绞股蓝引种扦插试验

Introduction and Cuttage Experiment of Gynostemma pentaphyllum

试验采用陕西平利五叶、七叶两种品种,涉及扦插部位(嫩枝、老枝)、蔓节、覆膜与否、药物处理浓度4个因素的单因素对比试验。试验结果表明,老枝的成活率明显优于嫩枝;扦插覆膜(F组)的情况下长势稍好于不覆膜(CK组)处理。但是影响并不是很大;α-萘乙酸的浓度越高,生根数越多。α-萘乙酸的浓度对绞股蓝长势影响不显著。3种处理中α-萘乙酸浓度300cc时,绞股蓝长势最好。绞股蓝7个处理之间的蔓长、根长、根数存在极显著差异。

The experiment was carried out with five-leaf and seven-leaf varieties from Pingli county of Shanxi,by comparing the 4 factors of cutting sites（ twigs,old branches）,number of knots,mulching film and drug concentration. The results showed that the survival rate of the old branches was significantly higher than that of twigs. In the case of cuttage with mulching film（ F group）,the growth potential was slightly better than that of no-film-covered（ CK group）; The higher the concentration of α-NAA,the larger the rooting number. Concentration variation of α-NAA showed no significant influence on the growth of Gynostemma pentaphyllum. When the concentration of α-NAA was 300 cc,the growth was the best.There were significant differences respectively in vine length,root length and root number of 7 groups.
