摘要:
为了深入研究植物空间诱变育种，比较经返回卫星搭载的蒙农杂种冰草干种子与未经搭载的对照种子细胞有丝分裂指数、细胞核畸变、染色体行为。结果表明：空间诱变促进了冰草种子根尖核畸变的产生，其中以单微核为主；空间诱变还导致其染色体畸变。
Abstract:
 In order to study the space mutation breeding of plants further,the mitosis index,nuclei distortion and chromosome action of Mengnong hybrid Agropyron seed carried by recouerable sateuite launch were compared with seed which were never carried.The results showed that space mutagenesis promoted the nuclear distortion of root produced,single micronucleu was the main variation type;space mutagenesis led to chromosome aberration.
