| Abstract: | Like other species of the genus Keteleeria (Pinaceae), the seeds of Keteleeria evelyniana and its variety K. evelyniana var. pendula have developed seed wings, and both are rich in oil and prone to loss of vitality. By investigating and analyzing the plant height, number of leaves, length of leaves, and number of branches of seedlings within 2 years of two Keteleeria varieties, this study explores their growth characteristics, providing a basis for many studies, such as population propagation, protection and development. The results showed that the growth of K. evelyniana var. pendula is slightly better than that of K. evelyniana var. evelyniana in the first year of the seedlings, while the growth of K. evelyniana var. evelyniana was significantly better than that of K. evelyniana var. pendula in the second year. The growth of plant height and leaf number of the seedlings of K. evelyniana var. evelyniana and K. evelyniana var. pendula reached their peaks between next June and September, while they were in a slow growth period during the winter and spring dry season from November to next April; There is a positive correlation between the plant height, number of leaves, and leaf length of two Keteleeria varieties. Climate change, especially the level of temperature and precipitation, has a significant impact on the growth of young seedlings of K. evelyniana var. evelyniana and K. evelyniana var. pendula. |
