摘要

胡蘿蔔早生品種（以色列種）在臺灣平地雖不經低溫處理，也可花芽分化，抽苔結籽良好。晚生品種（日本黑田五寸，美國五寸，加工小胡蘿蔔）在臺灣平地，如不經低溫處理，無法在春季早期開花，但在夏季長日照（日照14小時以上）下，雖不經低溫處理，也可陸續抽苔，但採收種子進入高溫無望。低溫處理，以5℃ 15天或10℃ 30天最安全有效，雖可促進早期抽苔，但採收種子必須延長至5月下旬。

並列摘要

Isral early carrot can produce seeds well in Taiwan, whereas late variety carrots; such as Japan Black-Field 5in, Chantenay and pariser Market, can not flower in spring without low temperature treatment, or flower in summer under long daylight and high temperature conditions, but it is lack of seeds prodcution. Late variety carrots flower well in the range of 5-15℃ treatments and best in 5℃, 15 days and 10℃ 30 days, but seed ripening was prolonged till the end of May, in which seed production was seriously limited by the constant rainfall.
