《农作物种子检验规程》系列标准《农作物种子检验规程》系列标准Rules for Agricultural Seed Testing陇闪Z‘‘人切JZ比拍921 Jianyan Guieheng xilie bicozhun《农作物种子检验规程》系列标准(双以公for心成以‘盯以%26记Test吨)确定种子品种和种用价值，促进农业生产的一种检验手段。种子是一种有生命的生物产品，其品质检验不同于非生物产品那样能准确地加以鉴定。因而在进行种子贸易、交换和使用中，对同一批种子采用的检验方法应具有较高的准确性和再现性。为此目的，特别是为让农民使用品质好的种子，颁布了国家标准《农作物种子检验规程》(CBIT 3543一1卯5)。该标准不仅规范了种子田间检验和室内检验方法中的传统作法，而且还参照美国、加章大和澳大利亚等国家标准，在种子的净度检验、纯度检验、发芽实验和种子生活力测定等方面采用了一些国际上的先进科学方法。例如，在种子生活力的测定中，采用了“靛红染色法”，其原理是根据有生命力的种子的胚细胞原生质，有选择渗透的能力，使苯胺染料不能进人活细胞内部，因此不染色，而死细胞原生质则无此能力，故被染成蓝色，由此可鉴定有生活力和无生活力的种子。再如，在品种纯度检验中使用石炭酸染色法等均是运用现代科学技术，使农作物种子检验规范化，从而确保农作物种子的品质，为中国农业产品的优质高产提供了先决条件。(陈志田)
