Using epicotyls of kumquat(Fortunella crassifolia Swingle)seedlings growing in vitro as explants,an efficient regeneration system was established.The results show that,using 35-day-old epicotyl segments of kumquat,and based on the culture media of MS+6-BA 2.0 mg/L+NAA 1.0 mg/L+KT 1.0 mg/L+sucrose 3%+agar 0.8%(pH5.7)in the tempreture of 26℃ for a 16/8 h light/dark cycle and without dark-culture,adventitious shoots regenerated from 90%of the epicotyl explants.
