芹菜種子篩選分級之研究

Abstract

芹菜種子發芽緩慢不規則,且種子成熟不一又細小,故一批種子常參雜著大小 不一及重量不相等之種子。本試驗借由種子大小篩選及種子重量風選等方式做種子分級, 以比較各級種子活力之差異,供育苗及種子生產之參考。試驗結果顯示,種子大小以中粒 種子所佔比率最高,而大粒種子有較優之發芽率、發芽速度、發芽整齊度及幼苗鮮重,中 粒種子表現次之,小粒種子表現最差。大、中、小粒種子分別經過風選後發現,白骨白葉 小粒種子4.0風力級數以下、青骨青葉中粒種子3.5風力級數以下、白骨青葉中粒種子4.0 風力級數以下,其發芽率Celery seed germination is slow and irregular. Celery seed size is very small, and seed mass is different. The objects of this experiment is to study the quality of celery seeds by sorting their size to three fractions, and blowing their mass to
