Global change such as altered precipitation patterns and increased atmospheric nitrogen (N) deposition will have significant impacts on seedling growth during plant recruitment. However, how interactive effects of increased precipitation and N deposition on forest seedling performance have not been well investigated. In this study, we conducted a two-year field experiment that manipulating precipitation amount (ambient rainfall and 25% increment during the wet season) and exogenous N addition (0 and 100 kg ha−1 yr−1) in a tropical secondary forest. Seedling growth, morphology and nutritional status of a dominant tree species (Cinnamomum burmanni) were measured. Results showed that increased precipitation had …

Establishing seedlings in subtropical plantations is very important for forest health, succession and management. Information on seedling nutrient concentrations is essential for both the selection of suitable indigenous tree species to accelerate succession of the established plantation and sustainable forest management. In this study, we investigated the concentrations of nitrogen ([N]), phosphorus ([P]), and N∶P ratio in leaves, stems and roots of seedlings of three indigenous tree species (Castanopsis chinensis, Michelia chapensis and Psychotria rubra) transplanted with removing or retaining understory vegetation and litter at two typical subtropical forest plantations (Eucalyptus plantation and native species plantation). We also measured the …
