Abstract Abstract : callus were induced from cephalotaxue fortunei Hook.f, the effect of hormone, sugar concentration, temperature and quantity of inoculation on the inductivity were studied. under the condition of 3% sugar concentration, 0.75% agar concentration, and 25±1℃,the rate of callus inductivity reached to 90%.the callus inoculation of 2.0g accelerate the growth of callus in a flask 100ml.
