salinity is one of the most important limiting factors for crops, because of most agronomic and horticultural crops are sensitive to salinity. on the other hands, considerable lands of the world were affected by salinity and they are increasing day by day. an experiment was conducted with five levels of irrigation water salinity in soilless culture and greenhouse condition to evaluate the effec...

environmental stress especially drought is one of the most important factors to reduce and disturbance in different stages of floral growth especially sprouting in dry and semi-dry lands of iran. for this purpose a factorial essay executed in accidentally manner with four iterations in vitro condition. four genotypes of bromus tomentellus pasture types were used (92 tehran, 630 kordestan, 3414 ...

In order to investigate the effect of drought and salinity stress on caper plant (Capparis spinosa), a factorial experiment including two factors consisting of drought and salinity levels based on randomized complete block design (RCBD) with five blocks were carried out at College of Agriculture, Shiraz University, Shiraz, Iran. After pretreatment, seeds were germinated in petri dishes and then...

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 ...

transgenic and non transgenic nicotiana tabacum l (cultivar wisconsin) containing ri t-dna were treated with 0, 0.2 and 0.4 mgl-1 ga3 in murashig and skoog medium. some physiological parameters including shoot length, leaf area, number of auxiliary bud, fresh and dry weight, number and length of trichomes were measured. shoot length, fresh weight and dry weight were increased but number of tric...

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 ...

Salinity and heavy metals affect the growth and development of higher plants and also their productivity. In the present study, Cauliflower (Brassica oleracea var botrytis) seeds were allowed to germinate and grow in the absence (control) and presence of different concentrations (50, 100, 250, 500, 750 and 1000 μM) of NaCl, CdCl2, HgCl2 and ZnCl2. Seed germination and growth parameters of seedl...

in the present study, the effect of two species of amf, glomus mosseae and glomus intraradices, alone and in combination, was evaluated on the growth criteria, chlorophyll content, and root rot disease caused by fusarium solani f. sp. pisi, on chickpea (cicer arietinum l.) under greenhouse conditions. chickpea seeds were sown into pots containing 100 g of amf inoculum (more than 1,000 propagule...

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...
