A low-viscosity epoxy resin embedding medium for electron microscopy.
- A. Spurr
- Materials Science, MedicineJournal of ultrastructure research
A low-viscosity embedding medium based on ERL-4206 is recommended for use in electron microscopy and has a long pot life of several days and infiltrates readily because of its low viscosity.
CHROMOPLASTS OF TOMATO FRUITS. II. THE RED TOMATO
Comparisons of the mature chromoplasts of the normal red tomato with those of other pigment lines indicate that differences in carotenoids markedly affect ultrastructure, and the relationship between lycopene and chromoplast structure and the effect of genes controlling fruit pig is determined.

CHROMOPLASTS OF TOMATO FRUITS. I. ULTRASTRUCTURE OF LOW‐PIGMENT AND HIGH‐BETA MUTANTS. CAROTENE ANALYSES
Three pigment lines of the tomato cultivar 'Pearson' with isogenic backgrounds were studied to determine the relationship between certain carotenoids and the development of chromoplasts during fruit ripening and the ultrastructural changes in plastids of the two mutant lines.
Responses of lettuce to salinity. I. Effects of NaCl and Na2SO4 on growth
Two lettuce cultivars were selected to compare their tolerance to salt stress and Climax showed a greater tolerance to salinity at the 40 mol m–3 NaCl concentration; the % decrease in both shoot and root fresh weight was significantly less than Calmar.
ULTRASTRUCTURE OF CHLOROPLASTS AND CHROMOPLASTS IN CAPSICUM ANNUUM I. THYLAKOID MEMBRANE CHANGES DURING FRUIT RIPENING
Salt reponses of lettuce to salinity. II. Effect of calcium on growth and mineral status
Abstract The effect of Ca2+ on the salt tolerance of two lettuce cultivars (Lactuca sativa L. cv. Calmar and cv. Climax), differing in their salt tolerance, was investigated. The plants were grown in…
THE EFFECT OF BORON ON CELL‐WALL STRUCTURE IN CELERY
- A. Spurr
- 1 October 1957
A large body of evidence showing that under a deficiency of boron abnormally large amounts of carbohydrates accumulate in the plant is referred to, and a study of the cell walls of plants grown at different levels of bOron is needed.
Isolation of active mitochondria from tomato fruit.
Electron microscope studies show that this method gives homogeneous, relatively intact mitochondria; they have a higher respiratory control ratio than those reported by other workers.
Electron probe analysis of freeze-substituted, epoxy resin embedded tissue for ion transport studies in plants
The lateral transport of K+ into the xylem of corn roots has been successfully studied by electron probe analysis of freeze-substituted, epoxy resin embedded material.
