Influência do desponte sôbre a composição do colmo e do caldo da cana-de-açúcar: III. Var. CB 41-76

I. This paper deals with an experiment carried out to evaluate the effect of sugar cane upper end on the composition of the stalks and juice of sugar cane harvest as a raw material for the sugar industry. The variety studied was CB 41-76. The data were collected from plant cane at intervals of a two weeks, always from the same field, from a small central area of 3.000 square meters approximately, 60 stalks were cut in each occasion, randomly chosen from the whole area. They were afterwards separated into three groups of 20 stalks one for each of the treatments, namely: a) Complete stalk, with no leaves or sheaths. b) Stalks harvested by the technique of REYNOSO, that is, as usually done in practice. c) Stalks with the tops completely cut out, that is, cut by the techinique of REYNOSO and then with 3 other top internodes eliminated. The treatments caused significant differences on the weight of cane and coefficient of purity of juice, but the percentual differences between the average treatments a and c is 13% and 2%, respectively. II. Treatment differences for cane pol, cane fibre, brix, juice pol, reducing sugars, juice ashes, glucose coefficient, saline coefficient and available sucrose (pol) per cent were not significant. III. Time of harvest was an important factor affecting the composition of the cane and the juice. This paper shows that there is no sound basis for the heavy fines applied some sugar mills to planters who do not cut low enough the tops of the cane stalks.

Deficiência de macro e micronutrientes em cana-de-açúcar (Saccharum officinarum spp) variedade CB 41-76 cultivada em solução nutritiva

Mudas de cana-de-açúcar (Saccharum officinarum spp) cultivar CB 41-76 foram cultivadas em soluções nutritivas, omitindo - se por vez o N, P, K, Ca, Mg, S, B, Cu, Fe, Mn, Mo e Zn, com os seguintes objetivos: 1. Obter um quadro sintomatológico da morfologia externa e morfologia interna em função das carências; 2. Verificar o efeito da presença e omissão dos macronutrientes na composição química das folhas (+1, +2, +3); (+4, +5, +6); (+7, +8, +9) e nas bainhas (+4, +5, +6). Foram constatados e descritos os sintomas de carência dos macro e micronutrientes. As partículas subcelulares mais afetadas pelas carências foram os cloroplastos das células da bainha envolvente dos feixes libero lenhosos e do parênquima paliçadico adjacente ao limbo. Níveis nas folhas de plantas sadias e deficientes, expressos em porcentagem na materia seca, foram.

Chagas disease in Mexico: an analysis of geographical distribution during the past 76 years - A review

Literature from 1928 through 2004 was compiled from different document sources published in Mexico or elsewhere. From these 907 publications, we found 19 different topics of Chagas disease study in Mexico. The publications were arranged by decade and also by state. This information was used to construct maps describing the distribution of Chagas disease according to different criteria: the disease, vectors, reservoirs, and strains. One of the major problems confronting study of this zoonotic disease is the great biodiversity of the vector species; there are 30 different species, with at least 10 playing a major role in human infection. The high variability of climates and biogeographic regions further complicate study and understanding of the dynamics of this disease in each region of the country. We used a desktop Genetic Algorithm for Rule-Set Prediction procedure to provide ecological models of organism niches, offering improved flexibility for choosing predictive environmental and ecological data. This approach may help to identify regions at risk of disease, plan vector-control programs, and explore parasitic reservoir association. With this collected information, we have constructed a data base: CHAGMEX, available online in html format.
