Other claims from this paper (13)
- Observation Superoxide dismutase activity peaked in embryonic axes after six hours of imbibition.
- Observation Peroxidase activities rose significantly after 12 hours and during phase III.
- Observation Catalase was the most efficient enzyme for catabolizing hydrogen peroxide in embryonic axes.
- Intervention effect Hot, humid storage caused soybean seeds to lose viability over time.
- Observation Cu, Zn-superoxide-dismutase activity increased in low-viability relative to high-viability seeds.
- Observation Mn superoxide dismutase activity increased to a lesser extent in stressed seeds.
- Mechanism Superoxide dismutase induction reflected transcript accumulation in response to superoxide production.
- Observation Catalase was not induced in low-viability seeds.
- Observation Zeatin riboside was abundant in high-viability seeds.
- Observation Zeatin riboside was oxidized to adenine in low-viability seeds.
- Observation Superoxide anion oxidized cytokinin in vitro.
- Observation Zeatin riboside scavenged superoxide anions, whereas adenine did not.
- Intervention effect Exogenous zeatin riboside partially restored stressed seed germination.
