Delaying of Postharvest Senescence of Lisianthus Cut Flowers by Salicylic Acid Treatment
Salicylic acid (SA) is considered to be plant signal molecule that plays a key role in plant growth, development, and defense responses. The physiological mechanism of exogenous SA to affect the senescence of cut lisianthus flowers during vase life was investigated. Fresh cut lisianthus flowers were treated with distilled water (control), 0.5, 1 and 2 mM SA and then held at 25◦C up to 12 days. ...
متن کاملDifferential expression of several xyloglucan endotransglucosylase/hydrolase genes regulates flower opening and petal abscission in roses
Flower opening is a process that requires movement of petals from a closed position to a horizontal open position, while petal abscission requires cell-wall disassembly. Both processes are controlled by ethylene and require cell-wall modification at the junction (abscission zone) of the petal and thalamus to facilitate the movement or separation of petals. In the present study, a family of xylo...
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 کاملNitrate and potassium uptake by greenhouse roses (Rosa hybrida) along successive flower-cut cycles: a model and its calibration
Rose (Rosa hybrida L.) plants grown for cut-flower production in greenhouses produce flowers in flushes year-round. Crop models for this system must handle the cyclical nature of productivity, which is determined by the horticultural production methods. Nutrition was not accounted for in previous rose growth models, since little is known about uptake of the essential nutrients by rose roots. Th...
