Plant-biodiversity at Ajmiriganj Haor Homesteads of Bangladesh 14+

📙 Biodiversity is the contraction of biological diversity. Plant-biodiversity is the most important component of total biodiversity. ''Biodiversity" is the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part. It includes diversity within species, between species and of ecosystem. Plant-biodiversity is the plant genetic wealth of a country. Economically and genetically important materials selected by both human and nature, adapted in the environment are the components of homesteads. Homesteads are the in situ conservation sites of wide range of plant-biodiversity. Environmental variations offer unique opportunity to select appropriate genotypes at different regions. Diversity of genes within plant species increases its ability to adapt in adverse environment. Any decrease in genetic variability may lead to ecosystem instability. Plant biodiversity is instrumental to cycling and recycling of nutrients and thereby achieving the stability of the ecosystem.
