Abstract:: Taking one aged vitro shoots of Aluns cremastogyne Burkill. Syringa retiulata var. mandshurica,Prunus maackii,Sorbus pohuashanensis (Hance)Hedl.,Phellodendron amurense Rupr as the materials, their cold tolerance under different low temperature by detemining therelative electric conductivity in vitro shoots of trees were studied.The semilethal temeperature of the above shoots were gotten from Logistic equation.The results showed that the relative electric conductivity increased as a S-curves with the decreased of temperature. There were differences among the different spices, there was a sharp increasen Prunnus maackii and increase of REC on Phellodendron amurense Rupr. According to these S-shapedcurves and the Logistic equation, it could be calculated the semi-lethal temperature (LT₅₀.)of Aluns cremastogyne Burkill.,Syringa retiulata var. mandshurica,Prunus maackii.,Sorbus pohuashanensis (Hance)Hedl. and Phellodendron amurense Rupr.whice was -31.53, -29.56, -25.76, -27.85 and -33.12℃ respectively. Among the five species,the cold tolerance of Phellodendron amurense Rupr.stick was the strongest,followed by Aluns cremastogyne Burkill.,Syringa retiulata var. mandshurica,Sorbus pohuashanensis (Hance)Hedl.and Prunus maackii.
