Cut-flower production of Rosa hybrida ‘Kardinal’ and ‘Fire and Ice’ were compared between two canopy management regimes: shoot-bending and hedgerow without shootbending, and between hydroponics and non-hydroponic (UC Mix) culture with a tensiometer-based irrigation system. We observed the number and length of all harvestable flowering shoots from September 1997 to August 1999 in order to assess...

plantation of fast-growing species such as poplar is one of the important methods for wood production in the countries with low natural forest areas. physiological differences of populus deltoides clones planted through three decades in shast kalate research forest are unknown. peroxidase enzyme in this research was used for clone separation as a biochemical marker that is sensitive to environm...

this experiment was designed and conducted to increase to yield as well as quality of greenhouse cut-rose. the experiment was conducted in a factorial arrangement, based upon a completely randomized design of three replications, under hydroponic conditions. the study was followed with the aim of investigating the effects of cultivar type (‘bull's eye’-‘cherry brandy’), pot volume (5-8l) an...
