摘要: 2018年5月15日和7月9日取田间樱桃李新梢茎段,用酒精和次氯酸钠灭菌,无菌茎芽在含有不同浓度IBA的培养基上增殖,在黏壤土支撑的培养基中生根,然后移栽。结果表明,不同时间取材的灭菌效果无显著差异,污染率均低于10%,萌芽率均达100%;酒精浸泡后用无菌水冲洗与否对灭菌效果无明显影响;樱桃李试管苗在含有0.4 mg/L IBA的1/2MS培养基上培养60 d后的繁殖系数为4.2;在黏壤土做支撑物的培养基上的生根率为68.8%,显著高于琼脂培养基上的生根率;土壤支撑培养的樱桃李试管苗的移栽成活率为75.0%,显著高于琼脂支撑培养的试管苗的移栽成活率(33.3%)。本试验结果将为完善樱桃李组织培养快速繁殖技术提供依据。

Abstract: The stem sections were taken from new shoots of Prunus cerasifera which grew in field on May 15th and July 9th in 2018 respectively and were sterilized with alcohol and sodium hypochlorite. The sterile stem buds were proliferated on medium containing different concentrations of IBA, rooted in soil supporting medium, and then the plantlet were transplanted. The results showed that there was no obvious difference in the sterilization effect of the samples at different time, and the contamination rate was less than 10% and the germination rate was 100%. There was no obvious different effects between washing and no-washing by sterilized water after soaked in alcohol on sterilization. The propagation coefficient of the plantlet of Prunus cerasifera was 4.2 in 1/2MS medium added with 0.4 mg/L IBA when cultured for 60 day. The rooting rate of the plantlet of Prunus cerasifera cultured in soil supporting medium was 68.8%, which was obviously higher than that of the plantlet cultured in agar medium. The survival rate of the plantlet of Prunus cerasifera transplanted in soil supporting medium was 75.0%, which was obviously higher than that of plantlet in agar medium(33.3%). These results can provide basis for improving rapid propagation technique of Prunus cerasifera.
