种子发芽率是指在最适宜条件下,在规定天数内,全部发芽的种子数与供试的种子数的百分比。它是决定种子品质和实用价值的主要依据。但是,直接发芽测定比较慢;尤其是遇到休眠种子,无法得出正确结论。长期以来,许多人在谋求一种快速、简易而准确的测定法,但都不够理想。近年来我们在实践中摸索出溴麝香草酚蓝法(以下简称 BTB 法)效果较好,现介 Seed germination rate is under the most suitable conditions, within the specified number of days, the total number of seeds germinated and the percentage of the number of seeds tested. It is the main basis for determining seed quality and practical value. However, the direct germination assay is slow; especially in the case of dormant seeds, no correct conclusions can be drawn. For a long time, many people are seeking a quick, easy and accurate assay, but neither is ideal. In recent years, we explored in practice bromothymol blue method (hereinafter referred to as BTB method) is better,
