Calli derived from the hypocotyl of avocado (Persea americana Mill cv.‘Hass')were stored at 8℃invitro. The results indicated that the calli when cultured on MS medium + 1. 0mg·1￣(-1)2,4一D+ 3%coconutmilk + 3%sucrose and stored for 6 months still showed comparatively higher viability.The duration ofpreservation might be extended to 8 months by adding 0.40 mg·1￣(-1)paclobutrazol.
