Title
The Uptake of Phosphate by Plants from Flowing Nutrient Solution
V. G. BREEZE; M. J. HOPPER Journal of Experimental Botany 1987. doi:10.1093/jxb/38.4.618
Other claims from this paper (9)
- Intervention effect Phosphate concentration in solution had no effect on dry matter production or relative growth rate of white clover after 24 d
- Intervention effect Phosphate concentration in solution had no effect on root/shoot ratio or water soluble carbohydrate concentration of white clover after 24 d
- Intervention effect White clover supplied with nitrate yielded more than plants dependent on symbiotic nitrogen fixation
- Association Phosphate uptake by white clover was related to phosphate concentration in solution
- Intervention effect Source of nitrogen did not affect phosphorus concentrations in white clover shoots
- Intervention effect Roots of white clover dependent on symbiotically fixed nitrogen had higher phosphorus concentrations than roots of plants supplied with nitrate
- Intervention effect Amount of nitrogen fixed by white clover was unaffected by phosphate concentration in solution
- Observation Plants dependent on nitrogen fixation required hydroxyl ions equivalent to over 130 kg lime per tonne of dry shoot
- Mechanism Enhanced phosphate uptake by plants dependent on nitrogen fixation is suggested to result from a need for a cation-charge balancing anion
