- Observation Mortality of Magnolia stellata seedlings in the growing season of the first year was 3.4%, much lower than in previous studies.
- Observation Mortality of Magnolia stellata seedlings in the winter season of the first year was 7.7%.
- Observation In the winter of the first year, 10 of 13 seedlings were killed by uprooting due to frost heave in wet locations.
- Observation Seedlings that grew in wet sites and germinated early showed good height growth in the first year.
- Association In the second year, soil moisture and germination timing had no effect on relative growth rate.
- Association Initial height was correlated with height growth in Magnolia stellata seedlings.
- Association Soil moisture conditions had positive effects on seedling growth and survival in the growing season of the first year.
- Association Soil moisture conditions had negative effects on seedling growth and survival in the winter season of the first year.
- Association Soil moisture conditions had no effect on seedling growth and survival in the second year.
