Abstract:

Abstract: The influences were studied of variety, basic medium, hormone combination and slice block of callus on the callus differentiation culture of Anthurium andraeanum. The results have suggested that, in the same cases, bud induction rate, growth velocity and growth status of different varieties of callus of Anthurium andraeanum has larger difference. The suitable medium for bud induction was 1/2MS basic medium，and Differentiation seedlings grew more haleness and taller, and their leaves are green. The optimum hormone combination was BA 2.0 mg／L+NAA 0.1 mg／L with the largest number of adventitious bud differentiation ，and each callus produced 14.8 adventitious buds on the average. When the slice block of callus was 10×8×5mm3, callus enlarged more times, adventitious bud differentiated much more and growth vigor of differentiation seedlings was much better.
