Considering the imporatance of some aquatic macrophytes in Bangladesh and their gradual declination of the population from the natural habitats, ex- situ culture studies of five selected species, namely, Nymphaea rubra Roxb., Enhydra fluctuans Lour., Ipomoea aquatica Forsk., Hygroryza aristata (Retz.) Nees ex Wight & Arn. and Limnocharis flava (L.) Buch. were carried out. So, ex-situ culture studies for their conservation and at the same time to know the nutritional properties of these aquatic plants have been investigated. Comparing the biochemical composition of the above mentioned five...

Wetlands are the most threatened ecosystems of the world. In a country like Bangladesh which is burdened with overpopulation and a constant increasing demand of food production, the wetlands and its aquatic plants are the most vulnerable items in view of the agricultural land accretion processes. But on the other hand protection of wetland ecosystems with its biodiversity must also be ensured for a safe environment. In the backdrop of this, study related to growth, regeneration and autecology of four selected wetland macrophytes, namely, Euryale ferox Salisb., Nelumbo nucifera Gaertn.,...
