Abstract:
The origin of Cupressus gigantea is in Linzhi, Xizang.It is a precious timber species and courtyard greening species,belonging to the first class national protecting species. C. gigantea has been introduced and domesticated to Fujian province since 1999.Its seed germination was tested by the method of temperature gradients.The results indicated that its seed germination rate was above 50 percent at 10℃, 18℃, and 25℃, and 41.30 percent at 30℃. Its seed germination rate at low temperature was higher than that at high temperature. The suitable temperature was from 10℃ to 18℃. There was significant difference in seedling growth between C. gigantea and Fokienia hodginsii at one-year-old and two-year-old. The average height of Cupressus gigantea seedlings at two-year-old was 61.8 cm, and the average basal diameter was 0.51 cm. Its root system was developed. It had stable growth potential, and no pest and disease occurrence. The results proved that C. gigantea had a fairly high adaptability in the east of Fujian Province, and it could be introduced and domesticated successfully in Fujian Province.
