摘要:

自1957年到1960年曾三次用秋水仙精处理小麦——黑麦杂种第一代的分蘖苗,获得小黑麦品系712个。秋水仙精用0.05%及0.04%水溶液,处理时间四天。在处理后的成活植株中,处理成功的植株,三次总平均占40.8%。根据资料分析的结果,由直接受到处理影响的腋芽所长成的一次分蘖有30%的成功率,而由一次分蘖上所长出来的未直接受到处理影响的二次分蘖则只有10%的成功率。如能促使处理后恢复的植株尽可能多地产生一次分蘖,使每一单株都具有6—7个以上穗子,这样,以株为单位的处理成功率估计至少还能增加15%。

Abstract:

From 1957 to 1960,colchicine aqueous solution has been used for doubling the number ofchromosomes in wheat-rye F_1 hybrids.The concentrations of colchicine used for treatmentwere 0.04% and 0.05%.Hybrid seedlings were exposed in colchicine solution for 4 days inroom temperature not over 15℃.After the treatment,the seedlings were transplanted ingreenhouse where a condition of high humidity and comparatively low temperature (usuallybelow 10℃) was maintained until the seedlings had recovered from colchicine poi...
