This study examines the physiological properties of pepper and potato leaves, including leaf thickness and number of stomata per 1 square mm. Soil temperature at depths of 10 and 20 cm, air temperature and mean values of transpiration (Tr) for the period 5 July 2008 - 15 September 2008 were also monitored. The obtained results suggest the following: Leaf thickness was far greater in potato (171.82 microm) than in pepper (140.00 microm). The number of stomata per 1 square mm was also considerably greater in potato (241.6) than in pepper (184.1). The highest mean daily transpiration rates of 10.92 mg/g per min in pepper and 11.23 mg/g per min in potato were recorded on 3 August 2008 and 23 August 2008, respectively, indicating a high intensity of transpiration.
