改进评价种子质量方法的呼声由来已久。实验室中用萌芽种子所占的比例(萌芽百分率)能准确地测定出种子的质量。如果现场条件有利,可以预测苗圃出苗情况;若是出现对苗床不利的条件时,就不能确切地预测出苗的比例。曾有人提出评价种子“活力”的单一方法,即一般被认为“在大田条件下,决定种苗迅速而同期出土及正常生长发展潜力的特性”。
The voice of improving the method of evaluating the quality of seeds has been around for a long time. The proportion of germinated seeds in the laboratory (percentage of germination) can accurately determine the quality of the seeds. If the site conditions are favorable, nursery emergence can be predicted; if there is adverse conditions on the seedbed, you can not accurately predict the proportion of emergence. A single method for evaluating seed “vitality” has been proposed, which is generally considered to be “the property that determines the potential for prompt and simultaneous excavated and normal growth of seedlings under field conditions.”
