反映种子活力的生化指标反映种子活力最直观的指标是发芽势和发芽率。此外,四唑(TTC)染色法作为种子活力指标,已得到世界公认。其他如酶活性,呼吸代谢、蛋白质、淀粉等的合成,膜的透性,贮藏物质的降解等,也可作为种子活力指标,但有一定的局限性。(一)四唑法:四唑即2、3、5—氯化三苯基四矬,因为它有几百个衍生物,通称四唑盐,呈白色或黄 Biochemical indicators reflect the vitality of seeds The most intuitive indicator of seed vigor is germination potential and germination rate. In addition, tetrazolium (TTC) staining as a seed vigor index, has been recognized worldwide. Others such as enzyme activity, respiratory metabolism, protein, starch synthesis, membrane permeability, storage material degradation, but also can be used as an indicator of seed vigor, but has some limitations. (A) tetrazole method: tetrazole 2,3,5-triphenyl tetrachloride chloride, because it has hundreds of derivatives, commonly known as tetrazolium salt, was white or yellow
