Other claims from this paper (8)
- Association The IAA concentration for maximum elongation shifted from about 10–4 M without sucrose to 10–7 M at 2% sucrose.
- Intervention effect High IAA inhibited elongation only with sucrose present.
- Intervention effect Sucrose promoted water uptake.
- Association Sucrose affected the IAA optimum for water uptake only slightly.
- Observation IAA action on growth was immediate, while sucrose response began after a 6–8 hour lag.
- Intervention effect With sucrose, one-hour IAA exposures could match continuous 20-hour exposure for growth depending on timing.
- Intervention effect At 2% sucrose, 10—4 M IAA inhibited elongation in hours 1–3.
- Intervention effect At 2% sucrose, 10—4 M IAA promoted elongation after hour 7.
