Other claims from this paper (9)
- Intervention effect Phosphate starvation significantly reduced shoot and root mass to 8–11% of control after three weeks.
- Intervention effect Phosphate deprivation increased root to shoot fresh weight ratio two to threefold versus control.
- Intervention effect Phosphate deficiency reduced wheat shoot height to 50–60% of control after two to three weeks.
- Intervention effect Phosphate deficiency did not significantly alter root elongation in either cultivar during one to three weeks.
- Intervention effect Phosphate deficiency increased extracellular acid phosphatase activity relative to phosphate-sufficient plants.
- Intervention effect Phosphate deficiency increased intracellular acid phosphatase activity relative to phosphate-sufficient plants.
- Observation Intracellular phosphatase activity in leaves and roots increased more strongly in Bryza than Opatka.
- Observation Root surface acid phosphatase activity increased most for phosphate deficient Bryza after three weeks.
- Observation Root secreted acid phosphatase activity rose more than intracellular activity under phosphate deficiency.
