Freeze-Drying of Plant Tissues

Nature, 1962
FREEZE-DRYING has proved a valuable technique in cytological investigations of animal cells and tissues, but it has not met with the same success when applied to plants1. Frozen-dried animal tissues are usually embedded in de-gassed paraffin wax which is later removed from the sections with xylol.

Vascular tissue development in plants

2019
The plant vasculature is a sophisticated system that has greatly contributed to the evolution of land plants over the past few hundred million years. The formation of the vascular system is a well-organized plant developmental process, but it is also flexible in response to environmental changes.

Hormone Profiling in Plant Tissues

2016
Plant hormones are for a long time known to act as chemical messengers in the regulation of physiological processes during a plant's life cycle, from germination to senescence. Furthermore, plant hormones simultaneously coordinate physiological responses to biotic and abiotic stresses.

Metabolomic Profiling of Plant Tissues

2015
Metabolomics is a powerful discipline aimed at a comprehensive and global analysis of the metabolites present in a cell, tissue, or organism, and to which increasing attention has been paid in the last few years. Given the high diversity in physical and chemical properties of plant metabolites, not a single method is able to analyze them all.Here we ...

Persistence of Alkaloids in Plant Tissue

Science, 1960
Under appropriate conditions of preservation, alkaloids can be detected in plant tissues after extended periods of time. A positive test for this class of compounds was given by a sample of plant material estimated to be 1300 years old.

The compression specificity of plant tissue

Journal of Texture Studies, 2020
AbstractThe aim of this study was to determine the compression characteristics of nonhomogeneous plant materials with a complex morphological structure (beetroots, celery roots, and potato tubers), to compare the analyzed samples with the compression characteristics of reference materials (homogeneous isotropic structural materials: steel coil spring ...

Histological methods for plant tissues

Journal of Histotechnology
Although many of the structures and organelles of vegetative cells are comparable to those of animal tissues, significant differences between the two kingdoms require modifications in histological techniques for both tissue processing steps and histochemical staining techniques.

Transport of Sodium in Plant Tissue

Science, 1965
Two mechanisms are implicated in the absorption of alkali cations by barley roots. Mechanism 1 has a high affinity for potassium, but its affinity for sodium is so low that, in the presence of even a low concentration of potassium (1 m M ), sodium absorption by this mechanism is all but abolished.

Light gradients in plant tissue

Applied Optics, 1983
In this paper we suggest a method for calculating light gradients in scattering and absorbing media. The method is based on the Kubelka-Munk theory and involves computational modeling of light fluxes in a multilayered object, when every layer satisfies the prerequisites of the Kubelka-Munk theory.

Plant Viruses in Tissue Culture

1967
Publisher Summary The chapter discusses on the plant viruses in the tissue culture. The tissue culture has played an ever-increasing role in practically every field of experimental biology. By means of this technique not only can the tissues of higher plants be grown in vitro , but the chemical and physical conditions of growth can be controlled at ...
