Abstract Application of biochar to agricultural soils is mostly used to improve soil fertility. Experimental treatments were comprised of two factors: i) drought at two level, i.e., 80% and 40% water holding capacity (WHC) which was maintained on gravimetric basis ii) three levels of biochar i.e., control, 2 t ha^-1 and 4 t ha^-1 added to soil. Experimentation was done to examine potential of biochar application to enhance the growth attributes, water relations, photosynthetic pigments and antioxidants activities in maize (Zea mays L.) seedlings. Results of study revealed that biochar application increased the growth qualities (total seedlings biomass, dry weight of… More >

Abstract In the present study, the antioxidant capacity of vitamin C was examined in the liver and the kidney tissues of mice with or without ciprofloxacin (CFX) treatment. The antioxidant capacity of the vitamin was evaluated in terms of lipid hydroperoxides (LOOH) and thiobarbituric acid reactive substances (TBARs). The experimental design was 15 days of water (control and CFX groups) or vitamin C (vitamin C and vitamin C plus CFX groups) in drinking water. One dose of CFX was injected, 15 minutes before sacrifice, in the corresponding mice.
The initial nmol of lipid hydroperoxides/g of tissue were 137 ± 11… More >

Abstract Calotropis species have been used in the traditional medicinal system for the treatment of diseases of the liver and abdomen. In view of the antioxidant and anti-hyperglycemic properties of an aqueous suspension obtained from the dried latex of Calotropis procera, the present study was carried out to evaluate its efficacy in affording protection against alloxan induced changes in rat kidney. A single intraperitoneal injection of alloxan (150 mg/kg) in rats produced hyperglycemia within 3 days and altered kidney functions over a period of 90 days. Daily oral administration of the aqueous suspension (100 and 400 mg/kg) in diabetic rats produced… More >

Abstract Plants of Azolla caroliniana were treated with different selenium concentrations (0, 1, 2, 5, 7, 10 ppm) for seven days. Selenium (Se) content in Azolla plants increased significantly with increasing Se concentrations in the culture media up to 5 ppm. This indicated that Azolla plants were a good accumulator for Se. Selenium accumulation determined changes in Azolla biomass, doubling time and relative growth rates. Treatment of Azolla plants with low concentrations of Se (1 ppm) resulted in a significant increase in biomass. This was accompanied by a reduction in hydrogen peroxide and malondialdehyde (MDA) contents; the decrease percentages were 78%… More >

Abstract The aim of the current study was to evaluate yield and phytochemical quality of tomato fruits produced using organic substrates under greenhouse conditions. The applied treatments (organic substrates) were: T1 (80% River sand + 20% Vermicompost; T2 (90% River sand + 10% Compost); T3 Steiner Solution (80% River sand + 20% Perlite); T4 (80% River sand + 5% Soil + 15% Vermicompost); T5 (85% River sand + 15% Treated manure), and T6 (80% River sand + 5% Soil + 15% Treated manure). We used a totally randomized experimental design, with four replicate treatments. Evaluated variables were: yield, relative content of… More >

Abstract During ripening, tomato fruit accumulates high levels of carotenoids. These compounds, besides their function as pigments, nutrients and antioxidants, are precursors of some important volatile compounds for the development of the characteristic aroma of these fruits. In the present work, the antioxidant capacity, lycopene and β-carotene levels, and the production of aromatic substances derived from the carotenoid biosynthetic pathway were analyzed in the tomato cultivar 7705 at different ripening stages. Results showed a significant (p<0.05) increase of lycopene and β-carotene (22.1 and 2.9 fold, respectively) from the mature green to the breaker stage. Lycopene levels increased and those of β-carotene… More >

Abstract Nanotechnology is currently an important worldwide study field because it provides control on matter at a nanometric scale. In food and agricultural fields, the applications of this technology are in early stages. Onion is one of the main vegetables grown in the world. Onion is a low calorie food which contains a large amount of flavonoids. In this work, silver nitrate application in onion was evaluated. An onion crop was developed at the University Antonio Narro in Saltillo, Mexico. Two methods of silver nitrate application were used (a nutritive solution: 0, 20, 40 and 80 mg/L of AgNO₃; and foliar… More >

Abstract Isozymes of peroxidase (POD), catalase (CAT), esterase (EST) and superoxide dismutase (SOD) were analyzed on transgenic maize (with external chitinase gene) and its parent by vertical polyacrylamide gel electrophoresis (PAGE). This study was made using shoots at the fourth leaf stage. Results showed that: POD and EST were detected in 6 bands. POD-2 and POD-3 were present at the bud and seedling stages. POD-1, POD-4, POD-5 and POD-6 were only present at the seedling stage. POD-6 expressed stronger in the transgenic maize with chitinase than in its parent. EST-2 was present only at the bud stage, and its expression in… More >

Abstract The mixed salt stress is common in nature. Salt stress always affects plant growth. Different plant species have different adaptive capacity to salty soils. Leymus chinensis is an herbaceous plant with different leaf colors. However, little research was conducted to explore the different tolerance mechanisms to salt stress among the three different leaf colour genotypes of Leymus chinensis (grey green, transitional color, yellow green). Pot experiments for Leymus chinensis in three leaf colors were conducted under mixed salt treatments in 2010. Malondialdehyde (MDA) and protein concentrations, and the activity of various antioxidant enzymes [i.e., superoxide dismutase (SOD), catalase (CAT), ascorbate… More >
