- Intervention effect Fresh extracts of A. retroflexus reduced wheat seedling germination, coleoptile and root lengths, and root dry weight.
- Intervention effect Fresh extracts of A. blitoides reduced wheat seedling germination and growth traits.
- Intervention effect Fresh extracts of A. gracilis reduced wheat seedling germination and growth traits.
- Intervention effect Low concentrations of shoot extract promoted wheat shoot growth.
- Observation Fresh extracts were more phytotoxic than dried extracts.
- Intervention effect Dried A. gracilis shoot extract increased wheat seedling shoot and root dry weight in pots.
- Intervention effect A. retroflexus extracts and dried shoots significantly reduced wheat germination and growth in pots.
- Intervention effect A. blitoides extracts and dried shoots significantly reduced wheat germination and growth in pots.
- Intervention effect Up to 16 g kg −1 A. gracilis residues promoted wheat shoot growth.
- Intervention effect Up to 16 g kg −1 A. gracilis residues had no significant harmful effect on wheat root growth.
- Observation Wheat roots appeared more sensitive to allelopathy than shoots.
- Intervention effect Field incorporation of A. retroflexus residues reduced wheat height, grain and straw yield.
- Intervention effect Field incorporation of A. blitoides residues reduced wheat height, grain and straw yield.
- Intervention effect A. gracilis residues increased wheat height and yield in the field.
