Gas exchange and Triticum sp. with different ploidy in relation to irradiance
Original language description
Different species of Triticum were grown during a greenhouse experiment, including T. monococcum L., T. dicoccum Schrank, T. durum Desf., T. spelta L. and T. aestivum cv. Vánek. The goal was to establish the influence of irradiance on the parameters of photosynthetic performance in relation to their ploidy. Photosynthetic rate - Pn, transpiration - E- and stomatal conductance -gs- were measured.In all monitored species, saturation irradiance for photosynthesis at the level of 609 mikromol was reached. The highest average Pn was measured in the diploid T. monococcum while the lowest Pn occurred in the hexaploid T. spelta. The Pn in hexaploid T. aestivum was comparable with the tetraploid T. durum. Similarly, E also decreased with the increase of ploidy. The highest gs was measured in T. durum and T. aestivum. In all monitored species a close linear dependency was recorded between Pn and gs. Species with lower ploidy reach maximum values of Pn with lower gs. Hexaploid T. aestivum and tetraploid T. duru
