Abstract: The effect of light and temperature on seed germination of Lilium callosum was studied in the paper. The results showed that temperature in the dark environment had influence to seed germination of Lilium callosum which had been cultivated for 4 years and its optimum temperature to seed germination was 25℃. Germination began 4~5 days and ceased 1~2 weeks after the initiation of the experiment. The percentage of seeds germination was decreased with increase of decrease of temperature. But the exception was 5℃ when the rate of the seed germination had been greatly improved and seed couldn't germinated at 35℃. Seed germination of different fruit in the same infructescence varied with the fruit's location in the infructescence. Seed germination of the lowest fruit is superior to the middle fruits, then the upset. The result also revealed that seed germination was also influenced by the seed location in the fruit, in which seed in the middle was superior to the lowest and then the upset. Seed germination had positive correlation to the weight of a thousand seeds. Under the same experiment environment, seed germination of wild Lilium callosum kept up with that of cultivated Lilium callosum while the germination duration was also longer than cultivated Lilium callosum for about 14 days. At last, seed germination of Lilium callosum which had been stored indoor for 1 year didn't decrease.
