Do some vines grow toward a support?

Details

Climbing plants need an external support to grow upward and gain better access to light. The review describes vines that find suitable supports as performing better and having greater success in survival and reproduction than vines that remain along the ground.

Rather than reporting a new experiment, the author reviews studies of how climbing plants find and use supports. These include cases of growth directed toward supports. The review also considers how the characteristics of supporting trees may affect whether different kinds of climbers successfully establish themselves on those trees. Separately, it examines evidence about environmental and genetic influences on circular growth movements and changes in plant traits in response to support availability. These topics should not be taken as proof of how vines grow toward a support.

The abstract gives no species-specific methods or results for directed growth, and it does not report a comparison of supports at different distances. It supports the existence of such cases, not a universal ability or a particular detection mechanism. The author proposes applying theories used to study animal behaviour to investigate the costs and benefits of support finding, while emphasizing that its ecological causes and consequences remain less studied than its mechanics.
