摘要：
Structural and functional aspects of photosynthesis in Conocarpus erectus L., a species native to salt marshes of North America and now cultivated throughout the world for its tolerance against a variety of environmental stresses were investigated under high salinity. This species showed better growth at salt level up to 300 mM, whereas extreme salt stress (400 mM NaCl) resulted in a decrease in growth and other physio-anatomical parameters relating photosynthetic activity. Anatomical characters such as leaf and epidermal thickness, proportion of mesophyll tissue, large cortical cells, efficient conducting tissue (phloem and metaxylem area) and stomatal size as well as density contributed towards salinity tolerance and normal photosynthetic activity in C. erectus.
