Abstract
The effect of temperature, light condition and scarification on seed germination in Lathyrus latifolius L. was studied using 'Pink Pearl'. Optimum temperature range for seed germination of 'Pink Pearl' was 15 to 20℃ under dark condition. Germination percentage at 20℃ under light condition was slightly lower than under dark condition. Soaking seeds in concentrated sulfuric acid for 16 minutes increased the final germination percentage to 100% at 20℃ as compared to about 30-50% for the water-soaked control. The acid scarification followed by priming with polyethylene glycol 6000 solution (-1.3Mpa) for 1 week at 10℃ increased the germination percentage to more than 85% within 8 days after sowing even at 30℃.
