低温胁迫对两种樟树抗寒性生理的影响
The Effect of Cold Stress on the Cold Resistance Physiology of Two Camphor Species
摘要
Abstract
Taking leaves of Cinnamonum bodinieri Levl and C. camphora L. (linalool-type) treated by cold temperature as test materials, the changes of MDA, Proline, Soluble protein and SOD activity, electrical conductivity in them were studied. The results indicated that for all the materials, with the decrease of temperature, the ion leakage percentage of the two species increased in S-shape, the SOD and POD activities decreased after an initial increase. The content of soluble protein, MDA and soluble sugar began to drop, then to increase and at last to drop again. By using fuzzy mathematics method, the cold resistance of two camphor tree species was evaluated as Cinnamonum bodinieri Levl>C. camphora L. (linalool-type), the semi-lethal temperature (LT50) of two camphor tree species calculated by the Logistic equation of ion leakage percentage was-12.43,-10.71℃, respectively. At last, by using a fuzzy mathematics method, the cold resistance of C. bodinieri Levl was divided into three periods, namely, the reducing stage, the enhancement setting stage, and the reducing stage.关键词
