种子的发芽率与活力(生长力或健壮度)并不一定相关,室内发芽率与田间出苗率相距甚远的情况时有出现,这已为国内外许多研究者所重视.单凭发芽率高低作为种子质量的指标,会给生产上带来损失. 本试验的目的,是探索贮藏过程(存放4 The seed germination rate and vitality (growth rate or robustness) are not necessarily related, indoor germination rate and field emergence rate far away from time to time there are many researchers at home and abroad have attention .Only by the germination rate As an indicator of seed quality, will bring loss of production.The purpose of this experiment is to explore the storage process (storage 4
