Geotropic bending is associated with:
Answer: B
Geotropic bending is associated with gladiolus: the flower spike curves upward when the plant lies horizontal, because the spike is negatively geotropic. This is a known problem in cut gladiolus, which is stored upright.
Marigold, jasmine and China aster are not known for this.
Gladiolus is known for spikes that bend upward when the stems are laid flat, because the stem tip grows against gravity (negative geotropism). Cut spikes are therefore stored and shipped upright.
