电导试验作为一种活力测定法,其基本原理是:低活力的种子一般具有较差的膜结构,因而细胞易渗漏,引起种子内的电解质如糖、氨基酸和有机酸较多地渗出,使浸泡液的电导率增加。许多种子的电导率与活力有很好的相关性。AOSA(美国官方种子分析者协会)1977年活力“仲裁”试验指出,电导测定可以鉴别各批大豆种子的活力水 Conductance test as a dynamic assay, the basic principle is: low-powered seeds generally have a poor membrane structure, so cells are easy to leak, causing the electrolyte within the seeds such as sugar, amino acids and organic acids more exudate, Increases the conductivity of the soaking solution. Many seeds have good correlations with their electrical activity. AOSA (National Association of Official Seed Analysts) activity in 1977 “Arbitration” test pointed out that the conductivity measurement can identify the batches of soybean seeds of active water
