Other claims from this paper (17)
- Intervention effect Increasing subsoil extractable B did not reduce subsoil water use by barley grass or evening primrose.
- Intervention effect Symptoms of B toxicity in shoots of all species appeared at subsoil-extractable B of 12.2 mg/kg.
- Intervention effect Symptoms of B toxicity in shoots also appeared at lower subsoil B concentrations in some crop and weed species.
- Intervention effect Shoot growth, total water use and topsoil root growth of barley cultivar Clipper were severely impaired by high subsoil-extractable B.
- Intervention effect Shoot growth, total water use and topsoil root growth of Lincoln weed were severely impaired by high subsoil-extractable B.
- Association In the weed species the reduction under high subsoil B was mostly associated with a decrease in taproot dry weight.
- Intervention effect Topsoil root growth of evening primrose was severely impaired by high subsoil-extractable B.
- Intervention effect Barley grass, VB9953 and evening primrose maintained shoot growth at all subsoil-extractable B concentrations.
- Intervention effect Fababean and prickly lettuce maintained shoot growth at all subsoil-extractable B concentrations, to a lesser extent.
- Association Subsoil water use by breeders line VB9953 was reduced despite its shoot growth being maintained.
- Intervention effect Prickly lettuce and VB9953 sustained root growth in the topsoil under high subsoil extractable B.
- Intervention effect Fababean and barley grass increased topsoil root growth in response to high subsoil extractable B.
- Association There was no direct relationship between shoot B accumulation and detrimental effects on growth.
- Association Water uptake and B uptake showed no direct relationship, irrespective of the effect of subsoil B on water use.
- Association Shoot B concentration increased as subsoil B increased, in all species and genotypes.
- Association The degree of tolerance shown by plants depended strongly on the trait used for assessment.
- Recommendation Shoot dry matter in B toxic soil can be a consistent parameter for considering varieties for tolerance to B toxicity.
