the postharvest life of cut eustoma grandiflorum flowers is limited in open flowers. therefore a factorial experiment based on a completely randomized design with ascorbic acid (asa) at 4 levels (0, 100, 200, 300mg l-1) and citric acid (ca) at 3 levels (0, 100, 200 mg l-1) with 3 replications and 3 samples for each replications, was conducted for this purpose. results indicated that a significa...

leaf yellowing is a major problem in postharvest of alstroemeria cut flowers. for delaying of leaf yellowing and increasing flower quality a completely randomized factorial design was carried out on the alstroemeria cut flowers (‘fuji’ cultivar). in this research ethanol (0, 2, 4, 6%), ga3 (0, 50, 100, 150 mg/litre) in two methods (pulse and continuous) were investigated on the flower vese life...

The lipid microviscosity of microsomal membranes from senescing cut carnation (Dianthus caryophyllus L. cv. White Sim) flowers rises with advancing senescence. The increase in membrane microviscosity is initiated within 3 to 4 days of cutting the flowers and coincides temporally with petal-inrolling denoting the climacteric-like rise in ethylene production. Treatment of young cut flowers with a...

Consumption of cut flowers is going to increase day by day in Pakistan. It is related with the rising living standards, education and electronic media that have promoted this business in recent years. The production and consumption of cut flowers has increased over the past decade and this increase is expected to continue. However, local consumption and demand is yet to be satisfied. Gladiolus ...

Gerbera(Gerbera jamesonii) from the family of Asteraceae is regarded as one of the best cut flowers in the world. Despite of the publicity of Gerbera’s cut flowers, they have a short postharvest life. The objective of the present study was to study the replacement feasibility and the comparison of thymol (isolated from zataria), and essential oils of peppermint and rosemary (200, 400 and 600 mg...

the asiatic hybrid lily, a bulbous ornamental plant, has a special position in the horticulture as cut flower. to overcome some problems in nutrition of bulb flowers, the use of hydroponic system and nutrient solution is important in the cultivation of these flowers. the asiatic hybrid lilium bulbs “tresor” cultivar, used for the current research were planted under 3 different calcium levels in...

Stem and leaf tissues of carnation (Dianthus caryophyllus) plants appear to contain a natural antisenescence factor since removal of most of these tissues from cut carnation flowers hastened their senescence. However, kinetin (5-10 mug/ml) significantly delayed senescence of flowers with stem and leaf tissues removed. In addition, the life span of cut flowers with intact (30-cm) stems was incre...

Two "thermal dust" fungicides, Termil and Thiabendazole (TBZ), and a liquid, Tutane, were found to be promising in controlling Botrytis disease on cut flowers. They are not only effec tive; they leave no visible residues. Termil and TBZ dusts were more effective than Botran and captan sprays in protecting gladiolus cut flowers from infection. Tutane applied after initiation of infection was mor...
