| 摘 要： | 以不同收获年份的小麦-中间偃麦草部分双二倍体种子为试材,研究了室温保存条件下,种子活力变化与遗传完整性。结果表明,随贮存时间的延长,种子发芽率呈下降趋势,贮存11年、12年的种子基本失去活力,贮存7年的种子平均发芽率仅为13.36%。鉴定还发现,保存7年的小麦-中间偃麦草部分双二倍体中5根尖染色体畸变率高达35.09%。

| Abstract: | Seeds of Triticum aestivum-Thinopyrum intermedium partial amphiploid were used to investigate the germination activity changes and genetic integrality in their preserve course at room temperature.The results showed: the germination index and activity index of the seeds decreased as the holding time extension.Seeds stored for eleven or twelve years could not burgeon.The average rate for seed germination was 13.36% by storage seven years.35.09% chromosome aberration was observed in root cells of conservation seven years seed of Triticum aestivum-Thinopyrum intermedium partial amphiploid 5. |
