广西特色香蕉“桂红蕉1号”快速繁殖技术研究

The Rapid Propagation Technology Research of Guangxi Characteristic Banana Guihongjiao No.1

为加快广西自主选育香蕉品种“桂红蕉1号”的推广应用,针对传统香蕉品种在组培生产过程中变异率高的问题,通过室内和田间试验开展外植体获取、继代培养、生根培养、炼苗等组培快繁技术研究。综合比较发现,无害化处理的木薯渣或甘蔗渣与椰糠配比的育苗基质更为理想,在培养最后1代继代苗时,采用聚丙烯袋代替传统培养瓶作为培养容器能有效降低生产成本。该研究表明这一套优化后的快速繁殖技术具有应用于香蕉种苗繁育的巨大潜力。

In order to speed up the popularization and application of the self-selected banana variety Guihongjiao No.1 in Guangxi,aiming at the problem that the variation rate of the traditional banana variety was high in tissue culture production process,the research and development of tissue culture and fast propagation technology were carried out,such as explant acquisition,subculture,rooting culture,and mixing seedling,through laboratory and field experiments.The results showed that the mixture of cassava slags and bagasse with coconut bran was more ideal,and the production cost could be effectively reduced by using polypropylene bags instead of traditional containers in the last generation of seedlings.This study showed that this optimized rapid breeding technology had great potential for banana seedling breeding.
