The Effect of Root-zone Physical Properties of Coir and Uc Mix on Performance of Cut Rose (cv. Kardinal)
Rose plants (Rosa x hybrida L. CV. Kardinal, grafted on Natal Brier) were grown in UC mix and in coconut coir. Water release curves and hydraulic conductivity of the media were measured. Water tensions in the media were maintained within a predetermined narrow range by tension-actuated irrigation, using high-flow electronic tensiometers. Transpiration rate of plants sitting on load cells was me...
متن کاملProductivity of three rose cultivars (Rosa hybrida) trained in a `vase-shaped' form and grown in a commercial glasshouse in a Mediterranean environment
A survey was conducted over 12 months to determine productivity and compare the relationships between the different shoot types of three rose cultivars of different ages. The plants were trained in a `vase-shaped' architecture. Data were collected on 1 year-old `Sonia', 8 year-old `Gabrielle' and 7 year-old `Kardinal'. The ratio of basal shoots : branches : shoots ( ̄owering and non̄owering shoot...
متن کاملEffects of Shoot-bending in Relation to Root Media on Cut- Flower Production in Roses
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...
متن کاملEffect of Various Hormones and Different Rootstocks on Rose Propagation
A study was conducted to observe the effects of two hormones viz., Indole Butyric Acid (IBA) and Seradix-A on growth and rooting percentage of Rosa bourboniana cuttings. Experiment was laid out according to Randomized Complete Block Design and there were four treatments, replicated four times. In the second experiment two Rosa species i.e. Rosa bourboniana and Gruss an teplitz were selected as ...
