Plants that evolved in warm environments suffer injury when exposed to temperatures below 10 to 15 [degrees] C (Saltveit and Morris, 1990). This phenomenon is initially reversible, but ultimately irreversible and can result in cell death. It applies to many economically important agronomic and horticultural crops and severely limits the geographical areas and seasons in which these sensitive crops can be grown (Saltveit and Morris, 1990). The increasing demand for food because of the growth of the world population has resulted in an increasing use of chilling-sensitive crops in areas of higher latitudes and altitudes (Van Hasselt, 1990). Photosynthesis is one of the first ...
