Abstract: Seeds of Pinus bungeana from 4 different provenances were studied. Results showed that seed size, 1000-seed-weight as well as the compositions of fat acid and amino acid of seeds varied according to provenances. Seeds from Lin-feng and Ling-chuan appeared to be more dormant and more resistant to osmotic water stress. Under the temperatures of 25/20 and 25/15(day/night), however, seeds of all the 4 provenances germinated quite well, dictating no significant combination effect of provenance and temperature.
