Bupleurum falcatum was cultivated at high (35°/30°: day/night), middle (25°/20°) and low (15°/ 10°) temperature conditions by using a biotron. Control plants were cultivated in a green house without temperature control. Bolting: The plants cultivated at middle and low temperature showed very high rate of bolting, while control plants showed less bolting. At high temperature conditions only few bolting was observed and many plants withered. Blooming: The plants grown at middle temperature yielded the highest rate of blooming and fructification. Control plants produced less and the plants grown at high or low temperature gave scarcely any blooming or fruit bearing. Root growth: The growth of the root was found to be favoured by various temperature conditions in the following order: low temperature > middle temperature > uncontrolled condition > high temperature. Saikosaponin content: Little difference was observed in the saikosaponin content of the plants cultivated at various temperature conditions.
