不同浓度生根粉对矾根扦插生根的影响

Effects of Different Concentrations of Rooting Powders on Cuttage Rooting of Heuchera micrantha

为了探讨不同浓度生根粉对几种矾根扦插生根的影响,为矾根的扦插繁殖提供参考,选择狂野、莱姆里奇、黄桃派、乔治亚桃子4个矾根品种,分别将不同品种的矾根叶柄用500、1750、3000 mg/L 3种生根粉浓度处理,并对生根情况进行分析。结果表明,不同浓度生根粉对矾根生根作用效果不同。适宜狂野扦插的生根粉浓度为1750 mg/L,生根粉对其生根率提高作用不大;适宜莱姆里奇扦插的生根粉浓度为3000 mg/L,其生根率会随着生根粉浓度的提高而有略微提高;适宜黄桃派扦插的生根粉浓度为3000 mg/L,生根粉的浓度越高,对其生根的促进作用越大;适宜乔治亚桃子扦插的生根粉浓度为500 mg/L,低浓度生根粉对其生根的促进作用较大。

In order to explore the effects of different concentrations of rooting powders on the cuttage rooting of several Heuchera micrantha varieties,and provide some references for the cuttage propagation of Heuchera micrantha,four kinds of cultivars(Kuangye,Liam Ritchie,Peach Pie and Georgia Peach)were selected and treated on the leaf stalk with 500,1750,3000 mg/L rooting powders respectively,and the cuttage rooting of Heuchera micrantha was analyzed.The results showed that the different concentrations of rooting powder had different effects on Heuchera micrantha rooting.The suitable rooting powder concentration for Kuangye was 1750 mg/L,and the promoting effect of rooting powder on the rooting was little.The suitable rooting powder concentration for Liam Ritchie was 3000 mg/L,and the rooting rate increased slightly with the increase of rooting powder concentration.The suitable rooting powder concentration for Peach Pie was 3000 mg/L.The higher the concentration of rooting powder,the greater the promoting effect on the rooting.The suitable rooting powder concentration for Georgia Peach was 500 mg/L,and the low concentration of rooting powder had greater promoting effect on the rooting.
