用电导率测定种子活力,早在1928年Hihbard 就开始,其后Perrg(1967)提出电导率的测定能为种子活力提供一个满意的指标,T.M.Ching(1973)提出种子快速定糖法,就是利用种子内可溶性糖通过不完整细胞膜外浸,从而提高了浸泡液离子浓度的着色反应来鉴定种子活力。近几年来,国际上利用种子电 Determination of seed viability using conductivity started as early as 1928 when Hihbard started. Perrg (1967) later proposed that the determination of conductivity provides a satisfactory indicator of seed viability. TMChing (1973) proposed a rapid seed setting method using seeds Soluble sugars in the seeds through incomplete membrane extrapolation, thereby increasing the color of the soaking solution ion concentration to identify seed vigor. In recent years, the international use of seed electricity
