1. Physiological and toxic effects of selenium on seed germination of cowpea seedlings
ABSTRACT Selenium (Se) is considered a beneficial chemical element for plants, but in high concentrations it may present symptoms of toxicity. The present study aimed to evaluate 11 concentrations of Se (0; 0.1; 0.5; 1; 5; 10; 20; 40; 80; 400; 800 mg.L-1) to determine the low and high (toxicity) critical levels to seed germination of cowpea (Vigna unguiculat

2. The effects of magnesium deficiency on sugar partitioning do not restrict the root growth in Eucalyptus young plants
Resumo Os sintomas da deficiência de magnésio (Mg) têm sido bem documentados em plantas cultivadas. A relação entre a deficiência de Mg, como um importante fator de estresse abiótico, e a partição do açúcares, pode restringir o crescimento das raízes e limitar o sucesso do plantio no campo. Apesar disso, os efeitos fisiológicos primários da bai

3. Effect of Nutrient Sources on the Alginate Accumulation in the Culture Liquid of Azotobacter vinelandii D-05 and Obtaining Biocomposite Materials
ABSTRACT Using the classic biotechnological methods, the dependence of A. vinelandii D-05 culture alginate production from the media carbon and nitrogen content was investigated. The maximal alginate production was observed during cultivation bacterium in the medium with 2 to 4% of sucrose, but the maximal growth was found in the medium with 4% glucose. It w

4. Sugars levels of four sugarcane genotypes in different stem portions during the maturation phase
ABSTRACT Maturation is a characteristic of sugarcane plant (Saccharum spp.) and even when grown under the same soil and climate conditions the varieties differ on the maturation curve. Thus, studies that allow establishing maturation curves of different sugarcane genotypes in the local soil and climate may indicate the proper harvesting period to ensure bett

5. The physiological and biochemical mechanism of nitrate-nitrogen removal by water hyacinth from agriculture eutrophic wastewater
ABSTRACT Large amount of agriculturl wastewater containing high level nitrate-nitrogen (NO3 --N) is produced from modern intensive agricultural production management due to the excessive use of chemical fertilizers and livestock scale farming. The hydroponic experiment of water hyacinth was conducted for analyzing the content of NO3 --N, soluble sugar conten

6. Endophytic bacteria affect sugarcane physiology without changing plant growth
ABSTRACT The aim of this study was to evaluate if endophytic bacteria inoculants would be beneficial to the sugarcane varieties IACSP94-2094 and IACSP95-5000, promoting changes in photosynthesis and plant growth. The plants, obtained from mini stalks with one bud, were treated with two bacteria mixtures (inoculum I or II) or did not receive any inoculum (con

7. The effect of fluoride toothpaste on root dentine demineralization progression: a pilot study
The anticaries effect of fluoride (F) toothpaste containing 1100 µg F/g in reducing enamel demineralization is well established, but its effect on dentine has not been extensively studied. Furthermore, it has been shown that toothpaste containing a high F concentration is necessary to remineralize root dentine lesions, suggesting that a 1100 µg F/g concent

8. Process-based simple model for simulating sugarcane growth and production
Dynamic simulation models can increase research efficiency and improve risk management of agriculture. Crop models are still little used for sugarcane (Saccharum spp.) because the lack of understanding of their capabilities and limitations, lack of experience in calibrating them, difficulties in evaluating and using models, and a general lack of model credib

9. Effect of cariogenic challenge on the stability of dentin bonds
Objective: The oral environment is subject to biofilm accumulation and cariogenic challenge, and few studies exist on the effect of these factors on the bond strength of adhesive systems. The aim of this study was to test if the exposure of adhesive interfaces to cariogenic challenge under biofilm accumulation could promote higher degradation than the expos

10. Climatic effects on sugarcane ripening under the influence of cultivars and crop age
The lack of information about the effects of cultivars, crop age and climate on the sugarcane (Saccharum ssp.) crop yield and quality has been the primary factor impacting the sugar-ethanol sector in Brazil. One of the processes about which we do not have a satisfactory understanding is sugarcane ripening and the effects of cultivars, crop age and climate on

11. Análise do transcritôma e proteôma do colmo de cana-de-açúcar relacionada ao metabolismo da sacarose / Transcriptomic and proteomic analysis of sugarcane culm relationaded to sucrose metabolism
Sugarcane is a important crop in the Brazilian economy for both, sugar and green biofuel production, accounting for more than US$ 20 billions/year, placing Brazil as the most important country in this trade. On the other hand sugarcane has reached a limit in sucrose production, an effect of the narrow gene pool used in current commercial breeding programs. O

12. Sucrose metabolism during fruit development in coffea racemosa.
Sucrose is one of the compounds in the raw coffee bean that has been identified as an important precursor of coffee flavour and aroma. In order to increase our knowledge of sucrose metabolism in coffee species, sucrose and reducing sugar content were investigated in the fast fruit-ripening coffee species Coffea racemosa. Fruits were harvested regularly from
