13. Estimacao dos parametros geneticos da populacao de arroz irrigado CNA-IRAT 4/0/3.
A estimacao dos parametros geneticos de uma populacao permite obter informacoes sobre a natureza da acao dos genes envolvidos na heranca dos caracteres e estabelecer a base para a escolha dos metodos de melhoramento mais convenientes. Pretendeu-se com o presente trabalho estimar, em relacao a populacao de arroz (Oryza sativa L.) CNA-IRAT 4/0/3, os seguintes

14. Os climas do Rio Grande do Sul : variabilidade, tendências e tipologia
This thesis focuses on the analytical study of the climate in the state of Rio Grande do Sul (Brazil), addressing the variability (spatial-temporal) of climatic-meteorological elements and the approach of their trends based on the climate classification in the area. In association with this analysis is the recognition of climate variability in regional scale

15. Genetic changes in grapevine genomes after stress induced by in vitro cultivation, thermotherapy and virus infection, as revealed by AFLP
The Amplification Fragment Length Polymorphism (AFLP) technique was employed to study genetic variations which can be induced in vines by the stress occurring during different aspects of viticulture (in vitro cultivation, in vitro thermotherapy and virus infection). Analysis of AFLP banding patterns, generated by using 15 primer combinations, pointed to negl

16. Variance component estimates applying random regression models for test-day milk yield in Caracu heifers (Bos taurus Artiodactyla, Bovidae)
Random regression models (RRM) were used to estimate covariance functions for 2,155 first-lactation milk yields of native Brazilian Caracu heifers. The models included contemporary group (defined as year-month of test and paddock) fixed effects, and quadratic effect of age of cow at calving. Genetic and permanent environmental effects were fitted by a random

17. Resposta fisiológica e anatômica do açaizeiro e da palmeira real australiana ao sombreamento / Physiological and anatomical response of the assai palm and the king palm to the shading levels
The present work involves two species of producing heart of palm: assai palm (Euterpe oleracea) and the king palm (Archontophoenix alexandrae) with objective: to measure the agronomic and physiological characters, in 3 environments of luminosity, to study the anatomy of the palm and to evaluate the behavior of the two species in sight to direct the producer,

18. Morphological-reproductive characterization of jureminha (Desmanthus virgatus L. (Willd) accessions natives of Sergipe. Sergipe, São Cristóvão, SE, 2007. / CARACTERIZAÇÃO MORFOLÓGICOREPRODUTIVA DE ACESSOS DE JUREMINHA (Desmanthus virgatus (L.) Willd.) NATIVA DE SERGIPE
Among the most representative families of the world flora, the Legumonosae (Fabaceae) is one of most expressive her the capacity in fixing nitrogen in the soil and its releasing for the agroecosystems, presence in many agricultural systems, aggressive characteristic of seed dispersion, and by the considerable forage potential. The present work aimed to chara

19. Physical, physic-chemical and sensorial characteristics of the Canastra artisan Minas cheese / CaracterÃsticas fÃsicas, fÃsico-quÃmicas e sensoriais do queijo Minas artesanal da Canastra
With the necessity to get information that allow one to enrich and deepen the knowledge on the artisan cheese and its relationship with the origin region, 120 rural properties in the âCanastraâ region were visited, with the objective to get information of the involvement of the agricultural families in the production of those cheeses, dairy herd genetic pr

20. Alternatives of selection, prediction of genetic gain, estimates of correlation and coefficient of repeatability in yellow passion fruit / Alternativas de seleção, predição de ganho genético, estimativas de correlação e coeficiente de repetibilidade em maracujazeiro amarelo
The yellow passion fruit is an important tropical fruit crop in which genetic improvement needs to be increased. This work had as objective to evaluate full sib and half sib families; to evaluate the selection responses and the genetic gains by selection alternatives: selection among male parents, female/males parents (all the male parents parents), among fe

21. Genetic variability and agronomic characterization of heat tolerant Lettuce Progenies. / Variabilidade genética e caracterização agronômica de progênies de alface tolerantes ao calor.
The objective of this work was to estimate the genetic variability and the correlations between agronomic characters in thirteen progenies F7 of lettuce, and in the genitors: Verdinha, Regina and Tinto, and in the cultivars Luisa and Baba de Verão. The experiment was conducted in Vitória de Santo Antão PE, in the period from September to December of 2005.

22. CaracterizaÃÃo molecular e morfo-agronÃmica de germoplasma de aÃaizeiro / Molecular and morphoagronomical characterization of aÃai palm germplasm.
The objective of this research was to characterize the genetic and phenotypic diversities in aÃai palm (Euterpe oleracea) germplasm sampled in the Embrapa Eastern Amazon collection, through molecular markers and morphoagronomical traits. There were characterized 116 accessions from 26 origins by 28 RAPD and seven SSR primers. The 28 morphoagronomical traits

24. Populational genetic structure and sociogenetic structure of cocoon masses of Digelasinus diversipes (Kirby, 1882) (Hymenoptera: Symphyta: Argidae)
Gene variation and population genetic structure of the Neotropical sawfly Digelasinus diversipes were measured by allozyme analyses using starch gel electrophoresis. Cocoon masses were collected in Eugenia glazioviana (Myrtaceae) stems, in two areas of the "Estação Ecológica Jataí" (Luiz Antônio, SP, Brazil - 21°25' S, 47°50' W), in 2000 and 2001. The
