Other claims from this paper (7)
- Association Water-soluble phenolic acid content in compost extracts was negatively correlated with sorghum seed water uptake (r=-0.88).
- Association Water-soluble phenolic acid content was negatively correlated with sorghum seed α-amylase activity (r=-0.82).
- Intervention effect The acidic fraction of compost extracts containing phenolic acids inhibited sorghum germination.
- Intervention effect Commercial phenolic acid preparations reduced sorghum germination at concentrations above 50 mg L-1.
- Mechanism The authors considered phenolic acids a major group of germination inhibitors in animal-waste composts.
- Mechanism The authors indicated possible synergistic phenolic-acid effects in germination-inhibitory composts.
- Observation Non-phenolic germination inhibitors were also demonstrated in the composts.
