gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
Variations in camptothecin (CPT) content in relation to leaf characteristics namely leaf area, leaf biomass, and specific leaf area (leaf area divided by leaf biomass), and the influence of climatic factors on CPT content in saplings of Camptotheca acuminata Decne. were studied. Leaf area and CPT content showed a logarithmic relationship in young leaves similar to that between leaf biomass and ...
Study of heritability and gene action to improve agronomic and physiological traits, especially under drought stress conditions, are very important. The objectives of this study were to investigate heritability for important agronomic traits and some physiological characters in a cross between two spring wheat cultivars. The experiment was carried out using different generations (BC1, BC2, F3, ...
In order to investigat e of Tobacco germplasm genetic diversity, 49 genotypes were grown in Tobacco Research Institute (Rasht, IRAN) as a simple lattice design 7×7 with 2 replications and 12 treatments were evaluated as well. Correlation analysis to studied traits showed that Fresh leaf yield with leaf number, leaf length, leaf width, leaf area index, plant height, flowering period and days...
1. Populations of Metrosideros polymorpha establish across a broad range of precipitation in Hawai‘i – from <400 to >10000 mm per year. To determine whether adjustment of hydraulic and photosynthetic traits could contribute to this success in both high and low rainfall, we sampled populations on the wet and the dry sides of Hawai‘i Island, replicated on two different-aged lava flows at similar ...
writing an academic article requires the researchers to provide support for their works by learning how to cite the works of others. various studies regarding the analysis of citation in m.a theses have been done, while little work has been done on comparison of citations among elt scopus journal articles, and so the dearth of research in this area demands for further investigation into citatio...
seven rice varieties (hassani, deilmani, sepidrod, shahpasand, saleh, neda, and irfaon215) along with their complete diallel progenies were grown in a randomized complete block design of three replications in the growing seasons of 2006 and 2007 and were evaluated for the quantitative traits of: number of days to flowering, flag leaf length, width and area, plant height, panicle length, extrusi...
in order to study the effect of compost and salinity stress on seedling growth and generative traits of wheat (sivand cultivar) a pot experiment was conducted based on complete randomized design arranged in factorial with six replications at the research greenhouse, faculty of agriculture, mashhad branch, islamic azad university, mashhad, iran, during in cropping season 2013-2014. factors were ...
We report a protocol using a common desk-top scanner and public domain software for measuring existing leaf area and leaf area removed as a result of herbivory. We compared the accuracy and precision of this method to that of a standard leaf area meter. Both methods were used to measure metal disks of a known area, the area of soybean (Glycine max L.) leaves, and the area removed by simulating ...
to investigate the effect of spraying with different concentrations of vermiwash solution on the morphological traits, percentage and yield of essential oil of lemon balm (melissa officinalis l.), this experiment was conducted as randomized complete block design (rcbd) with four replications in experimental field of agricultural faculty of ferdowsi university of mashhad (fum). the treatments we...
