种子活力(vigor)也称种子精力,是表示种子质量的重要的指标之一。包含着迅速整齐的发芽潜力(尤其是在逆境条件下)以及生长和生产潜力。在实践中,我们常遇到如实验室里的发芽率一样,而田间播种后出苗、生长和苗木产量、质量却有很大差异的现象。这说明种子的活力状况不同。通常活力高的种子出苗、生长、苗木产量都优于活力低的种子。可见,对树木种子的活力状况
Seed vigor, also called seed energy, is one of the most important indicators of seed quality. Contains rapid and orderly germination potential (especially under adverse conditions) as well as growth and production potential. In practice, we often encounter the same as germination rate in the laboratory, and the emergence of seedlings after planting, growth and seedling yield, quality is very different phenomenon. This shows that the vitality of the seeds is different. Usually high seed vigor, emergence, growth, seedling yield are better than low-vigor seed. Can be seen on the vitality of tree seeds
