摘要: 比较了不同体积分数茶树油处理橡胶树Hevea brasiliensis割线对橡胶产量和产排胶生理特性的影响，并与体积分数为0.5%乙烯利处理作了比较。结果表明：与对照比较，用体积分数为80%和100%茶树油涂抹割线可增加胶乳产量并使橡胶树的产排胶生理特性发生较大变化，其中镁离子和无机磷极显著增加（P＜0.01），硫醇降低。体积分数为100%茶树油与体积分数为0.5%乙烯利处理的增产效果相当，但前者的干胶和蔗糖极显著高于后者（P＜0.01），而硫醇则显著低于后者。茶树油刺激增产的机制可能有别于乙烯利刺激增产理论。表3参13Abstract: To examine the effects of tea tree oil on rubber latex yield and the resulting latex physiological parameters of rubber tree （Hevea brasiliensis），clean water and 20%，40%，60%，80% and 100% of tea tree oil were applied on the tapping cut of rubber trees. The data were analyzed by Duncan test and its results showed that when compared to clean water （ck），80% and 100% of tea tree oil stimulation significantly promoted rubber latex yield（P＜0.05）. In addition，the latex physiological parameters changed with the sucrose content（P＜0.01），magnesium ion content （P＜0.01） and inorganic phosphorus content （P＜0.01） of latex significantly increasing and thiol content significantly deceasing （P＜0.01）. The effect of tea tree oil treatments on rubber yield was similar to the impact of 0.5% ethrel stimulation. However，compared to ethrel stimulation，100% tea tree oil treatment significantly increased dry rubber and sucrose contents （P＜0.01） and decreased thiol content （P＜0.01）. Thus，tea tree oil treatment involved different latex yield promotion mechanisms than that of ethrel stimulation. ［Ch，3 tab. 13 ref.］
