The effects of BA concentrations on floral organ differentiation of leaflet-derived calluses of peanut were studied.The development of floral organ in test tube was observed.The results showed that:calluses generated from peanut leaflets in medium MSB+1 mg/L BA+0.5 mg/L KIN+2 mg/L IAA,were sub cultured in media MSB supplemented with 0,1,2,3,4 and 5 mg/L BA,respectively.Floral organs were differentiated in media MSB supplemented with 1~3 mg/L BA.The induction efficiency of floral organs in medium MSB+2.0 mg/...
