Petiole (Rachis) Blight of Palm
EDIS, 2019 In general, the “typical” or “classic” petiole blight is a disease in which the pathogen only infects the petiole. The disease symptoms may look like the pathogen has also infected the leaf blade, but this is a secondary affect from petiole infection ...

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.

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 ...

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.

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2022 Colletotrichum siamense infected the petiole and crown of strawberry (Fragaria × ananassa), and this anthracnose threatens strawberry production heavily in Hubei province. Characteristic the variation of transcript caused by C. siamense is important for

Leaf Pigments, Surface Wax and Spectral Vegetation Indices for Heat Stress Resistance in Pea
Agronomy, 2022 Pea is a grain legume crop commonly grown in semi-arid temperate regions. Pea is susceptible to heat stress that affects development and reduces yield. Leaf pigments and surface wax in a crop canopy make the primary interaction with the environment and ...

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.

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 ...
