Abstract: for the brazilian conditions, the determination of the quality of a potato field, grown for seed purposes cannot be done based only in field inspections. a post control method is already recommended, based on the removal of spheric seed pieces from the crown end of tuber samples and their planting for further determination of their phytosanitary quality. in order to determine the best way for breaking the dormancy of seed pieces of the cv. aracy (iac-2) a late cultivar, which ought produce plants of easy determination of secondary infection with the potato leafroll virus (plrv), a trial was carried out with six treatments in 1983, at tietê, state of s?o paulo, brazil. the treatments were: 1 - check control; 2 - whole tubers treated with cs2 (30 cc/m3 of chamber during 48 hours) and posterior removal of the eyes; 3 - immersion of the seed pieces in a solution containing 1 ppm of gibberellic acid (g.a.); 4 - the same, in a 2 ppm g.a solution; 5 - treatment 2 plus treatment 3; and 6 - treatment 2 plus treatment 4. the treatment 5 gave the best results. it is discussed the influente of the seed piece treatment in the percentage of a perfect stand, in four consecutive observations, spaced of two weeks; in the height of the plants; in the numbers of leaves in the major stem; in the number of stems per seed piece and in the development of plrv symptoms.

Abstract: despite significant advances of the dynamic atmosphere models over the last decades of the 20th century, the empirical atmospheric models have been widely used due mostly to both its general applicability and its little dependence on the computational resources. this study is show comparison of precipitation simulation to northeast brazil (neb) - 1971-2000 from large scale dynamical modeling and regional model (downscaling) and the forecast of empirical modeling (k-nearest-neighbor (k-nn). were user the general circulation model echam4.5 together two regional models, the regional spectral model (rsm/97) from the national centers for atmospheric prediction-ncep and the regional atmospheric model system (rams) developed at colorado state university. the regional models were nested in echam4.5, forced with the observed sea surface temperature as a boundary condition, for the period from february to may. the results show that the empirical model presented a smaller absolute error than the dynamic models for the periods february to april (fma) and march to may (mam) in isolated areas of the north of maranh?o and piauí states, west and south of ceará, center-south of piauí and west and northeast of bahia state. regarding model biases, echam4.5 and the rsm/97 produced, to a large extent, a humid bias over large areas of neb, however with an average precipitation for the northern sector of neb (2os-12os and 45ow-37ow) close to the observations. rams and the analog method had a dominance of a dry bias over neb, with precipitation totals below the observed values. the model skills (using the heidke score) were evaluated for three categories dry (s), normal (n), rainy (c), showed that the analogous method has low skills, between 0,1 and 0,3 in all categories, while dynamic models presented superior skills, with larger values for categories s and c (of the order of 0,4 the 0,5), exceeding 0,6 in some areas of the northern sector of neb for category c as seen in the models echam

Abstract: soil is an essential natural resource for life. its overall capacity to function as substratum for plants, as environmental filter and regulator of gas, water and energy flow is defined as soil quality. an soil quality index can be used to monitor the effects of agricultural use on the soil attributes. the objective of this study was to determine a soil quality index (sqi) for the subsurface horizons of a cohesive argisolic yellow latosol (lax) of coastal plains under natural forest. the study area was located in the natural reserve of the atlantic forest in cruz das almas-ba, brazil. the samples were collected in a 18 x 8 m grid at a regular distance of 2 m, with 50 replications. to determine the sqi, 11 quality indicators were evaluated: macroporosity, soil density, saturated hydraulic conductivity, water retention at -33 kpa (uv33/tp), relationship of water availability in the soil (wa/tp), ph, penetration resistance, cation exchange capacity (cec), base saturation (v %), aluminum saturation (m %), and organic matter. these indicators were grouped based on three main functions: root growth in depth; water conduction and storage; and nutrient supply. the sqi value was 0.4620, which indicates a soil of poor quality for crop production. the sqi index suggests that nutrient supply, water conduction and storage must be improved for the use of this soil in agricultural systems.

