Ecological Wood Anatomy of Avicennia marina

doi:10.7677/ynzwyj201514166

Abstract

Abstract:

The soil physicochemical indexes including edaphic pH values, edaphic salinity and soil nutrient indexes were determined in 8 Avicennia marina populations located in national nature reserve of Shenzhen of Guangzhou Province. The morphological characters in secondary xylem of Amarina populations corresponding to soil sampling which represented different habitats were surveyed by means of light microscopy and electronic microscopy. Some common specialized wood structures in Amarina growing in different habitais can be observed which suggest they function as safely conducting water under high negative pressure and are thus adaptive to intertidal habitats．These characteristics include the occurrence of: (1) some fibriform vessel elements; (2) vessel vestures and helical structures on vessel walls; (3) parenchyma cells contain lots of starch grains;(4) included phloem. Soil organic matter and soil total salt have significant effect on quantitative wood anatomical features by the stepwise regression analysis.With the increase of soil salinity and soil organic matter content which suggest occurrence of more and more serious “physiological drought”, Amarina is characterized by a higher porosity.and double thickness of vessel wall making contact with an adjacent vessel. The trends inferred that variations in the quantitative wood anatomical features of Amarina growing at different sites are adaptive to heterogenous habitats in the intertidal areas.
