Özet
The effects of temperature, light and storage on the germination of Ulmus glabra and Ulmus laevis seeds were studied. Germination tests were carried out under constant temperatures of 20°C and alternating temperatures of 30/20°C. Temperature significantly affected seed germination of U. glabra not stored, and seed germination was the highest at 30/20°C under dark or light. Temperature and light (0 or 8 h) did not significantly affect germination of U. laevis seeds not stored. When seeds were stored for 2 years, seed germination of U. glabra and U. laevis was significantly affected by temperature and light (0, 8, 16 and 24 h). Two years storage of U. glabra seeds increased light demands for germination percentage, and the seeds could be stored at 4°C for 2 years without losing its viabilities when germinated at 30/20°C under light. Although germination percentage and germination rate of U. laevis seeds reduced after 2 years of storage, germination parameters were still quite high when seeds were germinated at 30/20°C under light. © 2006 Asian Network for Scientific Information.
