【摘要】Aims Mangrove forest is desirable for studying variations in wood structure along an ecological gradient be-cause mangroves are subjected to considerable habitat changes apart from salt stress within a small area. To elu-cidate the adaptive capability of wood structures towards fluctuating environmental conditions, variations in wood structures were investigated in 18 individuals of Rhizophora stylosa representing 6 populations along a natural soil physicochemical gradient in the National Nature Reserve of Dongzhai Harbor, Hainan Province.
Methods Soil physicochemical properties were determined at the sites of 18 sampling trees in six R. stylosa populations. The anatomical characteristics of the secondary xylem were studied in details in the 18 trees by means of light microscopy, laser scanning confocal microscopy, scanning electron microscopy and transmission electron microscopy. Variations in the quantitative wood anatomical features in R. stylosa were assessed in details. Relationships between soil physicochemical variables and the quantitative wood anatomical features were ana-lyzed by means of statistical methods.
Important findings Some common specialized wood structures were
