Popis: Within the frame of an extended field experiment the CO2 and H2O gas exchange between a triticale field and the atmosphere was measured during the period between heading and harvest in the summer of 1995. Diurnal courses of H2O loss, CO2 gain and leaf conductance were obtained together with microclimatic parameters for leaves of different insertion levels. Patterns of dependence of leaf gas exchange on microclimatic conditions were determined. Based on the results of porometric measurements and crop structural parameters (LAI) gas exchange was scaled up to canopy level.
