| Abstract:
Investigations on the effect of temperature and light regimes on the course of the germination process, the germination energy and the germination ability of seeds were carried out using five Althaea officinalis L. accessions of various geographic regions /USSR. Czechoslovakia and Japan/. The investigations reveal that all studied accessions placed in Jacobssen's apparatus, at variable temperature /20–30°C/ in the light have best germination ability, highest germination energy and shortest period of germination. Lowest germination energy and germination ability is observed in case the seeds are placed in a thermostat at constant temperature of 20°C in the dark. Seed accessions of Czechoslovakian and Japanes origin possess highest germination energy and germination ability. | |