Abstract: O estudo foi realizado com o objetivo de avaliar o efeito da suplementa o com fitase em dietas com diferentes níveis de fósforo disponível sobre o desempenho de frangos de corte de 22 a 42 dias. Foram utilizados 1.080 frangos Cobb-500, distribuídos em delineamento experimental inteiramente casualizado, em esquema fatorial (3 x 4) com três níveis de fósforo disponível (0,30; 0,40 e 0,50%) e quatro níveis de fitase (0; 500; 1.000 e 1.500 UF), totalizando 12 tratamentos, cada um com seis repeti es de 15 aves. As variáveis avaliadas foram: consumo de ra o, peso vivo, ganho de peso, convers o alimentar e as características de carca a. O peso vivo e ganho de peso n o foram influenciados pelos níveis de fósforo disponível e pela adi o de fitase na dieta. Houve intera o entre os níveis de fósforo disponível e os níveis de fitase para consumo de ra o e para convers o alimentar. Verificou-se melhor convers o alimentar nas aves alimentadas com dietas contendo 0,30% de fósforo disponível com 1.500 UF kg-1. Os níveis de fósforo disponível influenciaram os rendimentos da coxa e do dorso, onde o melhor resultado foi com 0,30 e 0,40%, respectivamente. Recomenda-se a utiliza o de dietas contendo 0,30% de fósforo disponível, suplementadas com 1.500 UF kg-1. The study was carried out with the objective of evaluating the effect of phytase supplements in feeds with different levels of available phosphorus on the performance of broilers from 22 to 42 days of age. We used 1080 Cobb-500 chickens distributed in a completely randomized design, in a 3 x 4 factorial scheme, with three levels of available phosphorus (0.30; 0.40 and 0.50%) and four levels of phytase (0; 500; 1,000 and 1,500 UF), totaling 12 treatments, each with six replications of 15 birds. The variables evaluated were: feed intake, live body weight, weight gain, feed conversion and carcass characteristics. Live body weight and weight gain were not influenced by the levels of available phosphorus or adding phytase to the diet. There was interaction between the levels of available phosphorus and phytase levels for feed intake and feed conversion. Better feed conversion was seen in birds fed on diets containing 0.30% available phosphorus at 1,500 UF kg-1. The available phosphorus levels affected the development of the thigh and the back, where the best results were from 0.30% and 0.40% respectively. The use of a diet containing 0.30% phosphorus, supplemented with 1500 UF kg-1 is recommended.

Abstract: the objective of this research was to apply multivariete techniques analysis to separate ecological groups. data of 37 tree species, in area without intervention, obtained in ten years of survey by the experiment of sustainable production in secondary forest of transition, established in 1986, at rio vermelho and serra azul de minas, minas gerais state, brazil were used. the species were separated in pioneers, early secondary and old secondary. the considered variables were: number of trees per hectare, number of ingrowth, mortality, basal area, volume, mean diameter, increment in diameter, increment in basal area, increment in volume, index of value of importance and natural regeneration. principal components analysis (pca); cluster analysis (ca) and the discriminant analysis (da) were used. by pca it was possible to reduce the dimension to three-dimensional with variance explanation above 79%. in the ca, seeking a classification at posteriori, it was observed that group formation did not correspond to the classification at priori. with the da, 92.86 and 57.14% of classification at posteriori and at priori respectively were correct. in conclusion: the use of the principal components analysis, cluster analysis and discriminant analysis allowed the identification of tree species that should be classified in a larger number of ecological groups; and the application of pca, ca and da in the evaluation of at priori classification confirms most researchers' subjectivity in classifying ecological groups of tree species.

Abstract: This study aimed at evaluating the performance of bullfrog tadpoles fed three levels of protein. Tadpoles were divided into 1 2 white boxes of polyethylene (62.5 x 40 x 16 cm) with a 40L capacity, which received 30L of water, receiving 30 animals, with average weight andlength of 0.027 ± 0.009g and 4.91 ± 0.45mm, respectively, resulting in a density of 1 tadpole per liter. As for feeding, commercial diets were used with three levels of crude protein (CP), 22%, 24% and 28%, with a 0.5 mm diameter, administered at a rate of 1 0% of tadpoles weight distributed once a day at noon. The experimental design was completely randomized with four replications. The best percentage of survival, 94.87%, was found in the 22% CP group. The other groups, with 24% and 28% protein, showed 81 .17% and 86.50% of survival rate, respectively. These results showed that the rations were not sufficient to provide a complete performance to the animals. Similarities regarding crude protein were observed until the 1 5th dayamong all the groups studied. However, there are some special physiological necessities, especially in relation to the protein intake, that were not well fulfilled despite the animals′good performance showed in this period.
