Antigens and antisera from in vitro cultures of Puccinia melanocephala Sydow, uredospores collected from the field and sugar cane varieties were obtained. Cross-reactions were detected between the fungi and plants by counterimmunoelectrophoresis, immunoelectrophoresis and indirect ELISA. The last technique detected more antigenic relationships with the susceptible plants. This result may be use...

The genus Saccharum consists of two wild and four cultivated species. Novel interspersed sequences were isolated from cultivated sugar cane S. officinarum. These sequences were accumulated in all four cultivated species and their wild ancestral species S. robustum, but were not detected in the other wild species S. spontaneum and the relative Erianthus arundinaceus. The species-specific accumul...

using productivity index for investigating a firms’ performance makes it possible to evaluate efficiency of the production system and cost at the same time. in this study the total factor productivity (tfp) of several sugar cane varieties in imam khomeini cultivation and processing center in khuzestan province is compared. two hundred and forty eight farms are categorized on the basis of variet...

The objectives of this study were to determine (a) the influence of fiber on the sensory characteristics of dry dog foods; (b) differences of coated and uncoated kibbles for aroma and flavor characteristics; (c) palatability of these dry dog foods; and (d) potential associations between palatability and sensory attributes. A total of eight fiber treatments were manufactured: a control (no fiber...

The application of ion-exclusion chromatography to desugarization of molasses has been investigated in the beet sugar industry for many years and is now being applied routinely to sucrose recovery. Recent work on the desugarization of molasses from cane processing has been carried out and a large-scale system is under construction. Ion-exclusion chromatographic processes are very efficient for ...

Metarhizium anisopliae is used as a biopesticide for insects that damage agricultural plantations like sugar cane and forage plants. In a previous study the sensitization to this fungus of asthmatic patients coming from sugar cane areas was showed. The aims of this work were: to compare crude extracts obtained with Tris-HCl and Coca liquid from several growth phases of M. anisopliae concerning ...

With crude oil prices approaching $100 a barrel this autumn, following one of the worst global harvests in recent history, the idea that crops may be able to provide biofuels is one of the most contentious current agri-industrial topics. And it is presently having the greatest impact in the tropics, where ecosystems are already under unprecedented threat from human activity. Conservationists ar...

The treatments consisted of chopping sugar cane stalk coarsely (10 to 20 mm particle size) or finely (less than 5 mm). The chopped cane stalk was mixed with chopped cane tops ( 40 to 50 mm particle size) in the ratio 75: 25. A solution of urea/molasses (200 g urea/kg solution) was added to the cane at the rate of 50 g/kg of fresh cane. The animals also received 600 g/d cotton seed meal and 100 ...
