| 摘 要： | Objective] It aimed to find an optimum condition for compensatory growth of peony.Method] The different defoliation intensies and frequencies of penoy were implemented to observe accumulated aboveground biomass, regenerated bud number,stem-leaf ratio and the chlorophyll concentration change in residual leaves.Result] When the defoliation frequency was conducted every 20 d once and defoliaton intensity was from 40%-60%,the accumulated biomass was biggest, when the defoliation frequency was conducted every 10 d once and defoliation intensity was from 60%-80% the regenerated bud number was maximum.The stem-leaf ratio of mild and moderate defoliation intensities(20%-60%) was significantly lower than that of control group.When the defoliation frequency was conducted every 20 d once and defoliation intensity was from 40%-60%,the chlorophyll concentration in residual leaves was obviously higher than that of control group.Conclusion] The proper defoliation intensity(60%) and lower defoliation frequency(defoliation was conducted every 20 d once) were most favorable to the growth and regenerated of peony which was the compensatory growth.
