Abstract
本試驗是以誘導檬果(Mangifera indica L.)產生不時花不時果爲目的，2年生愛文檬果共75株於花期過後，從3月至5月間每隔1個月用修剪掉半數著果的花序，使產生不同枝齡的新梢以供處理每次修剪25株。在8月下旬以Alar, Cycocel, Ethephon, Maleic hydrazide等各種植物生長抑制劑及硝酸鉀，每隔7天全株噴灑1次，每種藥劑處理共計15株，連續處理5次，皆無法誘致檬果新梢與不時花的產生。The primary purpose of this study was to induce flowering for production of off-season ”Irwin” mango fruits. Half of the total fruit set panicles from 75 two-year old trees were prunned from March to May once per 25 trees per month to induce new shoots of different age for spray treatments. The 5 growth regulators of alar, cycocel, ethephon, maleic hydrazide and sodium nitrate were used in experiment. The spray was done in late-August with 15 plants per treatment, repeated for 5 times at a 7 day interval. No treatmen could induce any new shoot or off-season flowering during high temperature period.
