离子注入法诱变菊花及嵌合体分离的研究

Study on Ion Implantation Methold Mutation on Chrysanthemum and Separation of Chimera

采用离子注入的方法对2个地被菊品种自交种子进行辐射处理,对后代的种子发芽率,株高,冠幅,花色和花径等进行观察统计。结果表明:经过处理后的菊花形状均发生变异,M1代平均株高明显矮化冠幅增大;花径与亲本相比发生广泛分离,性状变异率在8%左右。在Fe^+注入株中出现花色嵌合体的现象,该嵌合体的特征是一朵花上出现2种颜色的相嵌现象,并且通过组培技术对嵌合体进行分离得到与母株性状相同花色不同的新菊花品种。

This test method of using ion implantation is two varieties of chrysanthemum into seeds from radiation treatment, the descendants of seed germination rate, plant height, crown, and carries on the observation and statistics, etc o Results showed that processed chrysanthemum shape variation are found, M1 average height increases obviously reduced crown; compared with the parent flower diameter widely separated, characters mutation rate at around 8% . Fe^＋ injection strains in the phenomenon in color,The characteristics of flower is chimeras appear on the two kinds of color are embedded phenomenon, through the tissue culture technology to separate the chimeric with different color of the same maternal characters of new varieties of chrysanthemum.
