Abstract: In order to explore the resistibility of evergreen Amur honeysuckle, normal Amur honeysuckle and red-leave Amur honeysuckle, sample different types in April, May, July and November, systematically test activity indexes as soluble sugar, soluble protein, free proline, contents of malonaldehyde and SOD, POD. Get a primary understanding of the changing rules of osmotic adjustment and protective enzyme activities of these three kinds of Amur honeysuckles. It shows that under the normal growing process, evergreen Amur honeysuckle and normal Amur honeysuckle have stronger abilities of osmotic adjustment, and evergreen Amur honeysuckle has the strongest abilities of protective enzyme activities among the three types.
