摘要

本省檬果栽培之首要問題為產期過於集中，為分散產期可應用提早產期及延後開花之方式。在應用抑制檬果營養生長，促進花芽形成提早開花方面，Ethrel、Alar、CCC及MH都有效果，但其效果常因植株樹勢、品種及氣候因素等而不易掌握。一種新開發的生長抑制劑paclobutrazol被應用於檬果，發現抑制效果甚佳，可以提早開花及採收約3個月，繼續之試驗正進行中。而在延後檬果產期方面，除了摘除花穗促成再生腋花穗而延開花開期外，GA_3也被應用於延遲開花處理，但其適用劑量則需深入探討。

The harvest season of mango in Taiwan is concentrated between May and September. There are two ways extend the harvest duration, one is to enhance floweing for earlier harvest and the other is to delay flowering. To inhibit vegetative growth and enhance fower bud formation, the application, the application of Ethrel, Alar, CCC and MH give positive effects, but the results depend on the tree vigor, variety an climate condition, and it is difficult to control. The application of paclobutrazol on mango gave an excellent inhibitive effect which got a harvest of 3 months earlier. To delay harvest of mango, the de-blossoming technique induce the axillary flower buds, and GA3 treatments also delay flowering but the proper dosage needs further experiment.
