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 mg/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 different 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.
目的
探索金樱子扦插繁殖的最佳植物生长调节剂及其适宜浓度。
方法
将插穗用6种植物生长调节剂（吲哚乙酸、吲哚丁酸、萘乙酸、多效唑、2,4-二氯苯氧乙酸和生根粉）在不同浓度（100、200和500毫克/升）下处理50秒。生长30天后，通过方差分析和多重比较，找出金樱子最适宜的扦插繁殖方法。
结果
在相同条件下，不同种类植物生长调节剂的不同浓度对金樱子扦插繁殖的影响不同。一般来说，用200毫克/升多效唑浸泡50秒的插穗效果最佳，其增效指数和平均根数较高（12.42）；用200毫克/升吲哚丁酸浸泡50秒的插穗也有显著效果，增效指数次之，成活率最高（96.67%）。
结论
200毫克/升多效唑能最佳地促进金樱子的扦插繁殖。
