Shade and drought commonly occur together in turfgrass systems due to competition with trees for light soil water. Two greenhouse studies were conducted evaluate the effects of combined shade stress on bermudagrass [Cynodon dactylon (L.) Pers.] hybrid [C. Pers. × C. transvaalensis Burtt Davy] physiology. ‘Latitude 36 Turf Bermudagrass’ (Latitude 36TM) ‘Riley's Super Sport’ (Celebration®) select...
the effect of seed inoculation by phosphate solubilizing microorganisms on growth, yield and nutrient uptake of maize (zea mays l. sc. 704) was studied in a field experiment. this experiment was conducted in meshkin abad experimental station during 2005. the experiment design consisted of four randomized complete blocks in a split-factorial arrangement. the main-plots regarding simulating water...
Ministers are set to scrap plans for minimum nursing home staffing ratios as part of a move to water down proposals for national care home standards.
Profitability assessment has prime importance for every crop husbandry practice and cultural operation. For this purpose, two field experiment was carried out to investigate the response of spring planted sunflower hybrids to different irrigation levels/schedules and foliar application of abscisic acid. Two studies were done at the Agronomic Research Farm, University of Agriculture, Faisalabad,...
In the present study three cDNA fragments were cloned using degenerate primers for Mn-sod genes and PCR: two showed a high degree of identity with Mn-sods from plants and the third with Fe-sod. Arbuscular mycorrhizal (AM) symbiosis down-regulated their expression pattern under well-watered conditions. In contrast, AM symbiosis in combination with drought stress considerably increased the expres...
Photosynthesis is fundamental to biomass production, but sensitive to drought. To understand the genetics of leaf photosynthesis, especially under drought, upland rice cv. Haogelao, lowland rice cv. Shennong265, and 94 of their introgression lines (ILs) were studied at flowering and grain filling under drought and well-watered field conditions. Gas exchange and chlorophyll fluorescence measurem...
Net photosynthesis is stimulated in third seedling leaves of barley plants whose lower two leaves are heavily infected by Erysiphe graminis f.sp. hordei Marchal. Stimulation is greater in water-stressed than in well-watered plants. In stressed, but not in well-watered plants, stimulation is associated with the maintenance of high leaf water potential and high leaf conductance. A small part of t...
BACKGROUND: Researches in the field of engine oils sludging take its origin from 1955. Scientists different countries were searching for reasons, defining consequences, building a chain cause-effect links. Researchers have found that sludge represents complex compounds with low aggregative stability, such as: additives inserted into basis during production, partially oxidised fuel fractions sub...
