三叶芹种子颜色和大小对种子质量和幼苗生长的影响

摘要

研究了三叶芹种子颜色和大小对种子发芽、种子活力以及幼苗生长的影响,结果表明:深色种子的发芽率、种子活力以及幼苗生长量显著高于浅色种子；大粒种子的种子活力和幼苗生长量显著高于小粒种子,大粒种子的发芽率与小粒种子的差异不显著.%The effects of seed color and size on the seed germination, seed vitality and seedling growth of Cryptotaenia japonica Hassk. L. Were studied. The results showed that the germination rate, seed vitality and seedling growth of dark seeds were significantly better than those of light - color seeds. The seed vitality and seedling growth of big seeds were obviously better than those of small seeds, but there was no significant difference in the germination rate between big seeds and small seeds.
