|Title:||In vitro high frequency regeneration of plantlets of Vigna mungo and their ex vitro growth|
Singh, R R
Chaturvedi, H C
|Abstract:||Of the five explants of V. mungo var. T9 used, the excised shoot tips gave best response with regard to offshoot formation followed by the embryonal axis explants. While a treatment comprising 0.5 mgL-1 BAP, 0.5 mgL-12iP and 0.1 mgL-1 NAA induced differentiation of an average 10 offshoots in shoot tip explants, only 3 offshoots were formed in the explants of embryonal axis in a treatment containing 0.5 mgL-1 BAP and 0.1 mgL-1 NAA, found optimum for them. Multiple shoots differentiated when explants with earlier regenerated and growing offshoots were first cultured in a treatment containing 0.1 mgL-1 BAP, 0.25 mgL-1 IAA and 5 mgL-1 CCC and then subcultured in the same treatment but having only 1 mgL-1 CCC. The isolated shoots rooted in 0.5 mgL-1 IAA resulted in the formation of complete plantlets of an average height of 15 cm in 20 days. The in vitro, regenerated plants grew normally under field conditions and came to flowering as well.|
