摘要

溫度是影響檬果開花結果原因之一，在10月初控制盆栽二年生檬果苗（愛文／本地種）的給水量，於12月下旬則萌發新梢，翌年l月16日將之分成二組，一組置室外，一組搬入溫室內，1月30日開始新梢葉腋陸續萌出花序，至2月20日室外之植株（試驗期間溫度變化爲11.9~18.8℃，平均14.5℃）萌花率達90%；但溫室內（15.6~28.5℃，平均19.3℃）萌花率僅40%。
開始着果後36天（3月12日～4月16日），溫室內（溫度變化20.2~32.9℃，平均24.7℃）植株之結果率僅25%；而室外（17.7~24.8℃，平均20.6℃）結果率可達56%，但果實生長、發育與成熟的速度均以在溫室內生長者最爲迅速。

Temperature is one of the factors influencing flowering and fruiting in mango. After new shoots sprouting at the end of December, the two-year-old potted mango plants (Irwin/local variety), under controlled water supply, were divided into two groups on January 16th-one remained outside, another removed in to greenhouse. From late January, inflorescence appeared in the axil of new shoots. Up to February 20th, the percentage of inflorescence emergence reached 90% in outdoors (temperature ranging between 11.9 and 18.8℃, with 14.5℃ in average) compared to 40% in greenhouse (15.6~28.5℃ 19.3℃ in average).
Thirty-six days after fruit set starting on March 12, the percentage of fruit set towered to 25% in greenhouse (temperature ranging from 20.2 to 32.9℃ with average of 24,7℃) in contrast to the 56% outdoors (17.7~24.8℃, 20.6℃ in average). However, the growth and development of fruits were more rapid in greehouse.
