6种槭树属植物种子特性及其发芽试验

Research on Seed Properties and Germination Test of Six Species of Acer

观察了6种槭树属植物种子的基本特性，同时进行了种子发芽试验，结果表明，6种槭树属植物种子形状多数近于球形或卵圆形，不同种子大小差异较大，毛果槭种子千粒重达321．80g，其余种子的千粒重集中于30-50g。6种槭树属植物种子均具有休眠的特性，采用低温湿沙贮藏可以解除其休眠，促进萌发，其发芽率可达70％以上。

Observation on seed properties of six species of Acer and test on their germination showed that thousand kernel weight of most of them was 30 - 50 g, but that ofAcer nikoense reached 321.80 g. The majority of these seeds had similar shape but different size. All of them had property of dormancy that could be relieved after stored at low temperature and wet sand and even could promote the germination, and the rate reached over 70%.
