13. Desempenho de populações segregantes de algodoeiro obtidas por três métodos de hibridação
CHAPTER I - The objectives of this research were to make predictions on segregant populations performance on upland cotton as for selection, using the method proposed by Jinks and Pooni (1976), as well as to identify amongst three different crossing methods, which will originate the most promising population for selection purposes. The present work was condu

15. Análise de crescimento e produtividade de duas variedades de cana-de-açúcar (Saccharum spp) influenciadas por doses de fósforo
The knowledge of the leaf area is required every time the sugarcane is subjected to evaluation in which different varieties are compared or submitted to different environmental conditions, managements or fertilizations, therefore evidently showing alteration in dimensions of the plant leaves, so affecting the photosynthetic process. Although the higher breat

16. Morphophysiological characteristics and herbage accumulation in mombaça grass subjected to defoliation regimes / Características morfofisiológicas e acúmulo de forragem em capim-mombaça submetido a regimes de desfolhação
Grazing systems that take into account the rhythm of regrowth of forage plants after defoliations can optimise herbage accumulation and ensure the control of sward structure. In these context, the objective was to evaluate patterns of response of Panicum maximum cv. Mombaça to defoliation in two experiments using measurements of sward morphogenetic and stru

17. Genetic analysis of resistance to anthracnose leaf blight in maize. / Análise genética da resistência à antracnose foliar em milho.
The objectives of this work were to study the inheritance of resistance to anthracnose leaf blight, estimate the genetic parameters, and identify molecular markers associated with resistance genes to this disease. Genetic parameters were estimated based on the analysis of mixed inheritance models in six generations of four crosses between two resistant (DAS4

18. Produção de forragem de capins do gênero Panicum e modelagem de respostas produtivas e morfofisiológicas em função de variáveis climáticas. / Forage yield of Panicum grasses and modeling yield, morphological and physiological traits in response to climatic variables.
The brazilian livestock industry is based on the use of tropical pastures with high production potential which benefits from favorable environmental conditions over the year. However, the seasonal pattern of climatic conditions, mainly temperature and daylength, concentrates most of the annual forage accumulation during the spring and summer. Thus, knowing t

19. NÃmero de clones por famÃlia, seleÃÃo clonal e seleÃÃo de famÃlias em programas de melhoramento de batata / Number of clones per family and clonal versus family selection in potato breeding programs.
Potato (Solanum tuberosum L.) breeding programs have the objective of producing superior clones from biparental crosses among many different cultivars. Aiming to get these superior clones breeders evaluate great numbers of clones without giving any attention to the families they came from. Simmonds (1996) suggested that breeders can choose between select clo

20. Voltage-dependent gating mechanism for single fast chloride channels from rat skeletal muscle.
1. A voltage-dependent gating mechanism for the fast Cl- channel was developed from the analysis of single-channel current records obtained with the patch clamp technique from primary cultures of rat skeletal muscle. Up to 10(6) open and shut intervals were analysed from each of five different excised patches of membrane containing a single fast Cl- channel.

21. Spreadsheet Method for Evaluation of Biochemical Reaction Rate Coefficients and Their Uncertainties by Weighted Nonlinear Least-Squares Analysis of the Integrated Monod Equation
A convenient method for evaluation of biochemical reaction rate coefficients and their uncertainties is described. The motivation for developing this method was the complexity of existing statistical methods for analysis of biochemical rate equations, as well as the shortcomings of linear approaches, such as Lineweaver-Burk plots. The nonlinear least-squares

22. Cytoplasmic calcium buffers in intact human red cells.
1. Precise knowledge of the cytoplasmic Ca2+ buffering behaviour in intact human red cells is essential for the characterization of their [Ca2+]i-dependent functions. This was investigated by using a refined method and experimental protocols which allowed continuity in the estimates of [Ca2+]i, from nanomolar to millimolar concentrations, in the presence and
