in order to study the effects of ascorbic acid as an important antioxidant reducing salinity damage, an experiment was conducted on two althernantera genotypes (“entire leaf” and “undulated leaf”) at research greenhouse of shahid chamran university in 2013. concentrations of 0, 0.5 and 1 mm of ascorbic acid were sprayed weekly on plants grown under 0, 30, 60, 90 mm nacl. the experiment was carr...
Seaweed extract can improve the physicochemical properties of the soil and has a favorable effect on the plant growth and development due to having high nutrient content, high water holding capacity, plant growth regulators and beneficial microorganisms. The aim of this experiment was to investigate the effect of Ascophyllum nodosum extract, a brown alga, on the morphophysiological characterist...
the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
background: biostimulants are amino acids and organic components, which can play main role in the plant growth and dry matter accumulation. objective: determine the influence of foliar application of active amino acids on quality and quantity yield of melissa officinalis l. methods: this study was conducted in a research farm at the institute of medicinal plants on the base of randomized comple...
This study was undertaken to identify morphological changes in young seedlings of 5 Iranian almond species (Prunus dulcis, P. eburnea, P. eleagnifolia, P. haussknechti, and P. scoparia) under polyethylene glycol-induced drought stress. Drought stress caused a significant reduction in plant growth parameters such as fresh and dry weights of plant organs, leaf number, total leaf area, and leaf re...
In this research, to evaluate the effect of superabsorbent polymer and drought stress on the number and leaf area of Lettuce, experimental research was conducted in a completely randomized design factorial with two treatments of irrigation regime at three levels (60, 80 and 100 percent of crop water requirement) and four superabsorbent hydrogel application (0, 4, 6 and 8 g per kg of soil) in t...
this study purported to compare and contrast the use of self-mention and evidentials as two mtadiscourse features in opinion columns of persian and english newspapers. the theoretical basis of this study is the idea that metadiscourse features vary across cultural boundaries. for this purpose, 150 persian and 150 english opinion columns were collected based on three factors of topic, audience a...
some of the morpho-physiological characteristics related to the leaf growth and development of phaseolus vulgaris l. genotypes have been studied in the field conditions at the seed and plant improvement institute (spii). the study was performed as split plot experiment in a randomized complete block design with four replications in well-watered and water deficit conditions with eight genotypes ...
The present study was aimed to investigate the response of the growth and physiological parameters of stevia (Stevia rebaudiana Bertoni) medicinal plant to salinity stress using a pot experiment in 2014. Ten levels of salt stress (0, 30, 60, 90, 120, 150, 180, 210, 240 and 270 mM of NaCl) were arranged in randomized complete block design with three replicates. Regression analysis of data indica...
In order to investigate the effects of spent mushroom compost and grafting on growth and yield of greenhouse tomato cv. Synda, a factorial experiment based on completely randomized design with 5 replications was carried out in Greenhouse of Mohaghegh Ardabili University in 2012. Tomato plants as scion, grafted on Synda and rootstocks of Yedi and Kingkong, and none-grafted plants (as...
