种子纯度是种子质量分级最重要的依据,如何准确鉴定种子纯度是确定种子质量等级的关键。GB/T3543～1995《农作物种子检验规程》和ISTA(国际种子检验协会)1996《国际种子检验规程》都将田间小区种植鉴定作为种子纯度鉴定最可靠最准确的方法,但两个《规程》中关于田间种植鉴定的各个步骤、各个环节的要求并不具体,可操作性不强,不同地方不同检验人员执行起来差异较大,而且,不同作物的播种方式、最佳鉴定时间等关键环节存在较大的不同。本文中笔者根据多年从事种子质检工作的体会,总结出一套较为完整的杂交玉米种子纯度鉴定技术,供同行们参考。
Seed purity is the most important basis for seed quality grading, and how to accurately identify seed purity is the key to determining seed quality grade. GB / T3543 ~ 1995 “Crop Seeds Inspection Regulations” and ISTA (International Association of Seed Testing) 1996 “International Seed Inspection Regulations” are the most reliable and accurate method for identification of seed purity, but the two “rules” There is no specific requirement in every aspect of field planting identification, and the operability is not strong. Different inspectors in different places have great differences in implementation. In addition, there are many key links such as sowing methods and best appraisal time for different crops Big difference. In this paper, based on many years of experience in the work of seed quality inspection, summed up a more complete set of hybrid maize seed purity identification technology for your colleagues for reference.
