26. Reproductive ecology and diet of Cnemidophorus ocellifer Spix 1825 (Squamata: Teiidae) in a coastal area from northeastern Brazil / Ecologia reprodutiva e dieta de Cnemidophorus ocellifer Spix 1825 (Squamata: Teiidae) em Ãrea de tabuleiro no nordeste do Brasil
Chapter 1:Reproduction of Cnemidophorus ocellifer was studied based on data collected from September 2009 to August 2010 in a coastal area of the SÃo GonÃalo do Amarante municipality, CearÃ, Brazil. Lizards were captured by manual collection, with the aid of pressure rifle or tourniquet and, after dead, individuals were dissected for sex determination by

27. Effect of picloram, additives and plant growth regulators on somatic embryogenesis of Phyla nodiflora (L.) Greene
The present study describes the plant regeneration via somatic embryogenesis in suspension culture derived from the leaf and stem explants of Phyla nodiflora. The medium type, plant growth regulators, complex extract (coconut milk and malt extract) and anti-oxidant (activated charcoal, ascorbic acid, Polyvinylpyrrolidone and citric acid) markedly influenced

28. Analysis of the arabidopsis histidine kinase ATHK1 reveals a connection between vegetative osmotic stress sensing and seed maturation.
Studies using null and overexpressing mutants of the Arabidopsis water stress sensory protein ATHK1 reveal that this single protein helps to regulate abscisic acid levels both in vegetative plant tissues after osmotic stress and in maturing seeds.

29. Cell suspension culture and plant regeneration of a Brazilian plantain, cultivar Terra.
The objective of this study was to establish cell suspension culture and plant regeneration via somatic embryogenesis of a Brazilian plantain, cultivar Terra Maranhão, AAB. Immature male flowers were used as explant source for generating highly embryogenic cultures 45 days after inoculation, which were used for establishment of cell suspension culture and

30. Produção e colheita mecanizada de sementes de capim Pojuca.
ABSTRACT: In the Brazilian Central Region, flowering of Paspalum atratum cv. Pojuca is concentrated from mid February to mid March and seed maturation occurs from mid March to mid April, at the onset of the dry season. Use of combine harvesters is an excellent option Pojuca seed production areas because, besides this concentrated flowering and uniform seed m

31. Trigo BRS 264: cultivar precoce com alto rendimento de grãos indicada para o cerrado do Brasil Central.
ABSTRACT: Embrapa, through Embrapa Savanas and Embrapa Wheat have developed a new wheat cultivar, denoted BRS 264 (Triticum aestivum L), for the savana region of Central Brazil. The new cultivar is originated from the crossing Buckbuck/Chiroca/Tui. The selection from the F2 population was performed at Embrapa Savanas, at Planaltina, DF. It is indicated for i

32. Ecophysiological responses of the winegrape Chenin Blanc under different irrigation management in the São Francisco river valley.
The So Francisco Valley has been considered a new growing region for wine grapeproduction. In this region, the wines have a typical taste and are the unique ones producedunder tropical conditions. Because the irrigation management is one of the most importantfactors related to grape and wine quality, a study was carried out by the Embrapa Semirido,in the VIN

33. Caracterização bioquímica e histo-estrutural de embriões de Inga vera Willd. Subsp. affinis (DC.) T.D. Penn. durante a maturação e após secagem / Biochemical, histological and structural characterization of Inga vera Wild. Subsp. Affinis (DC.) T.D. Penn. seeds during maturation and after drying
Inga vera Pennington produz sementes com alta sensibilidade à dessecação, o que dificulta seu armazenamento. Diversos mecanismos estão relacionados tolerância à dessecação, dentre eles o acúmulo de reservas insolúveis e de moléculas protetoras, redução do metabolismo e dobramento da parede celular. Desse modo, o objetivo deste trabalho foi anali

35. Physiological, biochemical aspects and comparative proteomic during maturation, germination and seedling conversion of Ocotea catharinensis Mez. (Lauraceae). / Aspectos fisiológicos, bioquímicos e análise proteômica comparativa durante a maturação, germinação e conversão em plantas de embriões de Ocotea catharinensis Mez. (Lauraceae).
The great similarity among the events of zygotic and somatic embryogenesis allows the establishment of parameters for accompaniment of these processes. In the present work it was studied the somatic embryogenesis in Ocotea catharinensis, in the maturation and germination phases, and the zygotic embryogenesis. The biochemical parameters and differential expre
