航天搭载菊苣种子的生物学特性研究

摘要

Dry seeds of Cichorium intybus were carried by return satellite for space mutagenesis.The space effects on characteristics of chicory SP1,including the germination capacity ability,vigour of germination,the growth of seedlings? main root length,and agronomiv characteristics in the field,were analyzed after space mutagensis.There were significant differences between both chicories and their ground controls.SAG0002 was better than SAG0001.Except for individual characters,the biological effect on different varieties of chicory was significantly promoted.%利用返回式卫星搭载菊苣种子进行空间诱变处理,对航天搭载的2份菊苣SP1代群体的生物学特性进行了分析,主要包括发芽率、发芽势、幼苗生长、田间农艺性状等.结果表明,2份菊苣的生物学特性有一定的差异,SAG0002材料表现优于SAG0001,但除个别性状外,航天搭载从总体上对地上部性状起到一定的促进作用.
