摘要
2009年吉林省气候异常,通化市农业科学研究院通过试验研究了水稻种子含水量与发芽势、发芽率的关系,试验表明:水稻种子含水量与发芽势、发芽率均呈直线正相关,发芽势与含水量呈极显著正相关,而发芽率与含水量正相关不显著。即在室温条件下自然降水将会导致水稻种子发芽势、发芽率降低。
Considering the abnormal climate in Jilin in 2009,the experiment was conducted to study the relationship between seed moisture and seed germination potential and germination rate.The results showed that seed moisture had linear relationship with seed germination potential and seed germination rate,and the seed moisture had very significantly positive correlation with seed germination potential but non-significantly positive correlation with seed germination rate,which indicated that the decrease of seed moisture in room temperature could lead to the decrease of seed germination potential and germination rate.
