| Abstract: |
| Taking the Tapiseia siriensis introduced from the Wufeng county Yichang city as materials，we
surveyed the seedling height，ground diameter and leaf growth in different months at the Longyuan nursery of Yanling
county，analyzed their growth rhythm，and then fit the growth process of seedlings by using Logistic curve and S
curve. The result showed that the height and ground diameter showed“ S” curves in the whole process of seedling
growth. The fast growth period of plant height started from June to July，accounting for 25.2% of the total annual
growth，whereas the fast growth period of plant ground diameter started from August to September，accounting for
27.2% of the total annual growth. Compared to the S curve，Logistic curve was better suited for describing the growth
of height and ground diameter. The seedling growth could be well predicted by the fitting curves，thus providing
reference for seedling nursery and landscape application． |
