Hydrogen peroxide scavenging regulates germination ability during wheat (Triticum aestivum L.) seed maturation.

ABSTRACT: Hydrogen peroxide (H(2)O(2)) promotes seed germination of cereal plants and ascorbic acid which acts as antioxidant suppresses the germination of wheat seeds, but the role of H(2)O(2) scavenging on germination during seed maturation has not been demonstrated. We investigated relationship of germination, ascorbate, H(2)O(2) scavenging enzymes and sensitivity to ascorbic acid (AsA) maturing seeds of two typical wheat (Triticum aestivum L.) cultivars, cvs. Shirogane-Komugi and Norin61. Shirogane-Komugi had marked high germination ability than Norin61 during seed maturation. Although the H(2)O(2) content had no difference in the two culti-vars, sensitivity to AsA of Norin61 seeds was higher than that of Shirogane-Komugi seeds during seed maturation. The sensitivity to AsA closely correlated wi
