不同活力红松种子的田间表现

对发芽能力分别为87％和92％的红松种子，进行了田间对比试验和生理测定。结果表明，高活力种子具有较高的发芽率、出苗率和保苗率，其出苗过程迅速而整齐，光合作用功能叶的叶录素含量较高，根系活力强，苗木生长健壮，具有较强的适应能力。

The Field Expression of Pinus Koraiensis Seeds With Different Vigor

Field experiment and physiological measurement were done for Korean Pine seeds which have 87% and 92% seed vigor respectively. The results show that the seeds of high vigor are better in germination percentage, rate of seedling emergence and rate of seedling preservation. They are also quick and simultaneous in process of seedling emergence. The seedlings which were from seeds of high vigor have high chlorophyl contents of photosynthetic function leaves, vigorous root system, strong seedling, better adaptability.
