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。
Taking early indica “Guangluan 4” as test material, Na_2 ~ (14) CO_3 and ~ (14) CO_2 as mutagen, M_2 generation rate, plant height and sterile plant mutation rate were investigated. The effect of ~ (14) C on rice mutagenicity and its relationship with different treatment methods was studied by using root immersion, foliar spraying, base injection of plant and ~ (14) CO_2 photosynthesis in Na_2 ~ (14) CO_3 solution The results showed that the mutation rates of precocious, dwarf and sterile plants were all highest when Na_2 ~ (14) CO_3 solution was introduced by the plant base injection method, followed by the spraying of Na_2 ~ (14) CO_3 solution and The photosynthesis method was used to introduce ~ (14) CO_2, and the lowest mutation rate was achieved by Na_2 ~ (14) CO_3 liquid immersion.
