摘要: 为探索不同浓度植物生长调节剂对翅茎白粉藤(Cissus hexangularis)扦插生根的影响,促进其大量扦插繁殖。以一年生翅茎白粉藤枝条为试验材料,用不同浓度的NAA(萘乙酸)、IAA(吲哚乙酸)、ABT(生根粉)3种生长调节剂对翅茎白粉藤插穗预处理后进行扦插,60 d后测定插穗生根率、单株生根数、最长根长、可溶性糖含量、可溶性蛋白质含量和过氧化物酶(POD)活性。结果显示,3种生长调节剂均对翅茎白粉藤扦插繁育有促进作用,不同浓度生长调节剂对赤茎白粉藤扦插生根综合评定,最适浓度为ABT 100 mg/L、IAA 400 mg/L、NAA 100 mg/L,浓度高于最适浓度,促进扦插生根效果减弱。

Abstract: In order to explore the effects of different concentrations of plant growth regulators on the cutting rooting of Cissus hexangularis, and to promote a large number of cutting propagation.The annual branches of Cissus hexangularis were used as experimental materials, and three growth regulators of different concentrations NAA, IAA and ABT were used to pretreat the cuttings of Cissus hexangularis. After 60 days, the rooting rate of cuttings, rooting number per plant, the longest root length of adventitious root, contents of soluble sugar, contents of soluble protein and peroxidase (POD) activity were measured. The results showed that all the three growth regulators could promote the cutting propagation of Cissus hexangularis. The comprehensive evaluation of cutting rooting of Cissus hexangularis with different concentrations of growth regulators showed that the optimum concentrations of ABT 100 mg/L, IAA 400 mg/L and NAA 100 mg/L were higher than the optimum concentration, which weakened the cutting rooting effect.

Key words: Cissus hexangularis, rooting of cuttage, growth regulator, physiological index
