Abstract
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1月16日將之分成丰組，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（試瞼期間溫度變化為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%。
開始著果後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（l7.7~24.8℃，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為迅速。
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 t o February 20th, the percentage of inflorescence emergence reached 90% in outdoors (temperature ranging between 11.9 and 18.8°C, with 14.5°C in average) compared to 40% in greenhouse (15.6~28.5°C, 19.3°C in average).
Thirty-six days after fruit set starting on March 12, the percentage of fruit set lowered to 25% in greenhouse (temperature ranging from 20.2 to 32.9°C with average of 24.7°C) in contrast to the 56% outdoors (17.7~24.8°C, 20.6°C in average). However, the growth and development of fruits were more rapid in greehouse.
