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 ...
In order to investigate effect of nitrogen fertilizer on yield and quality of three forage sorghum cultivars under Guilan climatological conditions a field study was conducted in 2010 cropping season at Rasht. A randomized complete block design with factorial arrangement with three replications was used. Treatment consisted of four levels of nitrogen fertilizer (0, 50, 100 and 150 kg N ha-1 fro...
this study was conducted to evaluate the effect of municipal waste compost leachate (mwcl) on capsicum annum plant and chemical properties of a clay loam soil with five ratios of mwcl to irrigation water (0, 20, 40, 60 and 100 percent) treatments each with three replications by using a completely randomized factorial design under greenhouse condition. electrical conductivity, organic matter...
seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
the main objective of this study was to determine the effects of plant growth promoter bacteria on biomass and yield of basil. the experiment was carried out as randomized complete blocks design with eight treatments and three replications at research field of agriculture company of ran in firouzkuh of iran in 2012 . the treatments were [1] azotobacter chroococcum (a), [2] azospirillum lipoferu...
Pistachio is one of the most important commercial trees grown in Iran arid and semi-arid regions. Salt stress has been reported to cause an inhibition of growth and development, reduction in many plant characteristics. Adverse effects of salinity on growth, and characteristics of pistachio have demonstrated. Salicylic acid (SA) is known to have an affect on normal conditions and stresses in pla...
Actual yields of cumin plant harvested by farmers are at level much below attainable yield potential. Among many growth factors zinc and ferrous was recognized as one of main limiting factors of crop growth and yielding. In order to study the effects of zinc and iron foliar application on yield, yield of cumin (Cuminum cyminum), with factorial experimental in completely randomize block design w...
thyme (thymus vulgaris l.) is an aromatic and medicinal plant which is very important for the herbal industry. in this research, in vitro selection for nacl tolerance was investigated in this plant. hypocotyl and shoot explants (apical meristem and cotyledonary leaves) of sterilized seedlings were cultured in ms medium supplemented with different combinations of 2, 4-dichlorophenoxyacetic acid ...
Nowadays induction of polyploidy using mutagenic chemicals to increase secondary metabolic production as a modification method of pharmaceutical plants is very usual. A factorial experiment based on completely randomized design with three replications was carried out on Sistan's native fenugreek (Trigonellafoenum_graecum). Colchicine concentration in four levels (0.2, 0.5, 0.75 and 1 gl-1) and ...
in order to investigate the effect of pruning and potassium nutrition on pumpkin grain yield and quality, a factorial experiment based on complete block design with four replications was carried out in nooshar village of ardabil province, ardabil, iran, in 2007. experimental factors include potassium nutrition in three level (0, 75 and 150 kg/ha from potassium sulfate) and stem pruning (without...
