摘　　要：探讨了环割促进龙眼成花的生理机制 ,包括处理对树体内源激素和营养水平的影响。结果表明 ,环割处理提高了花芽生理分化期和花序原基形成期芽内的 i PA和 ABA含量 ,降低了GA1/3的水平 ,改变了内源激素及其平衡。同时 ,提高了叶片淀粉和总糖含量及 C/N比值。环割促进了龙眼成花 。The research studied the mechanism of ringing treatment promoting flower differentiation in longan fruit trees, including effects on the changes of endogenous hormones and nutrition levels. The results were as follows: ringing treatment increased levels of iPA and ABA, inhabited GA 1/3 activity, and changed their balance. It significantly increased total leaf carbohydrate and starch contents, C/N ratios in leaves. Ringing treatment was beneficial to increase flowering rate and fruit set rate.
