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.
Association Hyperhydricity followed endogenous superoxide generation and coincided with H2O2 accumulation.
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 With H2O2 plus AsA, SOD, POD and CAT activities continued to rise and exceeded H2O2 alone and control later.
Intervention effect Endogenous AsA remained high and exceeded H2O2 treatment.
Intervention effect Garlic hyperhydricity rose slowly and was significantly lower under H2O2 plus AsA than H2O2 alone.
Mechanism The authors attribute increased hyperhydricity under H2O2 to reduced antioxidant capacity.
Mechanism The authors conclude that added AsA controls hyperhydricity by relieving reactive oxygen accumulation.
