Acacia nilotica (L.) wild ex Del belongs to the family Leguminosae commonly known as Babool or Kikar, is a multipurpose legume tree. Acacia nilotica (gum Arabic tree, babul, Egyptian thorn, Sant tree, Al-sant or prickly acacia; called thorn mimosa in Australia; lekkerruikpeul or scented thorn in South Africa) is a species of Acacia (wattle) native to Africa and the Indian subcontinent. It acts as a biological control agent for herbivores. It is found in the central belt of Indian subcontinent and Australia. This plant has been used as a source of pulpwood, timber, fodder and gum. The whole parts of the plant used for medicinal purposes like barks act as astringent which found to be useful in the treatment of dysentery, diarrhea, leprosy and smallpox. This plant also shows antioxidant activity. The leguminous trees are one of the most significant components of forest vegetation due to their economic and ecological importance. However, the regeneration rate of this plant in natural surroundings is quite low. In general, the woody plants are difficult to regenerate under in vitro conditions but some success was achieved in a few leguminous tree species except Acacia nilotica. In vitro regeneration protocols have been standardized earlier in some other species of Acacia like A. mearnsii De Wild, A. catechu Willd, A. sinuate, A. chundra, A. Senegal except A. nilotica(L.). However, a large number of publications are available regarding its antimicrobial activity, antioxidant activity. This experiment describes a successful protocol on in vitro propagation of A. nilotica from nodal explants of in vitro grown plants. An efficient regeneration protocol was developed for in...
