Other claims from this paper (6)
- Intervention effect Salinity inhibited cotton phosphate uptake more severely at low than high phosphate concentration.
- Observation At low phosphate concentration, uptake followed a Michaelis–Menten hyperbolic curve.
- Intervention effect NaCl increased apparent phosphate uptake Km from 2.23 to 4.73 μM.
- Intervention effect High NaCl inhibited phosphate uptake in the mature cotton root zone.
- Intervention effect Salinity enhanced phosphate uptake in cotton root tips.
- Intervention effect Salt treatment inhibited phosphate transport within cotton roots and from roots to shoots.
