Study on Celery Seed Quality with Seed Grading Technics

Abstract

青骨、白骨芹菜兩品種種子以風選刻度5以上分級處理顯著提高發芽率8.5﹪以上。經篩選處理之中粒種子可明顯增加發芽整齊度及縮短平均發芽天數。種子比重在1.00至1.15之間之種子有最高發芽率，分別為98﹪與86﹪，而比重介於1.05至1.10之種子發芽整齊度天數及平均發芽天數均被縮短。胚生長速度以中粒種子及風選後比重小於1.05之種子較快。The germination percentage of two varieties celery seeds from Spick Company were significantly increased 8.5% as seeds blew above scale 5 of seed blower. The medium size of seeds significantly decreased the GT90-10 and the mean germination days. The seed density being 1.00~1.15 could increase the seed germination percent. The seeds that have 1.05~1.10 seed density improved the uniformity of germination and the mean germination days. The growth rate of embryos of the medium seeds or seeds having the density lower 1.05 were faster than those of other treated seeds
