Since growth is a complex developmental procedure, there are indeed many requirements (both biotic and abiotic) that are needed for both touch perception and a thigmotropic response to occur. One of these is calcium. In a series of experiments in 1995 using the tendril Bryonia dioica, touch-sensing calcium channels were blocked using various antagonists. Responses to touch in treatment plants which received calcium channel inhibitors were diminished compared to contro… WebThe thigmotropism mechanism results in the opening, closing and twisting of petals and leaves in some plants. Tendrils and twiners show thigmotropism. Differential and rapid contact coiling are the two common forms of thigmotropism. Specialized epidermal cells bring differential growth.
