SCLEREID DEVELOPMENT IN CAMELLIA PETIOLES

American Journal of Botany, 1982
Sclereid initials are distinguishable from neighboring cells by their large centralized nuclei. During the younger stages of development, they are densely cytoplasmic and have an abundance of cellular organelles—mitochondria, endoplasmic reticulum, Golgi bodies, and ribosomes.

Petiole Disease of Coconut in Papua.

The Papua New Guinea Journal of Agriculture, Forestry and Fisheries
A disease with dark brown lesions leading to frond break of coconut in Papua, caused by Anthostomella cylindrospora, is described. The control measures adopted against the disease, perhaps combined with a drought, have to date prevented any further occurrence of the condition. The area is being kept under close surveillance.

PETIOLE VASCULARIZATION OF LUXEMBURGIEAE (OCHNACEAE)

American Journal of Botany, 1967
Sections through the petiole and blade midrib and sometimes the node of 20 genera of Luxemburgieae have revealed variations in vascularization which appear significant in determining the phylogeny of the tribe. The most primitive group are the pentacarpellate genera; they are characterized by multilacunar nodes and numerous leaf ...

Fungal Decomposition of Bracken Petioles

The Journal of Ecology, 1969
Frankland (1966) described a succession of fungi on decaying petioles of bracken (Pteridium aquilinum (L.) Kuhn) in six habitats and tentatively ascribed chemical changes in the bracken to the action of certain predominant fungi. In the present investigation, some individual members of the fungal succession were grown on sterile bracken and changes in ...

The Mechanical Properties of Caladium Petiole

Strain, 2010
Abstract:  In this study, the mechanical properties of Caladium (Caladium × hortulanun Birdsey) petiole were investigated. The petiole was considered as a composite beam which consists of rind and core parts. To classify the mechanical properties of rind and core part of petioles, two‐phase three‐point bending tests were conducted on the specimens cut ...

Analysis of sugarbeet petioles for phosphorus

Communications in Soil Science and Plant Analysis, 1978
Abstract The influence of method of drying on concentrations of total P, extractable phosphate and two N fractions in petioles from recently matured sugarbeet leaves was studied. Method of drying had no or small effects on total P, total N and nitrate‐N. However, method of drying had a marked effect on the value of extractable phosphate. Concentrations
