1. Pentoses Used in Cultures of Synechococcus nidulans and Spirulina paracas: Evaluation of Effects in Growth and in Content of Proteins and Carbohydrates
Abstract The biological assimilation of the sugars present in lignocellulosic residues has gained prominence since these residues are the most abundant and economic residues in nature. Thus, the objective of this work was to determine whether the use of D-xylose and L-arabinose as sources of carbon in Synechococcus nidulans and Spirulina paracas cultures af

2. Gas exchanges and growth of passion fruit seedlings under salt stress and hydrogen peroxide1
RESUMO A região semiárida do Nordeste brasileiro apresenta condições edafoclimáticas adequadas à produção do maracujazeiro, mas a água utilizada na irrigação, comumente, possui altas concentrações de sais, que são prejudiciais ao crescimento e desenvolvimento das plantas. O fornecimento prévio de peróxido de hidrogênio induz a aclimatação

3. Deficiência de macronutrientes em Cariniana estrellensis (Raddi) Kintze
Resumo O conhecimento dos efeitos da nutrição mineral sobre a fisiologia vegetal de espécies nativas é um importante auxílio para que se obtenha o sucesso desejado quando estas são usadas no reflorestamento ou na recuperação de áreas degradadas. A presente pesquisa avaliou as consequências da deficiência de macronutrientes em Cariniana estrellensi

4. Does Spraying of Atrazine on Triazine-Resistant Canola Hybrid Impair Photosynthetic Processes?
RESUMO: A canola é uma importante cultura para rotação na estação fria, e o uso de híbridos com resistência à atrazina pode contribuir para o aumento da produtividade. Este trabalho objetivou avaliar o efeito da atrazina nos processos fotoquímicos e bioquímicos da fotossíntese em canola resistente a triazinas. O experimento foi conduzido em casa d

5. Biometric and Physiological Responses to Water Restriction in Moringa oleifera Seedlings
ABSTRACT A water deficit in the soil can cause water stress in plants, triggering morphological and physiological changes. The aim of this work was evaluate the ecophysiological development of moringa seedlings under controlled water restriction. The experimental design was completely randomized at 40, 60, 80, and 100% of field capacity and six replicates.

6. Water deficit modifies the carbon isotopic composition of lipids, soluble sugars and leaves of Copaifera langsdorffii Desf. (Fabaceae)
ABSTRACT Water deficit is most frequent in forest physiognomies subjected to climate change. As a consequence, several tree species alter tissue water potential, gas exchange and production of carbon compounds to overcome damage caused by water deficiency. The working hypothesis, that a reduction in gas exchange by plants experiencing water deficit will affe

7. Potassium-modulated physiological performance of mango plants infected by Ceratocystis fimbriata
ABSTRACT Mango wilt, caused by the fungus Ceratocystis fimbriata, is an important disease affecting mango production. In view of the beneficial effects of potassium (K) in other profitable crops and the lack of information about the effect of macronutrients on mango wilt development, the present study aimed to evaluate how mango plants supplied with K respon

8. Effect of soybean ureases on seed germination and plant development
Abstract Urease catalyzes the hydrolysis of urea to ammonia and carbon dioxide. The ammonia (nitrogen (N) product of urease activity) is incorporated into organic compounds. Thus, urease is involved in N remobilization, as well as in primary N assimilation. Two urease isoforms have been described for soybean: the embryo-specific, encoded by the Eu1 gene, and

9. Diurnal Pattern of Leaf, Flower and Fruit Specific Ambient Volatiles above an Oil Palm Plantation in Pará State, Brazil
Oil palm plantations are rapidly expanding in the tropics because of insatiable global demand for fruit oil to be used in food, biofuels and cosmetics. Here we show that three tissue-specific volatiles can be quantified in ambient air above an African-American hybrid oil palm plantation in Brazil and linked photosynthesis (isoprene), floral scent (estragole)

10. Carbon primary sources and estuarine habitat use by two congeneric ariid catfishes in a subtropical coastal lagoon
ABSTRACT Although ariid catfishe species are known to use coastal systems during some stages of their life cycles, the energetic contribution of estuarine resources and habitat use by many species in this family are still unclear. We used stable isotope analyses to estimate the assimilation of primary carbon sources and to infer the use of estuarine and fres

11. Combined effects of low light and water stress on Jatropha curcas L. promotes shoot growth and morphological adjustment
Jatropha curcas (physic nut) is a plant with economic and pharmaceutical uses. Basic studies on the influence of environmental factors on the early development of J. curcas are important for improving farming techniques and increasing productivity. This study investigated the adjustments of J. curcas to the environmental factors of drought and light stress i

12. Magnesium-induced alterations in the photosynthetic performance and resistance of rice plants infected with Bipolaris oryzae
Brown spot (BS), caused by the fungus Bipolaris oryzae, is one of the most important diseases contracted by rice. We investigated the effect of magnesium (Mg) on the development of BS, caused by Bipolaris oryzae, and the effects of disease development on the photosynthetic performance of rice (Oryza sativa L.) plants (cv. Metica-1) grown in nutrient solution
