Study on Alkali-tolerance of Cinnamomum camphora from Different Provenance

The Cinnamomum camphora seedlings from 5 provenances were transplanted on the same soil mediums(pH8.1).5 indices(plant height,content of proline,content of chlorophy II,SOD activity and active iron content) were measured after 5 months.The resistances of the 5 Cinnamomum camphora provenances were evaluated by index integration.
