Title
Effect of Zinc Deficiency on the Accumulation of Boron and Other Mineral Nutrients in Barley
Robin D. Graham; Ross M. Welch; David L. Grunes; et al. Soil Science Society of America Journal 1987. doi:10.2136/sssaj1987.03615995005100030018x
Other claims from this paper (12)
- Intervention effect Barley seedlings without added Zn had B uptake rates 2 to 2.5 times those supplied Zn.
- Observation The Zn deprivation effect on B uptake appeared after 7 days.
- Mechanism The authors infer that Zn protects root-cell membrane surfaces or interiors.
- Intervention effect At extremely high nutrient-solution B, Zn protection disappeared.
- Observation All treatments developed B toxicity symptoms at extremely high B.
- Observation All treatments accumulated high B concentrations at extremely high B.
- Intervention effect Zn deprivation increased accumulation of P, NO 3 and S.
- Intervention effect Zn deprivation increased accumulation of Ca, Mg and K.
- Intervention effect Zn deprivation increased Cu accumulation.
- Intervention effect Fe was not accumulated under Zn deprivation.
- Intervention effect Higher solution P increased uptake rates of all ions, especially without Zn.
- Intervention effect Added P increased ion uptake in Zn-supplied plants, but less strongly.
