Leaves, roots and seeds of soybean and cotton were subjected to a series of temperature stress of 30, 34, 38, 42, 46 and 50 Centigrade to measure the ion efflux from the cell. Soybean leaves leaked more electrolytes at 313 mu S/cm than cotton leaves which recorded the electrical conductivity of 143 mu S/cm at 50 Centigrade. Below the stress at 42 Centigrade relatively less ions were effluxed as compared to 42 Centigrade or above where severe damage to cell membrane occurred and more than 50% electrolytes leaked from leaves, seeds and roots of both crop plants.
