Large quantities of cassava common mosaic virus (CCMV) were purified from systemically infected Nicotiana benthamiana plants. A polyclonal antiserum, with a titre of 1/128 in the tube precipitin test, was produced by immunising rabbits with purified virus. Viral antigens were detected in cassava,...

To determine the presence of Kranz anatomy, chloroplast structure and distribution in cassava leaf tissues, a selection was made among materials of CIAT`s germplasm bank. Two materials were selected, var. MCol 22 and hybrid CM 507-37; work was also carried out with maize var. Swan Laposta C48B (m...

Cassava, bean, and maize leaves were fed with (14)CO2 in light; the primary products of photosynthesis were identified 5 and 10 s after assimilation. In cassava, approx. 40-60 percent were incorporated in C4 acids with 30-50 percent in phosphoglyceric acid, which indicates that cassava possesses ...

Phyllody, previously unreported in Brazil, was observed in several cassava cv. and hybrids planted in exptl. plots of the Centro Nacional de Pesquisa de Mandioca e Fruticultura in Cruz das Almas. The effect of the disease on production is not known; however, it poses a serious threat to the cassa...

Two levels of CM substitution (25 and 50 percent) for industrial concentrate were studied; 3 treatments (with broiler chicks randomly assigned to blocks) during fattening were compared with a check treatment (100 percent industrial concentrate). Slaughter wt. over 1.5 kg/animal were obtained, wit...

A technique to study mycorrhizal effects on growth and P-uptake of cassava (Manihot escultenta, Crantz) grown in flowing solution culture is described. Phosphorus concentrations were carefully maintained constant at 0.1, 1, 10 and 100 ?M by daily analyses and adjustment of the nutrient solutions....

The parasitism, development, and thermal requirements of Trichogramma exiguum and Telenomus sphingis, common parasitoids of Erinnyis ello eggs, were studied. Life statistics were also determined for each specie and temp. (20, 25, and 30 degrees C for both species; for T. sphingis 32.5 degrees C w...

Greenhouse studies on pathogenic variability of Xanthomonas manihotis did not reveal the occurrence of distinct pathogenic races. The non-race status of the pathogen suggests that CBB could be well-controlled in the field by using known levels of genotype resistance in specific ecosystems and by ...
