不同生根剂对圆叶福禄桐扦插效果的影响

目的]探讨适合圆叶福禄桐扦插的生根剂及浓度.方法]开展IBA、NAA和根太阳3种生根剂在不同浓度时对圆叶福禄桐扦插生根效果的研究.结果]各个处理的综合排名次序为NAA-400 mg/L,NAA-100 mg/L,IBA-200 mg/L,根太阳200 mg/L,IBA-400 mg/L,IBA-100 mg/L,根太阳-400 mg/L,NAA-200 mg/L,CK,根太阳-100 mg/L.结论]通过对试验结果进行多重分析和综合评价,当NAA生根剂浓度为400 mg/L时,圆叶福禄桐扦插枝条的综合生长情况达到最优;当NAA生根剂浓度为100 mg/L时,综合排名位居第2,但成活率高于400 mg/L浓度处理.

Effect of Different Rooting on Cutting of Polyscias balfouriana

Objective] The rooting reagent and concentration which was suitable for cutting were discussed.Method] Through 3 types of rooting reagent,i.e.IBA,NAA and diethyl aminoethyl hexanoate AC,to study their effects on cottage rooting of Polyscias balfouriana.Result]It showed that the rankings for processing were as follows：NAA-400 mg/L,NAA-100 mg/L,IBA-200 mg/L,Gen taiyang 200 mg/L,IBA-400 mg/L,IBA-100 mg/L,Gen taiyang-400 mg/L,NAA-200 mg/L,CK,Gen taiyang-100 mg/L.Conclusion] The growth of cutting to achieve the optimal condition of Polyscias balfouriana by multiple analysis and comprehensive evaluation of experimental resuhs,when the concentration of NAA was recommended as 400 mg/L.When NAA was 100 mg/L,the comprehensive ranking of Polyscias balfouriana was second,but the survival rate of cutting was higher than the concentration of 400 mg/L.
