Effect of Aluminum Stress on Two Antioxidase(CAT and POD)in Eucalyptus spp.Seedlings
Lan Xiongbin;State-Owned Dongmen Forest Farm,Guangxi Zhuang Autonomous Region;
The effects of aluminum(Al)stress on CAT and POD of root and leaves for two superior clonal Eucalyptus spp.seedlings(Eucalyptus grandis × E.urophylla No.9and E.urophylla No.4,simplified as G9 G4)were studied by adopting indoor hydroponics test method.In order to further reveal the response mechanism of fastgrowing Eucalyptus spp.on Al toxicity and provide reference for selecting the excellent aluminum-resistant clones,the main result is follows:(1)the POD and CAT in the leaves of Eucalyptus spp.have the main effect on the scavenging activity of oxygen,and POD is the most sensitive to the treatment of CAT.(2)under the treatment of Al,the activities of CAT and POD in the roots and leaves of the two clones of Eucalyptus spp.changed;change width vary greatly;response degree of different parts for different enzymes are inconsistent;the response of CAT on aluminum treatment in the roots is very strong;the response of POD on aluminum treatment in the leaves of G9 and root of G4 is very strong.
