Abstract

The new plant growth conditions available in the reconstructed Martonvásár phytotron, which differ considerably as regards the spectral composition of the light, made it necessary to investigate whether previously elaborated phytotronic methods (e.g. for the testing of frost resistance) could be used unchanged under the present conditions or whether modifications were required. The expreiments were designed to trace the frost resistance of winter cereals grown at identical photon flux density provided by fluorescent tubes or metal halide lamps. The experiments also made it possible to compare the dynamics of seedling development in plants raised in light with different spectra. Winter wheat, rye, triticale, durum wheat, barley and oat varieties were used in the experiments. No significant difference was found between the frost hardiness of plants grown under light sources with different spectra but identical photon flux densities for any of the species or varieties. However, the leaf area and above-ground green mass of four of the winter wheat varieties tested were significantly higher in the sixth week of growth for plants raised under metal halide lamps; this difference was not significant for the other four varieties. It can be concluded from the results that photon flux density plays a decisive role in the hardening processes of winter cereals, while certain phenological traits are influenced by the spectral energy distribution of the light source.
