Other claims from this paper (9)
- Association Sucrose concentration shifts the IAA concentration for maximum pea epicotyl elongation across at least three orders of magnitude.
- Intervention effect High IAA inhibited elongation only with sucrose.
- Intervention effect Sucrose promoted water uptake.
- Association Sucrose affected the IAA optimum for water uptake only slightly.
- Observation IAA growth action was detectable immediately.
- Observation The sucrose growth response followed a 6–8 hour lag.
- Intervention effect IAA with sucrose inhibited elongation in hours 1–3.
- Intervention effect IAA with sucrose was relatively inactive on elongation in hours 4–6.
- Intervention effect IAA with sucrose strongly promoted elongation after hour 7.
