洋蔥種球大小及低溫處理期間對抽苔、開花、採種量影響之研究

張明聰 余合

摘  要

本省洋蔥採種因冬季低溫不足,種球栽植前須行低溫(5∼10℃)處理二個月,而種球大小以中球(直徑6.6∼8.0cm)以上者為最佳,採種地以本省南部地區較為適合,每10公畝採種量可達27.2∼45.4公斤。


Study on the Effect of Bulb Size and Duration of Low Temperature Treatment on Bolting, Flowering, and Seed Yield of Onion

M. T. Cheng and H. Yu

Summary

        The rests of this experiment showed that in order to obtain better seed production, the onion bulb required two months 5~10℃ low temperature treatment before planting and the optimum bulb size being 6.6~8.0 cm in diameter.  The southern part of Taiwan seems to be the suitable area for onion seed production.  Seed yield obtained in this experiment has reached 60~100 pounds per 0.1 hectare.
