The Relations of Electric Conductivity with Physiological Characteristic of Soybean (Glycine max (L.) Merr) Seeds by Matriconditioning Invigoration Treatment When Stored

Abstract

Invigoration can be applied prestorage treatment, midstorage treatment, and presowing treatment. The research was aimed to determine the relations of electric conductivity with viability on soybean seed after storage. The research was conducted from August 2017 to February 2018. This research was conducted by completed randomized design with factorial 2 factor and 3 replications, i.e time of invigoration and kind of invigoration. The observed variables i.e water content (WC), seed germination (SG), index vigor (IV), electric conductivity (EC). The result showed that WC, IV and EC which is not interactions between treatment, while SG showed that it has interactions between treatment. The regression shows the influence of EC by a factor of seed physiology, which is EC‑WC has a positive correlation, EC‑SG and EC‑IV have a negative correlation. Electric conductivity can be used as one factor in determining the viability of seed that reflects the level of meltdowns of the cell membrane. The seed with high electrolyte meltdowns (W1M4) was considered low vigor, while low electrolyte meltdowns (W3M2) was considered high vigor.
