Abstract
The aim of the experiment was to detect differences in the activity of the photosynthetic apparatus in 10 genotypes of winter triticale. Measurements of gas exchange and chlorophyll fluorescence were performed. Among the tested genotypes, the photosynthetic apparatus of Timbo and Piano was the most active, while the photosynthesis of both Babor and Boreas was highly reduced. Additionally, we have found significant correlations between the yield and some parameters of chlorophyll fluorescence and leaf gas exchange. Parameters of chlorophyll fluorescence are useful for estimation of the functional state of the photosynthetic apparatus and could become selection criteria in plant breeding. Moreover, such parameters permit definition of the effectiveness of the utilization of chlorophyll a excitation energy and co‐operation of the light phase reactions, with reactions occurring during the dark phase of photosynthesis.
