1种子活力及其测定方法研究进展1.1种子活力种子活力是衡量种子质量的重要指标。优质种子的一个基本特征是具有较高的活力。在相当长的时期内,评价种子的质量都以最适宜的标准发芽条件下所测得的发芽率来表示,并且把种子萌发结果归结为发芽和不发芽的两点分布。在我国,目前则普遍采用郑光华总结的
1 seed vigor and its determination of the progress of research 1.1 Seed vigor Seed vigor is an important indicator of seed quality. A basic feature of high-quality seeds is their high vigor. For a fairly long period of time, the quality of the seeds evaluated was indicated by the germination rate measured under the most appropriate standard germination conditions and the seed germination results were attributed to a two-point distribution of germination and non-emergence.
