Abstract:
Soybean is an important protein rich oilseed crop that is cultivated in the tropical, sub-tropical and temperate regions. It is gaining worldwide importance due to its high nutritional benefits. As soybean seeds are oleaginous, they are easily prone to oxidative damage apart from this exposure of soybean to high temperatures in the tropics makes storage for longer period difficult. Analysing respiration rate at different temperatures is important to study the effect of storage temperatures on extending the viability and quality parameters of the soybean seed. Measurement of Respiration rates was carried out by conducting experiments at three different temperatures, 30 °C, 15 °C and 5 °C. The respiration rates were calculated as the rate of production of CO₂ equivalent to the rate of O₂ consumption of the soybean seeds. The CO₂ production and O₂ consumption is maximum at a higher temperature of 30 °C and minimum at 5 °C. The respiration rate gradually decreases at 5 °C which correlates to a decline in respiration when the temperature is low.
