1. Fructan dynamics in the underground organs of Chresta exsucca (Asteraceae), a dry season flowering species
ABSTRACT Climatic seasonality has an influence on the phenology of native Cerrado plants. Herbs and subshrubs tend to flower in the rainy season, although some species of these habits flower in the dry season. Reserve carbohydrates, stored in the underground organs, are used to support phases of high energy-demand, but also may protect plants from damage dur

2. Advances in induced resistance by natural compounds: towards new options for woody crop protection
ABSTRACT: The activation of defensive responses of plants is a promising tool for controlling pests in conventional agriculture. Over the last few years, several compounds have been studied to protect crops from pests, without displaying direct toxicity for pathogenic organisms. These compounds have the ability to induce a priming state on the plants that re

3. Longevidade foliar, compostos fenolicos e nitrogenados em arvores e lianas de um fragmento de Cerrado na Estação Experimental de Itirapína, São Paulo / Leaf life span, nitrogenous and phenolic compunds in trees and lianas from a Cerrado fragment in the Itirapina experimental station in São Paulo
Trees and lianas present different strategies for allocating resources during the phonological cycle. Whereas Lianas are important floristic components and account for a significant number of rainforest species, few studies have been conducted in the Cerrado (a savanna like vegetation) biome. The duration of the leaf life span in different species reflects b

4. Invading potencial from Singapure almond (Terminalia catappa L.) in resting forest / Potencial invasor do chapéu-de-sol (Terminalia catappa L.) em área de restinga
Current and the next decade they will be identified in the time as group of the most excellent concerns with the ambient quality of the planet. Subjects as global heating and the eminent loss of the amount and quality of the water are argued constantly. A more specific ambient problem has worried specialists in the world all, including Brazil. One is about t

5. Sistemas de condução de mini melancia cultivada em ambiente protegido / Mini watermelon cultivation systems in greenhouse
Dois experimentos foram conduzidos em casa de vegetação com o objetivo de avaliar a influência do espaçamento entre plantas, do sistema de condução e da altura de poda de mini melancia conduzidas na vertical. O híbrido utilizado foi o Smile. O delineamento experimental foi em blocos casualizados, com quatro repetições. O primeiro experimento foi con

6. Manutenção de uma faixa de eucaliptos para proteção da borda de um fragmento florestal / Eucalyptus zone maintenance to protect a border of forestal fragment.
Eucalyptus zone maintenance to protect a border of forestal fragment. Nowadays, one of the biggest challenge found is the balance between the non tropical actions and the environment, this is called "sustentability". This work had as an objective values the influence of maintenance, during the forestal exploration of three lines of eucalyptus around one fore

7. Effects of subsurface drip irrigation (SDI) and plastic mulching on melon crop under protect environment / Influência do gotejamento subterrâneo e do "mulching" plástico na cultura do melão em ambiente protegido
This work aims to quantify melon yield, quantitative and qualitative aspects, as well to observe water and ions distribution (nitrate and potassium) in the root zone for two soils: Yellow Red Latossol (Sandy loam soil) and Red Argissol (Clay soil), under plastic mulching and subsurface drip irrigation (0.20 m and 0.40 m from the soil surface). Melon cycle oc

8. Estrutura e dinâmica de uma população de Caesalpinia echinata Lam. (pau-brasil) no litoral norte da Paraíba : uma perspectiva para conservação da espécie
The Pau-Brasil (Caesalpinia echinata Lam.) is a native species of Mata Atlântica, explored extensively since the discovery of Brazil. Nowadays almost disappeared, as a result of the coast forest devastation, being part of the official list of brazilian flora species threatened with extinction. This work had the objective of studying the dynamic and the stru

9. Atividade indutora de fitoalexinas e produção de substancias fungitoxicas durante a germinação de sementes de Sesbania marginata Benth
Sesbania marginata Benth is a tropical legume that stores galactomannan in its thickened endospermic cell walls. These polysaccharides are composed of a linear backbone of 13-1,4- linked D-mannose residues to which D-galactose residues are attached by a-1,6 linkages. Following germination, the galactomannan is completely broken down producing considerable am

10. Resorption Protection. Anthocyanins Facilitate Nutrient Recovery in Autumn by Shielding Leaves from Potentially Damaging Light Levels
The resorption protection hypothesis, which states that anthocyanins protect foliar nutrient resorption during senescence by shielding photosynthetic tissues from excess light, was tested using wild-type (WT) and anthocyanin-deficient mutants of three deciduous woody species, Cornus sericea, Vaccinium elliottii (Chapmn.), and Viburnum sargentii (Koehne).
