laboratory and field experiments were conducted to investigate the relationships between germination characteristics and field emergence in produced seeds of soybean cultivars as affected by under three different soil moisture conditions. the treatments are included water stress [irrigation plants after 50 (normal irrigation), 100 (mild stress), 150 (severe stress) mm evaporation from class a p...
The purpose of this research was to determine the effects of different silicon concentrations on the physiological and morphological characteristics of purple basil under drought stress conditions. For this purpose, a factorial experiment based on a completely randomized design with three replications was done. The studied factors were four levels of drought stress (25, 50, 75, and 100% full ir...
the objective of the present study was to investigate the effects of high dietary levels of l-arginine during starter period on growth, intestine morphology and immune system of female ross broiler chicks. in this experiment, 192 day old female ross broiler chicks were fed with 4 dietary treatments in a completely randomized design, in which each dietary treatment included 4 replications. dieta...
abstract in order to evaluate the effects of drought stress and defoliation on sunflower, a study was conducted under controlled conditions. treatments were a combination of three levels of drought ((100, 60 and 30 percent of field capacity (fc)) and three levels of defoliation (control, removal of either 4 or 6 leaves from lower part of the plant) laid out, in a completely randomized design wi...
to study the effect of different concentrations of potassium in thenutrient solution and water stress on the quality and quantity yield of lilium la cv.termoli, a pot experiment was conducted based on completely randomized design in sand and perlite medium (50:50) in three levels of potassium (kfree, 6 mm k and and 12 mm k in hoagland solution) with three replications. in the present study, the...
Salinity is one of the most extensive environmental stresses and is a limiting factor for the growth and development of crops, such as rice. Then, an experiment based upon completely randomized design with four low levels (0, 7.5, 15, 22.5) and four high of salinity (75, 150, 225 and 300 mM) with control as the first factor and nine cultivars of rice (dollars, Hasan Saraii, Mousa Tarom, Kamfiru...
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...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
abstract in order to investigate the effect of different ratios of cocopeat and vermicompost as a cultural media on seed emergence and some qualitative and quantitative characteristics of sweet pepper transplant (cv. colifornia wonder). the treatments include: vermicompost + cocopeat (3:1), vermicompost + cocopeat (1:3), vermicompost + cocopeat (1:1) (v/v) and normal soil of transplant. the tre...
salicylic acid (sa) plays a key role in plant disease resistance and hyper-sensitive cell death but is also implicated in hardening responses to abiotic stress. the aim of this study is to examine the effects of salicylic acid on the growth, eco-physiological and biochemical characteristics in zinnia elegans plant exposed to copper stress. effects of copper (cu) on biomass, root length and shoo...
