Abstract:This article applies Haworthia truncate to tissue culture and sterile breeding.Finally we estiablish the rapid propagation systems of Haworthia truncate embryogenic callus. They are :(1)Actuating medium: MS;(2)The differentiation medium:MS+6-BA 2 mg·L-1+NAA 0.1 mg·L-1;(3) Proliferation medium: MS +6-BA 1.5mg·L-1+NAA 0.1 mg·L-1; (4)Rejuvenation and rooting culture medium: MS+ NAA 0.1 mg·L-1。All these mediums should add 3% sucrose、0. 7%agar and with the appropriate ph6.0.At the same time,the culture temperature should set to 25℃, illumination time 8 h.d- 1 and illumination intensity is 2000 lx.
Key words: callus culture;rapid propagation;Haworthia truncate
