities,structure variations of chromosomesand the interactions between wheat samples and inducing sources(N+,γ-ray···etc.),preliminaryevidences were obtained that N+beam,yust like other inducing sources,such as γ-ray,could beregarded as an effective induing source for inducing aberrations and gene recombinations.
