摘要
以早籼“广陆矮4号”植株作试验材料,Na_2^(14)CO_3和^(14)CO_2作诱变剂,M_2代熟期、株高和不育株突变率作为考察指标,研究了^(14)C对水稻的诱变效应与不同处理方法的关系.对Na_2^(14)CO_3溶液用浸根、叶面喷施、植株基部注射和^(14)CO_2用光合作用引入植株等四种方法比较试验结果:早熟、矮秆和不育株突变率均以植株基部注射方法引入Na_2^(14)CO_3溶液处理最高,其次是用喷施方法引入Na_2^(14)CO_3溶液和用光合作用方法引入^(14)CO_2两个处理,用Na_2^(14)CO_3液浸根方法处理突变率最低。
Relationships between mutagenic effects and treating methods of rice plants by ^(14) C were studied with early indica rice 'Guanluai 4' as test material and mutagens of Na_2^(14) CO_3 and ^(14) CO_2.The mutation rates of heading date, plant height and sterile plant were observed in M_2.The results of comparative experiments of 4 methods (Na_2^(14) CO_3 solution introduced into plants by root immersing, spraying on leaves, injection at plant bases and ^(14) CO_2 introduced into plants by photosynthesis) showed that the highest mutation rates of all early-maturing, drawf-stem and sterile plant resulted from the treatment by injecting Na_2^(14) CO_3 solution into plants at baese, and then from the treatments by spraying Na_2^(14) CO_3 solution on leaves and introducing ^(14) CO_2 into plants by photosythesis.The lowest mutation rates came from the treatment by root immersing in Na_2^(14) CO_3 solution.
