在苏联科学院化学物理学研究所,对卵形·蓝色李和早熟李两品种的绿枝插条和木质化插条以及樱桃李类型21和11—116的发芽种子、绿枝插条和木质化插条用化学诱变剂进行了处理。处理时使用浓度为0.012、0.025、0.050%的亚硝基乙脲水溶液和浓度为0.005、0.010、0.020%的硫酸二甲脂水溶液。处理时间为15小时。研究结果表明,供试的诱变剂对李的绿枝插条存活率有明显影响。例如,卵形·蓝色李在0.005%的硫酸二甲脂和0.012、0.025%的亚硝基乙脲处理后,其绿枝插条存活率分别为12.5%和25.0%(对照为16%),更高的诱变剂浓度为致死量,早熟李的绿枝插条对硫酸二甲脂和亚硝基乙脲的
At the Institute of Chemical Physics, USSR Academy of Sciences, green shoot cuttings and lignified cuttings of both oval-blue-plum and precocious plum varieties, as well as germinated seeds of cherry plum types 21 and 11-116, green shoot cuttings and wood The cuttings were treated with chemical mutagens. The nitrosure solution of nitrosurea at concentrations of 0.012, 0.025 and 0.050% and the aqueous solution of dimethyl sulfate at concentrations of 0.005, 0.010 and 0.020% were used for the treatment. Processing time is 15 hours. The results showed that the mutagens tested had a significant effect on the survival rate of Li’s green shoots. For example, the survival rate of green-leaf cuttings of oval-blue plum was 12.5% and 25.0% (control: 16%) after being treated with 0.005% dimethyl sulfate and 0.012,0.025% , Higher mutagen concentration for lethality, precocious plum green shoot cuttings on dimethyl sulfate and nitrosourea
