The paper shows the influence of microwave radiation on the kinetics of germination of white lupine and consumptive pea seeds. Germination curves were obtained using an electronic germination apparatus designed and constructed in the Department of Physics, University of Life Sciences in Lublin. Obtained curves were described with the logistic function which parameters were also determined. Experimental data revealed that 5 sec long exposure to microwave radiation accelerated germination, while 10 sec long exposure resulted in delaying the germination, when compared to the non-exposed control seeds. A hypothesis has been put forward that it may be caused by excessive absorption of radiation leading to harmful warming of seeds.
