Petiole-Lamina Transition Zone: A Functionally Crucial but Often Overlooked Leaf Trait

Plants, 2021
Although both the petiole and lamina of foliage leaves have been thoroughly studied, the transition zone between them has often been overlooked. We aimed to identify objectively measurable morphological and anatomical criteria for a generally valid ...

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.

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 ...

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 ...

Functional Mapping of Genes Modulating Plant Shade Avoidance Using Leaf Traits

Plants, 2023
Shade avoidance syndrome (SAS) refers to a set of plant responses that increases light capture in dense stands. This process is crucial for plants in natural and agricultural environments as they compete for resources and avoid suboptimal conditions ...

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

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 ...

Delivery of Hairpin RNAs and Small RNAs Into Woody and Herbaceous Plants by Trunk Injection and Petiole Absorption

Frontiers in Plant Science, 2018
Since its discovery, RNA interference has been widely used in crop protection. Recently, transgene-free procedures that were based on exogenous application of RNA molecules having the capacity to trigger RNAi in planta have been reported.

Kinetics of Abscission in the Bean Petiole Explant [PDF]

Plant Physiology, 1969
The progress of bean petiole abscission has been followed using quantitative measurements of the mechanical force required to break explants at the separation zone. It is found that the shortest time for a measurable effect of ethylene (1 ppm) in stimulating the development of frangibility is about 1 hr.
