1. Advances in the knowledge of the natural history of aquatic plants in the Neotropics
ABSTRACT Until the mid-XX century, little awareness on the ecological services or socio-environmental problems and benefits related to aquatic plants culminated in bottlenecks on their natural history, especially for the Neotropics. In this context, Acta Botanica Brasilica (ABB) organized this special issue to promote the advancement of knowledge on this eco

2. Nitrate reductase activity in field-grown pueraria lobata (Kudzu) in southeastern Brazil.
Although Pueraria lobata (Willd.) Ohwi (P. thunbergiana) (Sieb. & Zucc.) Benth.) is thus ecologically and economically important in much to world, its physiological ecology and other factor contributing to its invasive growth are not well understood. Nitrate reductase activity (NRA) measurements have long been used to indicate the effect of changes in the en

3. Lianas of Seasonally Dry Forest: Ecophysiology and Use in Restoration Ecology / Lianas da floresta estacional semidecidual: ecofisiologia e uso em restauração ecológica
Lianas are important components of the structure and dynamics in seasonally dry forests, but there are few studies on their ecophysiology and use in restoration ecology. The objective of this study was to evaluate the ecophysiology of seeds and juveniles of species of liana in the preferences for environmental regeneration and the variables involved in using

4. Avaliação ecofisiológica de subamostras de alho cv. Amarante / Ecophysiological evaluation of cv. Amarante garlic subsamples.
Garlic cultivars present different yield potentialities, expressed by the plant s morphological and physiological characteristics, according to the environment and cultural management. Thus, twenty sub-samples of garlic cv. Amarante belonging to the Germplasm Bank of the Universidade Federal de Viçosa (BGH/UFV) were evaluated for their morphological and phy

5. Atributos funcionais e a distribuição de especies do cerradão e da floresta estacional semidecidual / Functional traits and the distribution of cerradão and seasonally dry forest species
Cerradão e floresta estacional semidecidual (FES) são consideravelmente distintos em relação à estrutura, à composição florística e ao funcionamento, com poucas espécies comuns às duas áreas. Entretanto, ainda não há consenso sobre os fatores que efetivamente controlam a dinâmica dessas formações. O objetivo deste estudo foi investigar a inf

6. Caracterização da capacidade fotossintética e da condutância estomática em sete clones comerciais de Eucalyptus e seus padrões de resposta ao déficit de pressão de vapor / Photosynthetic capacity and stomatal conductance characterization for seven commercial Eucalyptus clones and their variation due to vapor pressure deficit
This study aimed to characterize the physiological variables related to photosynthesis, in seven commercial Eucalyptus clones with high productivity, by evaluating maximum photosynthetic capacity (Amax), and the response of photosynthesis (A), stomatal conductance (gs) and transpiration (E) to Vapor Pressure Deficit (VPD). A trial was installed in 2004, at E

9. Culture environment in the micropropagation of Annona glabra L. / "Ambiente de cultivo na micropropagaÃÃo de Annona glabra L."
The Annona glabra L. has aroused a great interest in Brazil in recent years, since it is a species with the capacity to adapt to several environments and it belongs to the fruit group which has medicinal properties of substances isolated from leaves, fruit and seeds. The initiatives to explore the potential of this species are incipient still, especially due

10. Germinação, emergência da plântula, produtividade e qualidade da fibra de Gossypium hirsutum L. CV. DP 660 sob ação de bioestimulante / Germination, seedling emergence, productivity and fiber quality of Gossypium hirsutum L. cv. DP 660 under action of biostimulants
Cotton is the most important vegetable fiber for man who uses it as a raw material in the production of tissues which has intrinsic qualities unequaled to in other fibers. For this reason, the viability of the seed has been receiving special attention, since its quality is demonstrated in the subsequent cultures, in terms of uniformity, greater performance o

11. Efeito de práticas silviculturais sobre a produtividade primária líquida de madeira, o índice de área foliar e a eficiência do uso da luz em plantios de restauração da Mata Atlântica / Effects of silvicultural practices on wood net primary production, leaf area index and light use efficiency of Atlantic Forest restorations
The purpose of this study was to indentify the most appropriated restoration model by manipulating floristic composition and silvicultural practices, and to understand how the best development was explained by the factors that controls light use and light use efficiency at the canopy. A "Restoration models for Atlantic Forest disturbed lands aiming carbon se

12. Ecophysiological attributes of hybrid DKB-390 and sthocastic model for predicting grain productivity / Atributos ecofisiológicos do híbrido DKB-390 e modelo estocástico para previsão da produtividade de grãos
Maize is on of the world most important crops, given that the products generated from this cereal are largely used by sectors like starch industry, animal and human nutrition, as well as biomass energy production and refineries. For these reasons, there is frequently a huge interest in knowing the potential adoption of the main available genotypes in relatio
