Other claims from this paper (8)
- Observation A bimodal pattern of instantaneous curvature along the stem axis of Kalanchoë was detected at the end of the gravitropic response.
- Association Spatial and temporal growth oscillations appear to be overridden by local changes in growth rate in gravistimulated Kalanchoë stems.
- Intervention effect Rate of growth in Kalanchoë stems is initially depressed in response to reorientation in the gravitational field.
- Intervention effect Rate of growth in Kalanchoë stems is then stimulated after reorientation in the gravitational field.
- Association Growth rate is amplified on the lower side of gravistimulated Kalanchoë stems, with a basipetal migration.
- Association Growth rate returns to oscillatory on the upper side of gravistimulated Kalanchoë stems.
- Association Cell elongation potential is redistributed to the lower side of gravistimulated Kalanchoë stems.
- Association No evidence was found for overall enhancement of cell expansion in response to gravity in Kalanchoë stems.
