摘  要:
裸果木(Gymnocarpos przewalskii Maxim)属国家二级珍稀保护植物,为了更好保护这一珍稀濒危植物资源,以插穗类型、扦插基质、ABT处理为试验因素,进行了L9(34)正交扦插育苗试验。结果表明:二年生枝条最适宜扦插育苗;扦插基质以沙土为最佳;ABT溶液浸泡插穗对成活率影响显著,最佳组合水平150mg/L,成活率达到80%。此外,试验环境因素对裸果木幼苗的成活率影响也较大。

摘  要:
Taking cutting types, cutting substratum, ABT treating as experiment factors, L9(34) orthogonal experiment on cutting and breeding of Gymnocarpos przewalskii has been done. The results showed that two-year-old cutting was most suitable for breeding. Sandy soil was the best substratum, 150 mg/L was the optimum concentration of ABT, with which, the survival ratio of seedlings reached to 80 %. In addition, experimental environment could also influence the survival ratio of Gymnocarpos przewalskii seedlings.
