Heat rate measurements by temperature scanning calorimetry

Heat rate measurements by temperature. scanning calorimetry 

Heat conduction differential scanning calorimetry methods for the measurement of metabolic heat rates of plant tissues as a continuous function of temperature were developed by Hansen and Criddle [19]. Thermally induced transitions and heat rates can be determined simultaneously. 

One important finding from the initial scanning calorimetry studies on plants was that high temperature inactivation as a direct consequence of lipid phase transitions in plant tissues is unlikely. Such transitions, if they exist, can not involve more than 6% of the total lipids. These findings support the conclusions of Rank et al.[38] obtained by temperature cycling methods that inactivation is a function of time and temperature, but it is unknown what physical event or events, or even if there is such an event, that initiates plant stress at temperatures causing chilling or heat shock.
