e1“Gravitropic response of Kalanchoë stems was analyzed in terms of instantaneous curvature along the stem, relative elemental growth rates, and epidermal cell dimensions”
e6“There is a basipetal migration in amplified growth rate on the lower side and a return to oscillatory growth rate on the upper side of gravistimulated stems”

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.
- Observation Growth-rate oscillations in Kalanchoë stems showed complex spatial and temporal patterns in both gravistimulated and unstimulated control stems.
- 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 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.
