The vase life of cut flowers and foliage is often shortened by vascular occlusions that constrict vase solution supply. Reduction in stem conductivity is typically caused by blockage of cut stem ends and xylem conduits by microbes, physiological plugging, and disruption of water columns in xylem vessels by cavitations and air emboli. Cut flower and foliage longevity can be greatly affected by t...

Silvicultural thinning usually improves the water status of remaining trees in water-limited forests. We evaluated the usefulness of a dual stable isotope approach (d 13C, d 18O) for comparing the physiological performance of remaining trees between forest stands subjected to two different thinning intensities (moderate versus heavy) in a 60-yearold Pinus halepensis Mill. plantation in semiarid...

Carnation is an important traded crop in many countries. Postharvest senescence is a major limitation to the marketing of many species of cut flowers and considerable effort has been devoted to developing postharvest treatments to extend the marketing period. The split-plot experiment was executed based on two factors randomized complete block design with three replications to examine the effec...

lisianthus (eustoma grandiflorum cv. ‘mriachii blue’) is one of the most important and marketable cut flowers in the world. however, a relatively limited vase life reduces its marketability. the aim of the present study was to evaluate the effects of essential oils in extending vase life of cut flowers of lisianthus. for this purpose a factorial experiment based on a completely randomized desig...

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...

tuberose (polianthes tuberosa l.) is an important commercial cut flower that has a short vase life. an experiment was carried out by using five different levels of humic acid (ha) (0, 25, 50, 75, and 100 mg l-1) and seven different levels of silver nano-particles (snp) (0, 0.5, 1, 2, 3, 4 and 5 mg l-1) mixed with 1.5% sucrose on cut tuberosa cv. single flower. the loss of fresh weight on third ...

abstract- chrysanthemum (dendranthema grandiflorum) is one of the most important ornamental plants used as cut flower, flowering pot plant and groundcover worldwide. in this research, the effects of preservative solutions containing thymol (75 and 125 mg -l), menthol (75 and 125 mg l-1) and eugenol (75 and 125 mg l-1) on the quality and vase-life of chrysanthemum cut flowers at 3±1ºc and 75-80%...
