the water deficiency is one of the serious problems in the arid zones. in order to investigate the effect of cycocel on different growth aspects of two olive cultivars (mary and mission), a greenhouse experiment was conducted using three factors of: cycocel at three levels (0, 500 and 1000 mg l-1), irrigation of three levels (irrigated at 5, 10 and 15 days intervals) and tow olive cultivars (ma...

objective(s): electrospun nanofibrous mats of poly(lactic acid) (pla) and nanohydroxyapatite (nano-ha) were prepared and proliferation and differentiation of mesenchymal stem cells on the prepared nanofibers were investigated in this study. materials and methods: pla/nano-ha nanofibers were prepared by electrospinning. the effects of process parameters, such as nano-ha concentration, distance, ...

the autotetraploidy was achieved in basil using tip meristem treatment of seedlings with various concentrations of colchicine solution (0, 0.05, 0.1, 0.2, 0.5 and 0.75% (w/v) ph = 6). a significant increase in the essential oil content was observed in tetraploids as they carry the potential of productivity of 69 % more oil over the diploids. a field experiment was conducted to investigate the e...

Urtica dioica L. is an Iranian native pharmacological plant for which little attention has been paid to the anatomical structure. Medical applications of this plant include diabetes therapy, digestive improvement, anemia and kidney disease therapy. Because climatic conditions can affect the anatomical structure which in turn affects pharmacological compositions, research on the anatomy of this ...

breeding based on selection indices is an effective method for improving complex traits such as yield. to assess the efficiency of different selection methods, 50 genotypes of tall fescue (festuca arundinace) were evaluated under two moisture conditions including full irrigation (normal environment) and deficit irrigation (stress environment). the experiment was conducted according to a randomi...

several plant growth regulators are used to improve the quality of cut flower in bulb plants, but their effectiveness depends on genotype and plant growth conditions such as nutrition status. a pot experiment was conducted under farm condition to study benzyl adenine (ba) and potassium nitrate interaction on floret diameter, stem diameter, flower height, flower number per bulb, fresh and dry we...

in the present study, effect of five isolates of trichoderma harzianum on growth parameters of tomato was carried out as cr design with six replications under greenhouse conditions. the concentrations 0.5%, 1% and 1.5% inoculums per pot were used. plant length, shoot and root fresh/dry weight, number of leaves and stem diameter as growth parameters were measured. the results showed that isolate...

Light intensity is considered a limiting factor in greenhouse rose production. The main aim of this experiment was to evaluate the effect of shading treatments (0, 25, 50, and 65% shading) on quality and chlorophyll content of cut rose (Rosa hybrida cv. Avalanche), under greenhouse conditions. The experiment was planned in randomized completely block design with four replications. All shoots we...
