iates ( describe temperature as the single most important factor that inuences the quality of horticultural products. Produce storage and shelf life is afunction of both temperature and time (Thompson et al., . The pulp temperature ofthe produce inuences its metabolism and consequently determines the deterioration rate. Ambient temperature favors the growth and development of rot organisms (Thompson et al., . Generally, produce becomes more perishable as its pulp temperature increases.It is therefore essential to lower the temperature of produce after harvest and maintainthis low temperature during transport and handling. Nevertheless, overcooling the producemay cause some adverse effects. Freezing and chilling injuries can result from indiscrimi-nate use of refrigeration. In general, non-chilling-sensitive produce should be held slightly above its freezing temperature, whereas chilling-sensitive produce should be kept slightly above its threshold temperature for chilling injury (Wills et al., . The effect of temperature on fruits and vegetables is also cumulative. Produce qual- ity is eventually affected even if produce is exposed to high temperatures for short, inter-mittent periods (Thompson et al., . Consequently, it is essential to maintain fruitsand vegetables at lower temperatures even for relatively short periods of transport andhandling. Problems of poor temperature management are magnied in cases of long- distance and export shipments, in which produce may be subjected to constantly changing or adverse climatic conditions. For example, in Canada, horticultural produce is importedfrom the southern parts of the United States during winter. Transport trailers have to moveperishable produce from climatic zone where ambient temperatures are generally above3C to zone where ambient temperatures can reach as low as /H1C. In such circum- stances, it is extremely important to consider the wide variation in ambient temperature. It becomes challenge to ma
