Adaptation to Immersion of Typha Australis (Schum and Thonn.) From The Study of Anatomical Characters of Leaves

Typha plants, such as Typha australis, are generally found in wetlands. The aim of this work is to understand how the anatomical structures of the leaves explain its strong development potential in wetlands. The results show that the anatomical structure doesn’t differ from that of the macrophytes: the large presence of the aerenchyms and of the air spaces facilitate the transfer of the respiratory gases from the aerial part to the roots allowing an adaptation to the immersion. Moreover, the existence of a palissadic parenchyma on both sides of the leaves as well as a network of lacunar spaces in Typha would optimize photosynthesis.These anatomical characters would favor the adaptation of the species in the wetlands.
