- Observation D-mannose made up 29.21% of the carbohydrates in the aqueous leaf crude extract of Avicennia marina by GC-MS.
- Observation D-fructose made up 18.51% of the carbohydrates in the aqueous leaf crude extract of Avicennia marina by GC-MS.
- Observation L-sorbose made up 12.91% of the carbohydrates in the aqueous leaf crude extract of Avicennia marina by GC-MS.
- Observation D-galactose made up 5.47% of the carbohydrates in the aqueous leaf crude extract of Avicennia marina by GC-MS.
- Observation D-Talose made up 5.21% of the carbohydrates in the aqueous leaf crude extract of Avicennia marina by GC-MS.
- Method / resource Ultra-fine nanoparticles of 11.60 ±4.65 nm comprising Cu2O and Cu(OH)2 were obtained from the extract.
- Method / resource The biogenic Cu nanoparticles had carbohydrate and phenolic contents of 35.6±3.2% and 3.13±0.05 mgGA/g, respectively.
- Intervention effect The impact of the biogenic Cu NPs on wheat seedling growth was dose-dependent.
- Intervention effect Treatment with 0.06 mg/mL Cu NPs promoted wheat root growth by 172.78 ± 23.11%.
- Intervention effect Treatment with 0.06 mg/mL Cu NPs promoted wheat shoot growth by 215.94 ± 37.76%.
- Intervention effect At 0.43 mg/mL Cu NPs the relative growth of wheat root was lowest, 81.94 ± 11.70%.
- Intervention effect At 0.43 mg/mL Cu NPs the relative growth of wheat shoot was lowest, 72.46 ± 18.78%.
- Intervention effect At 0.43 mg/mL Cu NPs, peroxidase activity of the germinated wheat seeds decreased.
- Intervention effect At 0.43 mg/mL Cu NPs, ascorbic acid oxidase and polyphenol oxidase activities of the germinated wheat seeds increased.
- Observation Copper uptake was higher in wheat root than in shoot.
- Observation Copper uptake from the biogenic Cu NPs was higher than from commercial Cu NPs.
- Intervention effect Commercial Cu NPs had an insignificant effect on wheat seedling growth.
- Intervention effect The high concentration (0.43 mg/mL) of Cu NPs was most effective in reducing wheat leaf chlorophyll a, b and total content after 21 days.
- Recommendation The authors conclude that controlled doses of the biogenic Cu NPs could be used to inhibit or stimulate seedling growth.
