Title

Changes of Reactive Oxygen Metabolism of Garlic Plantlet in Vitro Under Exogenous H_2O_2 Stress and the Responses to AsA

Lin Zhang Acta Horticulturae Sinica 2011

Other claims from this paper (12)

Intervention effect Exogenous H2O2 increased hyperhydricity rate and degree.

Intervention effect During days 0 to 8, SOD, POD and CAT activities rose above the control.
Observation After day 8, SOD and CAT activities decreased.
Observation After day 8, POD activity increased slowly.
Intervention effect Endogenous AsA content on day 8 was lower than control.
Intervention effect H2O2 plus AsA reduced superoxide production and H2O2 content relative to H2O2 alone.

Intervention effect MDA content increased significantly during cold acclimation.
Intervention effect Cold acclimation markedly increased dehydrin transcript levels.
Intervention effect Cold acclimation markedly increased beta-glucosidase transcript levels.
