余甘子冬季嫁接技术试验

Experiment of Phyllanthus emblica by Grafting in Winter

为便于云南元谋干热河谷区冬季余甘子资源收集和完好保存种质遗传特性,需要用当即嫁接保存的方法,但冬季气温低,嫁接成活率低,不能满足需求。试验表明,采用冬季人工辅助增温、保温设施能大幅提高余甘子嫁接成活率,可满足余甘子资源收集和保存的要求,同时还缩短了研究周期。

For the need of collection, conservation and study on germplasm resource of Phyllansthus emblica in Winter, experimentof grafting was conducted in the dry and hot valley of Yuanmou, Yunnan Province. The results showed that the survivalrate would increase greatly when heating or heat preservation by man in Winter. This can both meet the demand of germplasmcollection and conservation and shorten the study duration.
