摘要

盆栽3年生愛文檬果枝條於花期去頂後，葉腋側芽可分化成正常的花序、混合花序與新梢等三種類型。在溫室高溫生長下(21.9℃)新梢出現的機會較高；在戶外自然生長下(18.6℃)，正常花序出現率較高。
盆栽2年生海頓檬果在花期新梢葉腋之花序，於生長箱日／夜溫17/10℃之條件下，生殖生長漸趨旺盛，新梢上葉腋小花序漸漸擴張，葉片陸續脫落而轉變成正常花序。在32/25℃的生長條件下，則營養生長漸趨旺盛，新梢上葉腋的小花序漸漸萎縮脫落，而轉變成新梢。

並列摘要

During flowering period, the decapitated 3yr old potted Irwin mango showed three types of growth in axil-normal flower inflorescence, mixed Panicle and new shoots. High rate of new shoots appeared under high temperature (21.9℃) in greenhouse, and normal flower inflorescence predominated under lower temperature (18.6℃) outdoors.
Controlled growth chamber study showed that potted Haden mango under 17/10℃ had prosperous reproductive growth, with expanding inflorescence branch, and gradually declined leaves on panicle. Whereas, under 32/25℃, it showed more active vegetative growth, with inflorescence degenerated and new shoots developed instead.
