This experiment was conducted to study the effects of application of partial root zone drying technique on quantitative and qualitative characteristics of strawberry (Fragaria ananassa cv. Selva). The experiment was arranged as randomized complete blocks design with five treatments and four replications. One week after planting the seedlings, different irrigation regimes including FC: FC (moist...
structure. So, it is possible to achieve the salinity-tolerant genotype in plants through creating changes in the genetic structure and breeding activities. Tomato is in the group of plants sensitive to salinity stress. Distinct studies have been explained different indicators for tolerance to salt stress in tomato. Identifying a reliable indicator in the early stages of plant growth under salt...
in order to evaluate the effects of beneficial free living bacteria (azotobacter chroococcum and azospirillum brasilense) compared to different nitrogen fertilizer levels on yield and yield components of barley (hordeum vulgare cv reyhan) a field experiment was conducted at research station college of agriculture, ferdowsi university of mashhad in 2007-2008. the experiment was arranged in a ran...
This experiment was conducted in a greenhouse at Isfahan University of Technology, Isfahan, Iran in 2014 to evaluate 20 wheat cultivars (Navid, Pishtaz, Karaj, Kavir, Tajan, Karun, sholeh, Bahar, Khoshki 11, Gasparood, Sepahan, Sorkh tokhm, Chamran, Ghods, Shariar, Omid, Sistan, Alamut, Marvdasht and Shiraz) under two carbon dioxide concentrations (the ambient 360 and the enriched 700 µM) and t...
This study was conducted to evaluate the effects of paclobatrazol and cycocel on some quantitative and qualitative traits of zinnia. Seedlings were transplanted on Horticulture Department Farm , College of Agriculture, Isfahan University of Technology. The experiment was carried out in the framework of randomized complete block with 3 replications. Triats which were studied included plant heigh...
The aim of this research was to investigate the root colonization percentage of grain sorghum cultivars by two species of mycorrhizal fungi and its effect on some of morphological and agronomic traits. Experiment was laid out as factorial based on randomized complete block design with three replications. Experimental treatments included three levels of fungi (F1: control without inoculation, F2...
in order to evaluate the effect of different levels of salinity and three nitrogen nutrition on biochemical reactions and changes in dry weight of shoot and root on psyllium (plantago ovata f.), a glasshouse experiment in a complete randomized design with three replications in 2009 at university of zabol was conducted. salinity treatments in this experiment were 0, 100 and 200 mm of nacl and ni...

in order to study the effect of pyridate, bentazon and imazethapyr herbicides on chickpea growth, nodulation and biological nitrogen fixation, a greenhouse experiment was conducted at ferdowsi university of mashhad in 2010. experimental type was completely randomized design with four replications. treatments included pyridate, bentazon and imazethapyr herbicides application in 1200, 720 and 75 ...
Waterlogging reduces shoot and root growth and final yield of wheat. Waterlogged sites have a combination of low slope, high rainfall, heavy texture and low permeability. This study was aimed the importance of waterlogging on root growth and wheat yield. In order to study the effects of different waterlogging duration (0, 10, 20 and 30 days) at growth stages (1-leaf stage, tillering stage and s...
