Abstract:

Legumes play an important role in providing the mankind’s food and keeping the food equilibrium in nourishment, belonging to one of the most economic important and biggest families i.e. Leguminosae. This review emphasizes on discussing the diversity and ecoadaptability of the environment on botanical features, nitrogen fixation and biochemical components of Leguminosae, especially legumes in the Papilionoideae. Though these features such as hard seeds, nitrogen fixation and anti-nutritional compounds (ANCs) are disadvantageous in the aspects of agronomy, photosytherate accumulation and the processing and consuming of seed, they may have very important functions in germplasm existence, multiplying and survive to the different circumstances, which had kept the abundant and distribute ecosystem adaptability of these species extensively. It is important and realistic to discover and utilize of tolerance and resistance to the stress circumstances of Leguminosae, and study and inquiry into its adaptability mechanism for keeping biodiversity and tolerance breeding of these plants.

Key words: Leguminosae, biodiversity, nitrogen fixation, anti-nutritional compound (ANC) , ecoadaptability
