Abstract:
Using chrysanthemum ‘Nannong Gongfen’ as experiment material,the influence of different light conditions on plant morphology and antioxidant were researched.The results showed that leaf color under full sunlight was yellowish-green,and that leaf area in 15% irradiance became bigger.The activities of superoxide dismutase (SOD,EC 1.15.1.1),monodehydroascorbate reductase (MDAR,EC 1.6.5.4),glutathione reductase (GR,EC 1.6.4.2),ascorbate peroxidase (APX,EC 1.11.1.11),superoxide anion (O2.) generation rate and malondialdehyde (MDA) content increased at the fourth day.By 18 days,MDA content decreased to the lower level.The results showed that antioxidant enzymes provided effective protection from oxidative damage.The maintained high level O2. was caused by excess light energy.
