摘要
桃树进行多效唑土施和叶面喷施后，叶片变小变厚，蒸腾速率降低，光合速率提高；当年新梢生长量和干周增量明显减少。土施较叶面喷施效应更显著。
Smaller and thicker leaves with dark green in color,lower transpiration and higher photo-synthesis(Pn)rates were observed in the peach trees( P. persica cv Yuhualu)treated with Pa-clobutrazol(PP333),either by root drenching or leaf spraying,Shoot growth and trunck circleincrement were significantely reduced ,-plus a substantial control in watersuckers. Root drenchingshowed stronger effects than that of leaf sraying in the investigated issues.
