Sweet basil (Ocimum basilicum) was planted and grown using both a gravel filtration and floating raft method in order to determine which produced the greatest biomass. Basil was also grown under the same conditions in soil as a control. The growth period was 30 days at which point the total biomass was measured and weighed (wet weight). The gravel filtration method produced the greatest biomass...

Application of nitrogen sources in nutrient solution of soilless culture systems is one of the important factors in rose production. In order to investigate the effects of different ratios of nitrogen (N) source in nutrient solution on mineral concentration and vase life of rose (Rosa hybrid L. cv Dolcvita), an experiment was conducted as a randomized complete block design in a commercial green...
In order to improve the quality of cut rose ‘Dolce Vita’, an investigation was performed with 20 treatments, 3 replications, and 2 plants in each replicate in a greenhouse with the open soilless culture system. The treatments included control (distilled water), putrescine (Put) at the rates of 1, 2 or 3 mM, spermidine (Spd) at the rates of 0.5, 1 or 1.5 mM, spermine (Spm) at the rates of 1, 2 o...

Production of medicinal crops in soilless culture systems and controlled environments provides an opportunity for increasing the quantity and quality of primary materials of medicinal plants. A factorial experiment based on completely randomized design was carried out with four culture systems (aeroponics, nutrient film technique, classic hydroponics and soil) and three different nitrogen sourc...
Fungal and oomycete populations and their dynamics were investigated following the introduction of the biocontrol agent Pythium oligandrum into the rhizosphere of tomato plants grown in soilless culture. Three strains of P. oligandrum were selected on the basis of their ability to form oospores (resting structures) and to produce tryptamine (an auxin-like compound) and oligandrin (a glycoprotei...
