Leaf damage induces twining in a climbing plant.
Successful climbing by vines not only prevents shading by neighbouring vegetation, but also may place the vines beyond ground herbivores. Here we tested the hypothesis that herbivory might enhance climbing in a vine species, and that such induced climbing should be greater in the shade. We assessed field herbivory in climbing and prostrate ramets of the twining vine Convolvulus arvensis. We eva...
متن کاملLeaf Mimicry in a Climbing Plant Protects against Herbivory
Mimicry refers to adaptive similarity between a mimic organism and a model. Mimicry in animals is rather common, whereas documented cases in plants are rare, and the associated benefits are seldom elucidated [1, 2]. We show the occurrence of leaf mimicry in a climbing plant endemic to a temperate rainforest. The woody vine Boquila trifoliolata mimics the leaves of its supporting trees in terms ...
متن کاملMechanics of climbing and attachment in twining plants.
Twining plants achieve vertical growth by revolving around supports of different sizes on which they exert a pressure. This observation raises many intriguing questions that are addressed within the framework of elastic filamentary structures by modeling the stem close to the apex as a growing elastic rod. The analysis shows that vertical growth is achieved thanks to discrete contact points and...
متن کاملLeaf Area, Light Transmission, Roots and Leaf Damage in Nine Tropical Plant Communities
Ewel, J., Gliessman, S., Amador, M., Benedict, F., Berish, C., BermfJdez, R., Brown, B., Martfnez, A., Miranda, R. and Price, N., 1982. Leaf area, light transmission, roots and leaf damage in nine tropical plant communities. Agro-Ecosystems, 7: 305--326. The vertical distribution of leaf area by species; transmission of photosynthetically active radiation; root biomass and fine-root surface are...
متن کاملDelayed leaf senescence induces extreme drought tolerance in a flowering plant.
Drought, the most prominent threat to agricultural production worldwide, accelerates leaf senescence, leading to a decrease in canopy size, loss in photosynthesis and reduced yields. On the basis of the assumption that senescence is a type of cell death program that could be inappropriately activated during drought, we hypothesized that it may be possible to enhance drought tolerance by delayin...
