Loss in Germinability of Heat-treated Wheat Seeds is Associated with Reductions in Electrical Conductance of Their Leachates

Mohammad Ashraf, Faiz-ul-Hassan Nasim and Mohammad Munir Hussain

Abstract:
Wheat seeds of two high vigour cultivars, Inqalab and Pasban, were heat-treated at 55±2 °C and 70±2 °C in presence (wet) or absence (dry) of water for 1 day. Germination tests exhibited reductions in percentage seed germination with increase in the pre-treated temperature and zero percent germination was exhibited in 55±2 °C (wet) treated seeds. `Pasban` seeds were more sensitive to heat-treatment than `Inqalab` seeds. Electrolytes leakage (μS/cm/seed) and rates of electrolytes leakage (μS/cm/seed/h) measured in the first 6 hours of imbibition reduced with increase in temperature treatment compared with that of controls. The correlation between loss in germinability and electrical conductance is discussed.
