Other claims from this paper (8)
- Intervention effect At 0.04-0.12%, Cu-chitosan nanoparticles increased shoot and root length, root number and seedling length relative to comparator treatments.
- Intervention effect At 0.04-0.12%, Cu-chitosan nanoparticles increased fresh and dry weight relative to comparator treatments.
- Intervention effect Cu-chitosan nanoparticles induced α-amylase and protease activities in germinating maize seeds.
- Intervention effect Cu-chitosan nanoparticles increased total protein content in germinating maize seeds.
- Association Higher enzyme activities coincided with decreased starch and protein content in germinating seeds.
- Intervention effect Cu-chitosan nanoparticles at 0.16% inhibited seedling growth.
- Intervention effect CuSO4 at 0.01% inhibited seedling growth.
- Mechanism The authors attribute maize seedling growth promotion to reserve starch mobilization through greater α-amylase activity.
