Sažetak
Cercis siliquastrum L.(Caesalpiniaceae), the Juda's tree is a native shrub or tree of the coast and islands of the Mediterranean area of Yugoslavia. The investigation of transpiration (Tr) of leaves was carried out using STOCKER'S method in natural conditions. Stomata opening degree was determined by infiltration method. Microclimatic factor investigations were also performed. The roundish, deeply cordiate, glabrous leaves of C. s. are dorsiventral, amphistomatic and are on the average 184 μ thick. Stomata density of upper epidermis was 23, 7 /mm^2 and lower epidermis 273, 0 /mm^2. Stomata dimensions (in μ) on the upper surface (27, 36 x 17, 18) and lower surface (27, 30 x 16, 98) are rather similar. The biggest among the measured Tr values was 28, 34 mg/g/min on 16.07 at 4h p.m. and the minimal Tr value 5, 26 mg/g/min on 1.08. at 10h a.m. The average quantity of transpired water in a min. was 13, 99 mg per gramme on a leaf. In July and September the Tr value was considerably higher in comparison with the values measured in August. Positive correlation between Tr, microclimatic factors and openings of stomata was found.
