Abstract
The effects of different Al concentrations( 0,20,100,400 μmol /L) and different treatment time( 0,3,6,12,24 h) on root tips growth,reactive oxygen concentrations and antioxidant enzyme activities of peanut varieties ZH2( Al-sensitive) and 99-1507( Al-tolerant) were studied. The results showed that Al concentration above 100 μmol / L could inhibit peanut root tip growth and induce oxidative burst significantly. Oxidative burst peek appeared earlier with Al concentration increasing. Oxidative content was significant higher in ZH2 than in 99-1507. With increasing Al concentration and treatment time,MDA contents and SOD activities increased. The increment was higher in ZH2 than in 99-1507. The activities of POD and CAT increased firstly,and then kept stably. APX activity decreased gradually. The activities of POD,CAT and APX in 99-1507( Al-tolerant) were higher than in ZH2( Al-sensitive). It was suggested that Al could induce oxidative burst and oxidative stress within short time in peanut. The difference of oxidative resistance activity maybe one of the important Al resistant mechanisms.
