梨樹的生育情形影響果實產量與品質,並決定於栽培技術之優劣,適當的使用植物生長調節劑是提昇栽培技術的途徑之一。本文介紹使用於梨樹各生長階段的植物生長調節劑之用法及使用結果,這些製劑包括萘乙酸及其鈉鹽(NAA,Na-NAA),吲哚丁酸(IBA)、勃激素(GA)、細胞分裂素(cytokinins)、克美素(CCC)、亞拉生長素(Alar)、益收生長素(Ethrel)、氰胺(hydrogen cyanamide)及paclobutrazol等。
The quality and yield of pear fruits was affected by the tree's growth condition following orchard management. One of the approachs to promote management level was by properly application of plant growth regulators (PGRs). The application and results of some PGRs that were practically used on different growth stages of pear trees was reviewed briefly here. These PGRs include NAA, Na-NAA, IBA, GA, CCC, cytokinins, Alar, Ethrel, hydrogen cyanamide, paclobutrazol, and etc.
