LIGHT AND TEMPERATURE PARAMETERS TO OPTIMIZE PHOTOSYNTHESIS IN TWO AMARANTHUS L. SPECIES

Among the numerous taxonomic group of Amaranthus L., 12 species are cultivated as vegetable, cereal and fodder crops, medicinal and ornamental plants. A limitation for their introduction in Russia results particularly from lack of data on the physiological and ecological parameters of plant growth and development, which prevents the effective breeding investigations, especially with a view to create varieties for cultivation in northern regions, where the temperatures during spring vegetation are low. In controlled conditions of two factorial preplanned experiment we studied the effect of light intensity and temperature to net photosynthesis in intact Amaranthus cruenthus L. plants (Sultan variety) and A. hypochondriacus L. plants (Krepysh variety).
