Germination of amaranth seeds cv. Aztek and Rawa at various temperatures

Abstract: Amaranth is one of the oldest crop plants in the world, originating from South America and more and more frequently referred to as the cereal of the 21st Century. The period of amaranth vegetation is 160 days. The optimum temperature during vegetation is 26–28°C, and it grows and develops the best within the temperature range of 16°C to 35°C. In the laboratory experiment the germination capacity of seeds was determined. Amaranth seeds were sown on Petri dishes, at 100 seeds per dish in a climate – controlled chamber at temperatures of 10°C, 12°C, 15°C, 20°C, 25°C, 35°C, 45°C, 55°C, in total darkness. Parameters of seeds germination of amaranth cv. Aztek was obtained by modeling of logistic curve: NT = NK [1+exp(β– Kt)]-1. Germination of amaranth seeds of both cultivars, for all the kinds of stimulation and for the control samples, was the highest at temperatures of ca. 20°C and ca. 42°C, and the lowest at 10°C.
