Forty-third Conference the Use of Phase-contrast Microscopy in the Identification of Ratoon Stunting Disease
نویسنده
چکیده
Four methods used for the identification of ratoon stunting disease have been described previously (Steindl and Teakle 1974) and the relative merits of these methods discussed. An additional method using phase-contrast or dark-field microscopy has also been described (Gillaspie, Davis and Worley 1973). In view of the fact that this can be carried out in approximately the same time as the electron microscope method, but with much less expensive equipment, it was decided to test phase contrast under Queensland conditions, using the extraction technique developed for electron microscopy.

Some Observations on the Bacterium Associated with Ratoon Stunting Disease of Sugarcane
The consistent association of a bacterium with ratoon stunting disease (RSD) has been confirmed in South Africa by phase contrast and electron microscope examination of sugarcane tissue diffusates from a wide range of varieties. The bacterium is rod shaped, often curved and measures approximately 1,O-4,O pm x 0,2-0,3 ym. Bacteria appear to be systemic within plants affected by RSD, but are most...
متن کاملRatoon stunting disease of sugarcane: isolation of the causal bacterium.
A small coryneform bacterium was consistently isolated from sugarcane with ratoon stunting disease and shown to be the causal agent. A similar bacterium was isolated from Bermuda grass. Both strains multiplied in sugarcane and Bermuda grass, but the Bermuda grass strain did not incite the symptoms of ratoon stunting disease in sugarcane. Shoot growth in Bermuda grass was retarded by both strains.
متن کاملDifferentiation of Glomerular from Non-Glomerular Hematuria by Three Different Me-thods of Microscopic Examinations of Erythrocytes in Urine
Background: Morphological examinations of urinary erythrocytes can be of diagnostic value in initial evaluation of hematuria. Dysmorphic urinary red blood cells are known to indicate a glomerular origin of bleeding. We examined the clinical usefulness of this test in a population complained of hematuria by use of three different methods: light microscopy, phase contrast microscopy, and Wright s...
متن کاملEffect of Ratoon Stunting Disease on the Yield and Components of Yield of Sugarcane under Rainfed Conditions
In a field trial conducted with eight varieties in the north coast area of Natal ratoon stunting disease (RSD) caused increasing lossesin yieldsof cane and sucrosefrom the plant to the second ratoon crop. All the varieties suffered losses in yield but the degree of loss differed markedly among the varieties. The total yield of sugar from the three crops was reduced by 38% in varieties NCo 376an...
متن کاملRapid Spread of Ratoon Stunting Disease during Manual Harvesting of Sugarcane and the Effect of Knife Cleaning on the Rate of Spread
In a field experiment, spreader plants of variety N13 infected with ratoon stunting disease were interplanted with healthy plants of indicator variety NC0376. When cane knives were not disinfected during manual harvesting, 62% ofstalks ofNC0376 down-row from the spreader plants were found to be infected after one harvest, and almost all the stalks were infected after three harvests. This compar...
