目前,种子测定技术方法繁多,发展也很快。根据种子测定的目的,可归纳为四大类,即种子生活力、种子健康、种子净度、种子品种和遗传纯度的测定。下面就目前应用较多的测定方法,从所需时间、准确度和应用价值等几方面作简要介绍。一,种子生活力的测定方法 1.常规发芽法常规发芽法是评价种子在最适生长条件下萌发的潜力,是测定种子生活力的常规方法。一般用发芽率来表示。发芽天数至少需5天,发芽天数因不
At present, there are many methods for seed determination and its development is fast. According to the purpose of seed determination, can be grouped into four categories, namely, seed viability, seed health, seed purity, seed variety and genetic purity determination. Below the current application of more determination methods, from the required time, accuracy and application of several aspects such as a brief introduction. First, the determination of seed viability 1. Conventional germination method Conventional germination method is to evaluate the potential of seed germination under optimal growth conditions, is to determine the conventional method of seed viability. Generally use germination rate to express. Sprouting days at least 5 days, germination days because not
