Other claims from this paper (10)
- Intervention effect A-HA1–1 at 2.5–10 mg/L significantly increased maize biomass by 13.8 %–24.1 %.
- Intervention effect A-HA1–1 at 2.5–10 mg/L significantly increased maize N uptake by 13.8 %–25.0 %.
- Mechanism Increased root plasma membrane H + -ATPase activity was attributed as contributing to maize growth and N uptake increases.
- Mechanism Enhanced nitrate ion influx into root cells was attributed as contributing to maize growth and N uptake increases.
- Intervention effect A-HA promotion of maize growth decreased as extraction alkali concentration rose from 1 % to 10 %.
- Mechanism The reduced proportion of low-molecular-weight components was attributed as the main reason for lower A-HA activity.
- Intervention effect A-HA precipitated at pH 3 stimulated maize growth more than A-HA precipitated at pH 1.
- Mechanism Higher contents of O-alkyl-C, O-substituted aromatics-C, carboxylic-C, and amide-C were attributed as the reason for greater activity of pH 3 precipitate.
- Recommendation The authors recommend controlling alkali concentration and precipitation pH when preparing A-HA for maize stimulation.
- Observation A-HA made with 1 % alkali and precipitated at pH 3 was described as optimal for stimulation.
