S ummary Exposure of whole sorghum plants to cold (5° C) or hot (30° C) nights, or exposure of shoots only to a range of low night temperatures (5—15° C) reduced both the rate and extent of stomatal opening during the succeeding day. Photosynthesis was correspondingly reduced. The reduction in the rate of stomatal opening could be attributed to a development of water deficits in the leaves.
