为了探索食用玫瑰快速繁殖技术，选取食用玫瑰滇红一年生插条为实验材料，研究不同浓度的激素对扦插生根的影响及生根过程中过氧化物酶（POD）和多酚氧化酶（PPO）活性变化规律。结果表明：插条经过400 mg?L‐1 IBA 处理后插条生根率达最高，为70％。 POD 活性在愈伤期持续升高，20 d 达第一个高峰，且经激素处理过的插条 POD 比对照先达高峰，之后下降再上升，40 d 达第二个高峰后下降；PPO 在不定根诱导期一直上升，30 d 到达最高点，之后下降。
Research on the Cutting Propagation Techniques for Rusa rugosa Dianhong
In order to explore rapid reproduction technology of edible rose ,taking the rosa rugosa Dianhong an‐nual cutting as experimental material ,the effect of different concentration hormones on cutting rooting and the change in activities of peroxidase(POD) and polyphenol oxidase(PPO) in the rooting process were studied .The results showed that 400 mg?L‐1 IBA marked the best rooting rate for 70% .The POD activity increased in callus formatting and reached first peak at the 20th day .The cutting by hormone‐treated first reached peak than con‐trol ,it showed down‐up and reached the second peak at 40th day ,and then decreased .The activity of PPO had been increased in root inducing ,reached the highest point at the 30th day ,then decreased .
