Section properties of palm petioles, Part 1: The influence of section shape on the flexural and torsional properties of selected palm petioles [PDF]

, 2008
Shape factors have been used to calculate the shape efficiency of palm leaf petiole sections in order to understand how palms compensate for the torsional and bending forces put upon them by their environment.

Section properties of palm petioles, part 2: The relationship of petiole histology with the torsional rigidity of the palm, Trachycarpus fortunei [PDF]

, 2006
The Trachycarpus fortunei palm is a good example of a palm with a large leaf blade supported by a correspondingly large petiole. The interaction of the material and functional properties of the petiole was analysed using engineering and botanical methods

Scaling relationships and vessel packing in petioles [PDF]

American Journal of Botany, 2018
Premise of the StudyWhile tradeoffs among mechanical and conductive functions have been well investigated in woody stems, these tradeoffs are relatively unexplored in petioles, the structural link between stems and laminas. We investigated size‐independent scaling relationships between cross‐sectional areas of structural and vascular tissues ...

The tissue structure of the vegetative organs of strawberry (Fragaria moschata Duch®)

International Journal of Horticultural Science, 2000
The tissue structure of the vegetative organs of strawberry (root, rhizome, stolon, leaf) is discussed in this paper. The authors stated that the root structure described by Muromcev (1969) and Naumann-Seip (1989) develops further from the primary ...

A Comparison of Petiole Hydraulics and Aquaporin Expression in an Anisohydric and Isohydric Cultivar of Grapevine in Response to Water-Stress Induced Cavitation

Frontiers in Plant Science, 2017
We report physiological, anatomical and molecular differences in two economically important grapevine (Vitis vinifera L.) cultivars cv. Grenache (near-isohydric) and Chardonnay (anisohydric) in their response to water-stress induced cavitation.

Embolism resistance in petioles and leaflets of palms [PDF]

Annals of Botany, 2019
AbstractBackground and aimsHydraulic studies are currently biased towards conifers and dicotyledonous angiosperms; responses of arborescent monocots to increasing temperature and drought remain poorly known. This study aims to assess xylem resistance to drought-induced embolism in palms.MethodsWe quantified embolism resistance via P50 (xylem pressure ...

Photosynthetic contribution and characteristics of cucumber stem and petiole [PDF]

BMC Plant Biology, 2021
Abstract Background Photosynthesis of plant non-leaf blade green tissue has been studied in some plants, but the photosynthesis characteristics of stem and petiole are poorly understood. Cucurbitaceous plants are climbing plants, and have a large biomass of stem and petiole.

Metabolism of Tryptophan in Petioles of Coleus [PDF]

Plant Physiology, 1966
Auxin precursors retard abscission when applied to debladed petioles of Coleus blumei Benth. The d and l forms of tryptophan are equally effective in retarding abscission. Tryptamine is more effective than is tryptophan. Both compounds apparently are converted to auxin through an aldehyde intermediate.
