Fires are complex processes having important impacts on biosphere/atmosphere interactions. The spatial and temporal pattern of fire activity is determined by feedbacks between climate plant functioning through biomass desiccation, usually estimated danger indices (FDI) in official risk prevention services. Contrasted vegetation types from fire-prone Brazilian biomes may respond differently to soil water deficit during the season. Then, we propose evaluate burned area (BA)/FDI relationship...
Cupania vernalis Camb. (Sapindaceae) é uma espécie freqüente em quase todas as formações florestais, principalmente Cerrado e Mata de Galeria, abrangendo os Estados Minas Gerais, Mato Grosso São Paulo até o Rio Grande do Sul. Essa se destaca, principalmente, pelo seu emprego plantios mistos destinados à recuperação áreas degradadas preservação permanente, fato seus frutos serem muito apreciados consumidos por pássaros e, ainda, na medicina popular contra asma tosses convulsivas. O estudo da...
Events by changes in climate alter the growth and physiology of sugarcane. In this context, study aimed to investigate morphological, anatomical, physiological responses two different sugarcane varieties under a condition high carbon dioxide (CO2) associated with water deficit, testing hypothesis that drought are modulated plant scales. Thirty days after sprouting, plants were grown atmosphere (400 680 μmol CO2 mol−1 air) restriction conditions. At morphological level, we assessed total...
The peach tree (Prunus persica) is a fruit species native to temperate climates that requires chill during its hibernal period overcome dormancy. However, due genetic breeding, varieties are currently grown in subtropical and tropical regions where there low occurrences of this phenological stage. This study evaluated the adaptability stability reproductive vegetative phases cultivars climate. An experiment was designed randomized blocks with split time plots, 23 four replications, each...
This study aimed to establish a strategy for drought-tolerant selection in Arabica coffee genotypes Brazil, combining field trials under natural conditions with controlled growth condition experiments. A group of was evaluated the greenhouse using 28 morphological, anatomical, and physiological traits. In addition, productivity field. Under water deficit greenhouse, 13 studied traits showed significant genetic variance. For these traits, heritability coefficients estimated based on progeny...
Diferenças na disponibilidade de radiação podem causar modificações estrutura e função das folhas do cafeeiro, que responder maneira diferencial à por alterações morfológicas, anatômicas, crescimento taxa fotossintética. O objetivo deste trabalho foi avaliar características morfofisiológicas cafeeiros (Coffea arabica L. cv. "Oeiras") sombreados acácia (Acacia mangium Willd.) época seca chuvosa no sul Minas Gerais. As maiores taxas fotossintéticas espessuras da epiderme adaxial foram...
Abstract The phenotype of an individual emerges from the interaction its genotype with environment in which it is located. Phenotypic plasticity (PP) ability a specific to present multiple phenotypes response environment. Past and current methods for quantification PP limitations, mainly what constitutes systemic analysis traits. This research proposes integrative index quantifying evaluating PP. multivariate (MVPi) was calculated based on Euclidian distance between scores canonical variate...
Abstract Stable isotopic determination constitutes a useful tool to identify the processes that control dynamics of carbon and nitrogen flow in plants, unravelling mechanisms their differential investment under different environments. This work aimed evaluate spatiotemporal variation source‐sink patterns coffee trees field conditions response climatic through assessment stable isotopes. For this purpose, stems, leaves, fruit samples from were collected following temporal pattern based on...
The global changes are marked by alteration on the normal patterns of important biochemical and biophysical processes Earth. However, real effects as well feedbacks over vegetation still unclear. Part this uncertainty can be attributed to inattention stakeholders scientists towards its complex interrelations with environment, which drive plant physiological in different space-time scales. Notwithstanding, some key subjects could better elucidated a more ecology approach. We discuss issues...
Abstract The use of growth rings dimensional parameters has been an important tool for the understanding growth, biomass allocation and climatic characterisation forest species. However, its potential is unknown in perennial crops socio‐economic importance, such as coffee. This work aimed to understand how analysis can be used a proxy determinants vegetative different organs coffee trees. was carried out southern region Minas Gerais, Brazil. structure cross sections orthotropic stem trees (...
Interest in Australian cedar (Toona ciliata M. Roemer var. australis) has increased due to its economic potential as an alternative the use of native hardwood, and because resistance Hypsipyla grandella moth, which affects cedars. The growth regulators such paclobutrazol (PBZ) planting T. is aimed mostly at obtaining seedlings with greater H. a desirable height for handling. However, this regulator tends induce modifications both leaf anatomy photosynthetic potential. present study evaluate...
Abstract Cerrado soils are acidic and nutrient-poor, with high content of solubilized Al 3+ . Plants growing in these conditions may display adaptations to cope aluminum concentrations especially during early developmental stages. We investigated leaf nutritional status, photosynthetic growth characteristics the initial establishment Handroanthus impetiginosus (Mart. Ex Dc.) Mattos, a secondary tree species distributed Brazilian Cerrado. Our goal was understand leaf-level traits related...
Differences in the availability of solar radiation can cause modifications structure and function coffee plant leaves, such as physiological, growth disease incidence alterations. The objective this work was to evaluate physiological characteristics development developing plants submitted five shading levels (0, 35, 50, 65 90% shading) dry rainy period. evaluations were conducted Coffea arabica L. species, cultivar Catucaí Amarelo 2SL. treatments disposed a randomized block design with plots...
Os metodos de estimativa do indice area foliar (IAF) utilizados para cafeeiros (Coffea arabica L.) apresentamlimitacoes relacionadas a representacao particularidades da cultura que afetam o IAF no tempo e espaco. Desenvolveuseeste trabalho objetivando propor um metodo forma reduzir essas limitacoes. Foram utilizadoscafeeiros em fase produtiva, cultivos regiao Lavras-MG, das variedades Mundo Novo Catuai, coletados durantea estacao seca chuvosa 2010 2011. Nessas plantas avaliou-se altura...

Para isso, foi conduzido um experimento em estufas cobertas com filme plástico 150µm três subcobertura: tela termorrefletora, preta, vermelha e ambiente controle sem uso tela. a modificação ambiental ocasionada pelos tratamentos, foram instalados cada estufa externo termohigrômetro data logger, que registrou temperatura 15 minutos do dia 18/05/2011...
Objetivou-se com o presente trabalho avaliar efeito do acido silicico em caracteristicas fisiologicas e anatomicas de mudas de cafeeiro (Coffea arabica L.) inoculadas Cercospora coffeicola Berk. & Cook. Os tratamentos consistiram seis doses de no solo (0, 0,5; 1; 2; 4 6 g kg 1 ), delineamento experimental blocos casualizados, quatro repeticoes.

O uso de sistemas cultivo agrícola que favorecem a conservação dos recursos naturais e diversidade produção representa uma alternativa para produtores visam menores custos em sustentável. Dentre esses cultivo, destaca-se o sistema consórcio entre cafeeiros seringueiras, tem sido estudado na região sul Minas Gerais. Nesse contexto, avaliaram-se características trocas gasosas, fluorescência da clorofila relações hídricas monocultivo consórcio, fase implantação cultivos, com objetivo verificar...
RESUMO Cercosporiose é uma das principais doenças que comprometem o crescimento de mudas café por causar desfolha e redução no crescimento. A doença apresenta maior severidade quando cafeeiro está submetido ao déficit hídrico. O uso irrigação alternativa para minimizar os danos causados pela doença. Objetivou-se neste trabalho avaliar impacto da na fisiologia do em função lâmina irrigação. As plantas foram submetidas a três lâminas (0.1, 0.6 1.2 mm.dia-1); inoculadas não com C. coffeicola,...
