Definizione

A slender stem- or petiole-like structure that is used by vines and lianas (climbing plants) to wrap around or to hook a support. 1

Nota

A tendril is a slender, whiplike or threadlike strand, produced usually from the node of a stem and composed of either stem or leafstalk tissue, by which a vine or other plant may climb. Sensitive to contact, the tendril turns toward any object it brushes against, wraps about it, and clings to it for as long as the stimulation persists. Later, strong mechanical tissue develops in the tendrils, making them strong enough to support the weight of the plant. Some tendrils have enlargements at the ends that flatten and produce an adhesive that firmly cements them to their support. Common examples of tendril plants are grape, English ivy, sweet pea, gourds, and passionflowers. 2

Contesto

For vines, tendrils are a cheap way to climb, but a tendrilar system does not hold great weight. 3
