摘　　要：为探讨"园丰素"(其有效成分是芸苔素内酯)对油茶(Camellia oleifera)生长状况及生理的影响,进行"园丰素"喷施试验。结果表明:"园丰素"对不同品系油茶影响不同,长林27号对预设的各"园丰素"浓度不敏感,而喷施"园丰素"能使长林53号和长林166号生物量增加,光合作用加强,当"园丰素"中芸苔素内酯浓度为0.33mg/L时喷施有利于春梢生长并能提高叶面的光合速率;当"园丰素"中芸苔素内酯浓度为0.20mg/L时喷施有利于秋梢生长,当"园丰素"中芸苔素内酯浓度为0.25mg/L时喷施能提高油茶产量,生产实践中应根据所经营目标和油茶不同生长阶段选择合适浓度。In order to approach the effects of Yuan fengsu（BRs is the active ingredient） on the physiological characteristics and growth of Camellia oleifera the test on Yuanfengsu being spray was studied.The following is the results： Yuanfengsu tested on different strains of Camellia oleiferas had different effects.Changlin 27 was insensitive to all concentrations in these tests;Yuanfengsu not only increased the biomass of both Changlin 53 and Changlin 166 ,but also enhanced photosynthesis.The concentration of 0.33 mg/L of BRs in Yuanfengsu was beneficial to the growth of the spring branches and increased the photosynthetic rates of leaves.The concentration of 0.20 mg/L was beneficial to the growth of the fall branches.The concentration of 0.25 mg/L could increase the production of the Camellia.The right concentration of Yuanfengsu should be selected according to the aim of practical management of Camellia oleifera and diffent growing stages.
