1. Foliar application of molybdenum on cover crops and response of common beans in successive cultivation
ABSTRACT The effects of foliar application of Mo and use of N from cover crops (Crotalaria juncea L. and Canavalia ensiformis (L.) DC) on the performance of common beans were investigated in this study. Field experiments were carried out in a succession planting system (cover crops - common beans), and nitrate reductase activities were evaluated in the labor

2. Application methods of Azospirillum brasilense in first- and second-crop corn
RESUMO Objetivou-se verificar se a inoculação de Azospirillum brasilense via semente ou sulco de semeadura pode reduzir a necessidade de adubação nitrogenada no milho, em primeira e segunda safra. Os experimentos foram conduzidos, no município de Chapadão do Sul, MS, em primeira safra (2014/2015) e segunda safra (2016). Na primeira safra utilizou-se o

3. Nitrate Reductase Activity and Nitrogen and Biomass Accumulation in Sugarcane under Molybdenum and Nitrogen Fertilization
ABSTRACT Prior research on sugarcane showed increment of productivity following molybdenum (Mo) fertilization and some indication of the potential role either on nitrate reductase activity (NRA). However, this increment can depend on sugarcane variety and nitrogen (N) fertilization. This study aimed to evaluate the effect of Mo fertilization on Mo uptake, on

4. Nitrogen source influences the antioxidative system of soybean plants under hypoxia and re-oxygenation
ABSTRACT: In this work, we compared nitrate-supplied plants (non-nodulated) with non-nitrate-supplied plants (nodulated) under oxygen privation of root system (hypoxia) and re-oxygenation (post-hypoxia; recovery) in order to verify whether N sources affect the antioxidant system during oxidative stress caused by hypoxia and post-hypoxia conditions. Antioxida

6. Fast detection of Mycobacterium tuberculosis in culture-positive sputum samples by nitrate reductase activity
ABSTRACT Microscopy and bacterial culture are the main tools in the diagnosis of tuberculosis. Since the slow growth of Mycobacterium tuberculosis impairs rapid diagnosis strategies, especially in countries where the latter are the only available resources, the ongoing development of new and inexpensive tools based on mycobacterial metabolism optimizing grow

7. 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

8. Foliar application of 28-homobrassinolide mitigates salinity stress by increasing the efficiency of photosynthesis in Brassica juncea
Prior to sowing, seeds of Brassica juncea Czern and Coss cv. Varuna were soaked in water (controls) or in 50, 100 or 150 mM of sodium chloride (NaCl) for 6 h. The resulting plants, at 15, 30 and 45 days after sowing (DAS) were either not treated (controls) or were treated with aqueous solutions of the hormone 28-homobrassinolide (HBL), which was applied to t

9. Produtividade e características fisiológicas do consórcio milho-braquiária / Productivity and physiological characteristics of Corn-Brachiaria Intercrop
Three experiments were installed between the years of 2007 and 2009, two of them made in the field and one held in a greenhouse. Our aims were: experiment 1 - evaluate the effects of emergence time in brachiaria and in the application of atrazine herbicide mixture + nicosulfuron at two levels of fertilization, in photosynthesis, stomatal conductance, transpi

10. 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

11. Establishment of sensitive and resistant variety of tomato on the basis of photosynthesis and antioxidative enzymes in the presence of cobalt applied as shotgun approach
Cobalt (Co) affords both beneficial as well as toxic effects to plants. The present study was performed with an aim to find out the varietal differences among five tomato cultivars against the Co induced changes in growth, photosynthesis, nitrate reductase (E.C.1.6.6.1), carbonic anhydrase (E.C.4.2.1.1), antioxidative enzymes i.e. peroxidase (E.C.1.11.1.7),

12. Synergistic response of auxin and ethylene on physiology of Jatropha curcas L.
Jatropha curcas L. is a versatile crop since all its plant material is brought to use either as energy source, industrial or medicinal purpose. Several studies are ongoing in different parts of the world to optimize, enhance and exploit the growth, fruiting cycle and different developmental stages of the plant so that the economic yield of the plants can be
