Biochar reduces the bioavailability of a wide range of pollutants, especially heavy metals (HMs).To evaluate the effects of waste biochar of cutflower rose on growth characteristics and accumulation of lead (Pb) and cadmium (Cd) HMs of in lettuce, a factorial experiment, based on completely randomized design, with four replications was conducted. The amount of rose biochar at 3 levels (0, 5 and...
Soil and water salinity substantially constrain crop and biomass production. To investigate the changes in morphological parameters of lisianthus (Eustoma grandiflorum) cultivars under CaCl2 salinity conditions a greenhouse experiment was conducted. Cultivars namely, ‘Champagne’ (C1), ‘Lime Green’ (C2), ‘Blue Picotee’ (C3) and ‘Pure White’ (C4), were subjected to salt stress (0–30 mM CaCl2) in ...
oil contamination is one of the most common and usual kinds of pollution in aquatic and terrestrial ecosystems. one of the economical and effective methods for decreasing or eliminating oil contamination is using plants and microorganisms. soils contain a wide variety of oil decomposing microorganisms, of which pseudomonad, rhodocoous and nocardia are the most important. to evaluate the effect ...
Abstract In order to study of the effect of substrates on vegetative and ecophysiological characteristics of coleus plant, coleus cuttings containing two leaves were planted in perlite, cocopeat, peatmoss, compost, 50% perlite + 50% cocopeat, 50% perlite + 50% peatmoss, 50% perlite + 50% compost, 5% cocopeat+50% peatmoss, 50% cocopeat + 50% compost and 50% peatmoss + 50% compost with four repl...
ABSTRACT- Heat stress causes flower and fruit abscission in pepper. This study was conducted in the greenhouses of Isfahan University of Technology to evaluate the effect of foliar application of Benzyl adenine (BA) and potassium silicate (K2SiO3) under heat stress condition on bell pepper. Two factorial experiments based on completely randomized design with four concentrations of BA (0, 0.06, ...
Plants deal with various stresses like salt stress in their life. Henbane is one of the important plants of potato family with numerous pharmaceutical effects. To assess the effects of salinity on growth responses of Henbane plant, experiment performed in growth chamber as pot culture based on a randomized complete design (CRD) with three replications. Seed germination percentage has been studi...
Salinity is one of the most important factors limiting agricultural production. Cotton, as an oil-fiber plant, is one of the most important industrial plants and is sensitive to salinity, especially at germination and seedling stages. Therefore, in this study, 14 allotetraploid varieties of commercial and local cotton were selected. The study was carried out as factorial with a completely rando...
Several species of Phytophthora cause crown and root rot diseases of herbaceous and woody plants. Crown and root rot of pistachio trees cause significant damages in infected orchards. The effect of foliar application with Elite (fosetyl-Al) in 2 and 2.5 g/l was evaluated in greenhouse experiments. The frequency of mortality, fresh and dry weight of roots and shoots, height, intensity of crown r...
Seed priming is the most important technique for increasing the germination power. This study was conducted to investigate the effects of halopriming and hydropriming on improvement of seed germination in black locust (Robinia pseudoacacia L.) in a completely randomized design with 4 replications. Halopriming treatments of KNO3 with concentrations including (100, 250, 500, 750 mM) and hydropr...
In order to evaluate the genetic variation in Iranian summer savory accessions, different accessions were analyzed using multivariate and univariate analysis. Results indicated that there were significant differences in some traits. The mean comparison analysis using least significant difference (LSD) test revealed significant differences among the accessions understudy. In this regard, the hig...
