Abstract
By investigating conductivity,dehydrogenase,germination percentage and germination index of cryopreserved Chinese pine seeds,feasibility of long-term storage of the seeds was studied.The results showed that:(1)the freezing and thawing was the main factor affecting the cryopreservation of the seeds;(2)cryoprotectant reduced the damage of the seeds cryopreserved,DMSO's function was comparatively obvious;(3)the cryopreservation can be applied to store the Chinese pine seeds,and the optimal treatment combination was(10%) DMSO + quick freezing + slow thawing.
