摘要
目的:筛选适合金樱子扦插繁殖的植物生长调节剂及其适宜浓度。方法:采用不同浓度(100、200、500mg/L)的6种植物生长调节剂(吲哚乙酸、吲哚丁酸、萘乙酸、多效唑、2,4-二氯苯氧乙酸、生根粉)分别对金樱子一年生枝条50 s浸泡处理,经过30 d的生长后,调查其存活率、生根率、平均生根数、平均根长、最长根长等生长指标,并进行方差分析和多重比较。结果:6种生长调节剂不同浓度对金樱子扦插繁殖的影响不同,以200 mg/L多效唑处理浸泡50 s的各指标显著高于对照组,其扦插促进作用综合效果最好,且平均根数最多(12.42条/枝);200 mg/L吲哚丁酸处理浸泡50 s的各指标亦显著高于对照组,促进作用综合效果居次,而存活率最高(96.67%)。结论:200 mg/L多效唑浸泡金樱子50 s扦插繁殖综合效果最好。
Objective ： To explore the optimal plant growth regulator and its suitable concentration for the cutting propagation of Rosa laevigata. Methods ： The cuttings were dealt with 6 kinds of plant growth regulators （ IAA, IBA, NAA, PP333,2,4-D and ABT） at different concentrations（ 100,200 and 500 rag/L）for 50 seconds. After 30 days growth ,by analysis of variance and multiple comparisons ,the most suitable cutting propagation method for Rosa laevigata was found. Results ： Under the same condition, different concentration of dif- ferent kinds of plant growth regulators had different effects on cutting propagation of Rosa laevigata. Generally speaking, cuttings soaked with 200 mg/L PP333 for 50 seconds was the best, with the high multiple effectiveness index and average root number（ 12.42 ） ;Cuttings soaked with 200 mg/L IBA for 50 seconds also had significant effects ,with the second high multiple effectiveness index and the highest survival rate（ 96. 67% ）. Conclusion ：200 mg/L PP333 can promote cutting propagation of Rosa laevigata best.
