in order to evaluate the effects of different levels of water and plant density on yield, yield components, morphological and physiological characteristics of a new corn hybrid (ksc 500), an experiment was carried out in 2006 in karaj area. the experimental design was split plot based on randomized complete blocks design with three replications. main plots were three irrigation levels: 75%, 100...
abstract: about 60% of total premium of insurance industry is pertained?to life policies in the world; while the life insurance total premium in iran is less than 6% of total premium in insurance industry in 2008 (sigma, no 3/2009). among the reasons that discourage the life insurance industry is the problem of adverse selection. adverse selection theory describes a situation where the inf...
Breeding programs strategies depends on genetical mechanism of selection traits. In the present research, generation mean analysis with joint scaling test was performed to determine the gene action. F1, F2 and F3 generations, derived from Roushan and Kavir cross along with their parents were sown in a partial Lattice design with two replications under stress condition at the research field of S...
ABSTRACT: Leaf area is an important growth variable in agricultural crops and the leaf main of interest tobacco industry. So, aim this scientific research was to estimate Burley by linear dimensions leaves determine which mathematical model more adequate for purpose. Two experiments were carried out with tobacco, cultivar DBH 2252, 2016/2017 2018/2019 years, respectively, municipalities Itaqui ...
Mathematical models based on dynamic growth process of greenhouse melon leaves were built. Two experiments, involving different years, organic fertilizer rates and cultivar types in melon, were carried out for data acquisition. In each experiment, time-course observations of leaf morphological properties (leaf length and leaf width) on different leaf positions of melon were obtained. The result...
In order to study the effect of organic and chemical fertilizers on some agronomical properties of burley tobacco, an experiment was carrid out in a randomized complete block design with six fertilizer treatment and three replications at the research field of Shahrekord University in 2013. Fertilizer treatments were including of: control, chemical fertilizer equal 100 percent of tobacco needs, ...
background & aim: kelussia odoratissima mozaff. (apiaceae) is one of the medicinal plants and endemic in zagros mountains, iran, which unfortunately due to illegal harvest is endangered. in order to break dormancy and to evaluation of effect of different treatments on traits a factorial experiment base on completely randomized design was created on the seed zone sar-aghaseyed functions in c...
in the turfgrass industry, the need for salinity tolerant turfgrasses is increasing because of the increased use of saline and non-potable water. greenhouse container experiments were conducted to determine the relative salinity tolerance and growth responses of eleven native populations of tall fescue (festuca arundinacea schrub) (tf), including: semirom, mashhad, sanandaj, yasuj, yazd abad, d...
abstract venlafaxine, 1–[2–(dimethylamino)–1–(4–methoxyphenyl) ethyl]cyclohexanol hydrochloride is a novel non-tricyclic antidepressant. venlafaxine is a second generation antidepressant drug, has a neuropharmacologic profile distinct from that of existing antidepressants including tricyclic compounds, selective serotonin reuptake inhibitors and monoamine oxidase inhibitors. venlafaxine impart...
This study developed an efficient and reliable system for inducing polyploidy in Anoectochilus formosanus Hayata, a top-grade medicinal orchid. The resulting tetraploid gave a significant enhancement on various agronomic traits, including dry weight, fresh weight, shoot length, root length, leaf width, the size of stoma, and number of chloroplasts per stoma. A reduction of the ratio of length t...
