| 摘 要： | 对“实践八号”返回式卫星搭载循化线辣椒种子M1代的植物学及孢粉学性状进行观察和分析。结果表明：循化线辣椒种子经太空诱变处理后,M1代中株高、茎粗、叶长、叶宽等主要植物学性状变异幅度和变异系数均比对照大;M1代与对照进行孢粉学研究表明：M1代花粉在形状上出现了畸形、皱缩和空洞等性状的变化;与对照相比,M1代花粉比对照要小,差异达到极显著水平;M1代花粉活性降低,与对照存在显著差异;并且在M1代中发现一株花粉半不育的单株。

| Abstract: | The main botany and palynology traits of SP1 generation were observed and analyzed after seeds of Xunhua line pepper carried by the satellite"practice on the 8th".The results showed as follows:variation range and coefficient of variation of height, stem diameter, leaf length and leaf width of SP1 generation by Satellite-carried were higher than CK. Palynology traits of SP1 generation and CK were studied and showed that the pollen shape of SP1 generation had some changes such as abnormality, crimple and empt... |
