8月22日下午1：00—3：00，主题为“Cryomedicine and Cryobiology ”在北京国际会议中心306会议室召开。
演讲内容摘要：
Shoot apices isolated from in vitro cultured Hypericum perforatum L. plants were subjected to cryopreservation using the slow freezing method. The plants regenerated from explants that survived cryopreservation procedure restored their developmental competence,genetic stability at both,cytogenetic (chromosome number,mitotic activity) and a DNA (VNTR sequences) levels and ability to synthesise bio-active substances hypericins. The viability of cryopreserved shoot tips was genotype-dependent and in average did not exceed 20 percent. Amongst the variables that contribute to the survival rate,manipulation with the cooling rates of the cryoprotective solution between the temperatures prior to phase transition and – 40 °C was performed. Experimental data were compared with computer simulation.
