一、引言种子质量检验方法的不同,对获得检验结果的正确与否有重大关系。其中,尤以测定种子发芽力和种子水分,是变动较大的检验项目之一,也是检验方法研究中的重要课题。评价种子的发芽能力有不同的表示方法,一般采用种子在恒温下或变温下作发芽试验,于规定时间内计算发芽粒数。我国农业部颁布的试行标准和一些省、市、自治区企业标准规定,计算小麦发芽势和发芽率的天数相应为发芽后的第三天和第七天,而国际种子检验协会通过的1976年种子检验规程中规定为第四天和第八天。为了探究三天和四
I. INTRODUCTION The different methods of seed quality testing have a significant relationship with the correctness of test results. Among them, the determination of seed germination and seed moisture, in particular, is one of the more widely-varying test items and an important issue in the study of test methods. Evaluation of seed germination ability to have different ways of expression, the general use of seeds at temperature or temperature for germination test, calculate the number of sprouted within the specified time. China’s Ministry of Agriculture promulgated the pilot standards and some provinces, municipalities and autonomous regions, enterprise standards, calculate the number of days of germination potential and germination rate corresponding to the germination of the third day and the seventh day, and the International Seed Testing Association passed the 1976 seed Inspection procedures specified for the fourth day and eighth day. In order to explore three days and four
