NAA与营养液浓度对鹅掌柴根系及枝叶生长的影响

摘要： 采用水培技术对鹅掌柴[Schefflera octophylla（Lour.） Harms]的根系进行快速诱导和枝叶生长研究,用不同浓度的NAA和营养液对鹅掌柴枝条进行处理,通过试验统计和方差分析得出水培鹅掌柴的根系生长的最适NAA和营养液浓度,其最适根系生长的NAA浓度为15 mg/L,最适营养液浓度为200~300 mg/L,即为1/4配方标准液;水培鹅掌柴根系诱导成功后,在水培鹅掌柴后期生长及养护过程中,营养液浓度为500~600 mg/L,即为1/2配方标准液时,水培鹅掌柴的根系最发达且植株的枝叶最茂盛。说明,同一生长调节剂、同一营养液不同浓度下对水培鹅掌柴的影响存在较大差异。

Abstract: Rapid induced the root and branches by hydroponics technique, with different concentrations of NAA and nutrient solution to treat the branches of Schefflera octophylla （Lour.） Harms, and the optimal concentration of NAA and nutrient solution for its root growth were obtained by means of experimental statistics and variance analysis, namely the optimal concentration of NAA was 15 mg/L, the optimal concentration of nutrient solution was 200~300 mg/L（about 1/4 of mother liquid）. After induced successful, the roots and branches were most developed when nutrient solution concentration was 500~600 mg/L（about 1/2 of mother liquid）. So, the same hormone and the same nutrient solution on the Schefflera octophylla （Lour.） Harms varied greatly at the different concentration.

Key words: Schefflera octophylla （Lour.） Harms, hydroponic, NAA, nutrient solution
