Abstract:

Groundnut kernels are highly sensitive to seed deterioration mainly due to their chemical composition and moisture content. During the seed deterioration membrane degradation precedes loss of seed vigour and germination. Membrane degradation is measured by the electrical conductivity of seed leachate. The test is a simple, fast, inexpensive and non-subjective method to assess seed physiological potential and can be used to predict the field emergence. The electrical conductivity of seeds which is an indicative of seed vigour level is normally conducted by soaking 25 number of seeds in 50 ml of water in groundnut. However, all the 25 seeds may not have the same size and weight which may not give concurrent value when replicated. Hence, to get constant value, different methods viz., weight/volume, volume/ volume and number/ volume of seeds and water were followed in the estimation of electrical conductivity in groundnut var. TMV 13. The results revealed that soaking the seeds by weight/volume method at 1:4 (10 g seeds soaked in 40 ml distilled water) soaked at 25oC for 12 hours gave constant electrical conductivity value than the other two methods.
