in civil engineering concrete is a material combined of hydraulic cement, sand, gravel and water. gravel and sand compose 60 to 70 percent of concrete. these aggregates support compression force of concrete. cement paste acts as glue to stick grain together. in bushehr factories producing aggregates do not operate according to astm standards, so that fineness modulus (fm) of the produced sands ...
in order to evaluation of plant densities and row spacing effects on growth and yield of wheat, an experiment was conducted by using four plant densities (125, 250, 375 and 500 plants per m2),two row spacing (12.5 and 25 cm), in a randomized complete block design with three replicates in anbare-ololum reign in rainfed and saline conditions during 2008-2009. results showed that leaf area index (...
Maize is an especially well-suited species for studying the effects of aneuploidy on plant development. We used B-A translocations and testers that were crossed seven times into inbred W22 to generate a dosage series for 14 chromosome arms. This is the first report of dosage effects on maize morphogenesis using inbred B-A stocks and inbred tester stocks. We compared plants containing one dose o...
Any altered plant phenotypic expression is a variation that may be desirable or undesirable. Mutants form one such class which has been exploited in past and have role to play in future. One of the aspects in utilizing the worth of mutants is conversion of normal maize into quality protein maize (QPM). In the current investigation we have found a number of plants in the BC2F1 populations whose ...
pot marigold (calendula officinalis l.) is a medicinal and ornamental plant. the effect of different concentrations of chlormequat (cycocel), and daminozide, two plant growth retardant, on plant height, flowering, the content of essence and some other traits in pot marigold (calendula officinalis) was assessed. plant growth retardants are commonly applied to limit stem elongation and produce a ...
Crop production is inherently sensitive to variability in climate. Temperature is a major determinant of the rate of plant development and, under climate change, warmer temperatures that shorten development stages of determinate crops will most probably reduce the yield of a given variety. Earlier crop flowering and maturity have been observed and documented in recent decades, and these are oft...
worship is submission and humitility with believe to divinity in fornt of god. in jewish religion ,worship is submission of the god inall the ordes and devosion tohim .worshio is not only so widely in islam and jew and does not include pray and fast and etc but also is every action that human does with divine intention and to content him. worship has huge and excellent rank in qoran and old te...
the neogene intrusion masses in the noudeh-enghelab area located to the north of sabzevar ophiolite have cut the late cretaceous ophiolitic rocks, sedimentary- volcanic and eocene volcanic rocks and have been covered by pliocene and quaternary deposits. the margin is of lava with basalt, phyric andesite-basalt and andesite and the central parts (dome shaped) composed of phyric andesite-trachyan...
Selection based on proper selection indices can be one of the most effective methods for indirect selection of yield and yield components, simultaneously. In order to determination of selection index for improvement of maize yield, 60 single cross maize hybrids were planted in two separate experiments (drought stress and normal conditions) based on randomized complete block design (RCBD) with t...
Studies of the morphology of the corn plant have led, according to Weatherwax (17) j^ to clearer and simpler explanations of the results of certain experiments with corn. It should be expected that further studies of the developmental morphology might prove to be equally helpful. Variations from the normal sequence of development which lead to abnormalities of the tassel and ear and variations ...
