1. The relationship between plant density and survival to water stress in seedlings of a legume tree
ABSTRACT Competition for soil water is one of the major processes that drive the assembly of plant communities, particularly in regions subjected to long dry seasons. The relationship between plant density and soil water competition has strong, but poorly understood, practical implications for population dynamics, restoration and conservation. We planted see

2. ESTIMATIVA DE BIOMASSA AÉREA E TEOR DE CARBONO DA ESPÉCIE RHIZOPHORA MANGLE L. / ABOVE-GROUND BIOMASS ESTIMATION AND CARBON STOCK IN RHIZOPHORA MANGLE L.
The interest in quantifying mangrove forest biomass has increased in recent years due to the potential that tropical forests have in accumulating atmospheric carbon. The high organic carbon in mangrove attributes an important role in the estimation of global carbon and the processes of climate change mitigation. The objective of this study was to develop all

3. Padrão de germinação de sementes e estabelecimento de mudas de guanandi (Calophyllum brasiliense Cambess.)
CHAPTER II: Calophyllum brasiliense Cambess. is a tree, typical of tropical rainforests, with seed germination variable and uneven due to restrictions of the layers of the integument. The objective was to characterize the dormancy of seeds of species by their ability to soak, germination, emergence, distribution of germination over time and the timing and qu

5. Respostas do trigo aos estresses causados por baixa luminosidade e/ou excesso de agua no solo.
O experimento foi conduzido, em 1987, em casa de vegetacao da Faculdade de Agronomia da Universidade Federal do Rio Grande do Sul, em Porto Alegre, RS. O objetivo do trabalho foi avaliar o efeito dos estresses causados por excesso de agua no solo e pela reducao de luminosidade sobre 12 genotipos de trigo (Triticum aestivum L.). Foram observadas signficativas

7. Suprimento de nitrogênio e de potássio e características morfogênicas, nutricionais e produtivas do capim-Marandu / Nitrogen and potassium supply and the morphogenetic, nutritional and productive characteristics of Marandu palisadegrass
Nitrogen and potassium are essentials for plant development, are extracted by plants in high amounts and their availabilities may change the morphogenetic, productive and nutritional characteristics of plants. The objectives of this research were: a) to assess fertilization with nitrogen and potassium rates on morphogenetic and shoot and root dry matter prod

8. Tamanho de parcelas para quantificação de biomassa e carbono em uma floresta ombrófila densa na Mata Atlântica / Size of fragments for the quantification of biomass and carbon in a thick ombrophilous rainforest in Mata Atlântica
Rainforest is defined as a vegetable formation which takes up a large part of the Brazilian territory, from the Amazon Rainforest to the forests of the highlands of the southern states of Brazil, going through the Atlantic Forest. Due to the type of colonization Brazil had , which was a colonization of exploitation, a large part of this forest was destroyed,

9. Technical parameters for the white mold control using air- assisted hydraulic sprayer / Parâmetros técnicos para o controle do mofo-branco na cultura do feijão utilizando pulverizador hidráulico de barra com assistência de ar
The white mold, caused by the fungus Sclerotinia sclerotiorum, is one of the most destructive diseases of the bean plant in the world, especially in crops under conditions of mild temperatures and high soil and air humidity. In general, primary infections caused by this fungus start due to the presence of free water and an exogenous energy source, usually se

10. Adubação nitrogenada com uréia e adubos verdes na cultura do arroz e efeito residual no feijoeiro / Nitrogen fertilization with urea and green manures in rice crops and its residual effect in bean crop
The association of green manures and mineral N sources is becoming a promising option for nitrogen fertilizer management, with the objective of recovering the soil fertility, increase of soil organic matter, reduce the loss of mineral N from the readily available sources, and in the case of legume incorporate biologically fixed N to the soil. The objectives

12. Ecologia do bicudo-do-algodoeiro Anthonomus grandis Boheman, 1843 (Coleoptera:Curculionidae) no Cerrado do Brasil Central
The boll weevil Anthonomus grandis Boheman, 1843 (Coleoptera: Curculionidae), one of the main pests of cotton, was introduced in Brazil in 1983. It causes the most serious damage to the crop, such as the falling of the flower buds, destruction of bolls and reduced linter production. The serious pest status of the boll weevil is mainly due to its high reprodu
