Abstract

Participation of light in modification of peroxidase enzymatic system activity and peroxide hydrogen generation in the wheat seedlings shoot and root endocellular compartment is revealed. It is shown that in elevated parts of seedlings light activates oxidase peroxidase function and causes peroxide hydrogen accumulation (oxidative burst); in roots – light induces equivalent changes of both enzymatic functions, without causing change of ROS level.
