the management of postprandial hyperglycemia is an important strategy in the control of diabetes mellitus and complications associated with the disease, especially in the diabetes type 2. therefore, inhibitors of carbohydrate hydrolyzing enzymes can be useful in the treatment of diabetes and medicinal plants can offer an attractive strategy for the purpose. vaccinium arctostaphylos leaves are c...

cots in the family Commeliaceae. The basic morphology of these plants appears to favor root-knot nematode development in aboveground plant parts. Leaves of both plants develop in the crown near the soil; they are large, 20-30 cm long, and densely arranged so that nematodes on younger leaves are protected from direct solar irradiation. The dense pubescent foliage, especially the convoluted young...

the sugarcane whitefly, n. andropogonis, sucks severely the sap of plant and produces a lot of honey-dew. this study was conducted to quantify the relationships between whitefly damage and sugar quality in order to estimate the monetary loss occurring at different levels of damage at harvest time. during this trial, the number of infected leaves was expressed as an index. the investigation was ...

The effects of lead on the proline content and dry weight of leaves and roots were investigated in two canola cultivars (Brassica napus L.) grown in the Hoagland solution. The growth of treated plants was inhibited under lead stress. Lead induced differential accumulation of proline in canola grown in solution with the addition of 0, 100 and 200 mgL-1 of Pb. Hyola308 cultivar showed low biomass...

In this study, the branch, leaves, flowers, roots and mixed all parts of different nine Euphorbia species were analyzed for their trace element contents by using ICP-MS. The samples were digested by concentrated nitric acid and hydrogen peroxide in a microwave by ICP-MS before the analysis. The accuracy and precision of the method was evaluated by CRM 1573a Tomato Leaves. Trace element contents...

the main reasons for the fixation of some elements and consequently nutrient deficiencies, especially phosphorus, iron and zinc, are high levels of calcium (calcareous soils) and soil ph. two sulfur fertilizers (sulfur alone and sulfur + organic material + thiobacillus spp.) with two rates (2 and 4 kg sulfur/tree) were used to decrease soil ph and availability of p, fe and zn in apple trees dur...

Effects of plant litter type (larch needle-leaves, mixed broad-leaves, and sasa green leaves) and nutrient addition (nitrogen and phosphorus) on bacterial community-level physiological profiles (CLPPs) of a forest soil were examined using BIOLOG EcoPlates(TM). Both the litter and nutrient additions significantly increased color development in most of the wells in the BIOLOG microplates, with th...
