前言长期以来,对种子播种的质量,多用发芽试验法进行检验,即根据发芽率的高低来判断种子质量的好坏。可是,在生产实践中,人们经常遇到实验室的发芽率与田间的出苗率不相符合,有时差距很大。鉴于发芽试验不能完全准确地说明种子播种品质的好坏,人们又在寻求着更为实用的、能准确测定种子质量的方法和依据。这就是六十年代以来,种子学领域里出现的新课题——种子活力。种子活力(Vigor)并非种子生活力(Viablty)。1977年国际种子检验协会(ISTA)代表大会通过的种子活力的意义
Foreword For a long time, the quality of seed sowing, multi-purpose germination test method to test, that is, according to the level of germination rate to determine the quality of the seed. However, in the practice of production, people often encounter laboratory germination rate and field emergence rate does not match, sometimes a great gap. In view of the germination test can not fully explain the quality of the seed sowing quality, people are seeking a more practical and accurate method for determining the seed quality and basis. This is the new issue that emerged in the field of seed science since the 1960s - seed vitality. Vigor is not Viablty. The significance of the seed vigor adopted at the 1977 ISTA Congress
