摘要

在桃李栽培上可利用氰胺（hydrogen cyanamide）或益收生長素（Ethrel，ethephon）促進萌芽、開花而提早產期。益收生長素可延遲萌芽，而防止晚霜之為害；利用萘乙酸及其鈉鹽（NAA，Na-NAA）、益收生長素及加保利（賽文，Sevin，carbaryl）等可進行疏花疏果以節省人工疏果勞力；利用生長抑制劑如亞拉生長素（Alar，daminozide）、克美素（CCC，Cycocel，chlormequat）、益收生長素及paclobutrazol等可以抑制植株之徒長，促進花芽分化，並能減少冬季修剪量；利用細胞分裂素（cytokinins）以及勃激素（gibberrellins）能促使果實肥大，提高果實品質。

並列摘要

Many plant growth regulators can be used on culture of peach and plum. Hydrogen cyanamide or ethephon can promote bud break and flowering, so the ealier harvesting can be done. Ethephon delays bud break and also avoiding the damage of frost. NAA, Na-NAA, ethephon and carbaryl are used in flower thinning so the save the labor. Growth inhibitors as Alar, Cycocel, ethephon and paclobutrazol inhibit shoot growth and promote flower bud differentiation, and then the pruning labor were lowered. Cytokinins and gibberellins promote fruit enlargement and enhance fruit quality.
