中文摘要 | 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,其發芽率明顯下降。所以種子以篩選及風選方式,去除發芽較不良部份之 種子,對芹菜種子品質提昇是有幫助的。本試驗同時發現因環境不良造成種子的傷害,以 小粒及千粒重較輕的種子較敏感,且品種間有所差異。 |
英文摘要 | 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 five fractions. The results showed that large seed had highest germination percentage-rate and uniformity among the three seed sizes. Seed germination characteristics could be separated clearly with blower. Lighter seeds had lower germination characteristics than heavier seeds. Cultivars used in this experiment presented a critical mass that germination characteristics decreased apparently. The seeds of white plume- white leaf cultivar was in small size with 4.0 blowing valve. The seeds of green plume-green leaf cultivar was in medium size with 3.5 blowing valve. The seeds of white plumegreen leaf cultivar was in medium size with 4.0 blowing valve. Decanting this lower germination characteristics seed would be helpful to improve celery seed quality. In addition, lighter seeds ",as more sensitive to the environment that causing seed deterioration than heavier seeds. |
