Nitrate fertilizers are common source of nitrogen (N) in nutrient solutions. Substitution of urea with nitrate could reduce this dependence. Also, nickel (Ni) is essential for activation of urease in plants fed with urea. For this aim, a factorial experiment was conducted in a completely randomized design with four replicates. Urea in five levels (0, 25, 50, 75 and 100 mg/L) and Ni in two level...
In order to study the effects of biofertilizers of nitroxin (0, 2, 4 L.h-1) and biosulphur (0, 2, 4 kg.h-1) Containing “plant growth promotor Bacteria” on quantity and quality of medicinal plant of winter cherry (Physalis alkekengi L.) an experiment in a factorial experiment based on randomized complete block design with nine treatments (Nitroxin 2 and 4 L.h-1, Biosulphur 2 and 4 kg.h-1, Nitrox...
In the commercial production of roses, introducing a method to reduce the time of propagation with maximum success is crucial. This study was conducted to investigate the effect of different concentrations (0, 1500, 3000, 4500 mg/L) of Indole-3-butyric acid (IBA) on propagation of three cultivars of Rosa hybrid L. ('Dolce Vita', 'Samurai' and 'Utopia') by stenting (simultaneous cutting and graf...
The effect of salinity stress on the antioxidant activity of catalase and peroxidase enzymes, relative water content, chlorophyll and carotenoid contents of eight safflower (Carthamus tinctorius L.) genotypes differing in salinity tolerance (4 salt tolerant and 4 salt sensitive) were evaluated. This study was conducted using a split plot design arranged as a completely randomized design replic...
In order to investigate the effects of seed priming by salicylic acid (SA) and Paclobutrazol (Pa) on parsley, as a medicinal plant, under drought stress, a factorial experiment, based on completely randomized design with four replications, was performed at the Research Greenhouse and Laboratory of Department of Horticulture, University of Mohaghegh Ardabili. Experimental treatments included fiv...
The effects of different concentrations of Zinc oxide nano particles (ZnONP; 0, 10, 25, 50, 75 and 100 mg L-1) and Humic acid (HA; 0, 50, 100, 500 and 1000 mg L-1) on root length and number, leaf length and number, bulb diameter, and chlorophyll, total phenol, anthocyanin and flavonoid contents were examined under in vitro conditions. Total phenol, flavonoid and anthocyanin contents were signif...
The reduction of salt toxicity in the soil environment significantly contributes to growth and development plants. In this study, tolerance status strawberry plant were investigated through irrigation solution including 50 mmol L-1 NaCl salinity application mg humic acid (HA). physiological biochemical parameters vegetative fruit stages mineral contents plants assessed if HA contributed mechani...
In this research, the effects of thidiazuron pulse treatment and salicylic acid were examined to improve vase life and maintain the quality of Alstroemeria ҅Modena҆ cut flowers. The experiment was done in a factorial experiment based on RCD with 16 treatments, 3 replications and 48 plots. The flowers were placed in different concentrations of thidiazuron (0, 10, 20, and 50 μM) and salicylic acid ...
in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...
In order to study on different methods of application of polyamines (putrescine, spermine, spermidine) on some morphological, physiological, enzymatic and vase life of Rosa hybrida cv. ‘Dolce Vita’, experiment was conducted as a factorial experiment in a completely randomized design with 32 treatments, 3 replicates and each replication containing 5 vases, a total of 480 vases were executed. Fir...
