Postharvest studies were carried out in three varieties of (Gerbera jamesonii Hook.) cvs. Primrose, Malibu and Sunway to find out the effect of growing seasons (autumn, winter and spring) on the vase life of cut flowers during September 2009 to March 2010. Laboratory experiments were carried out in controlled room having 18±2°C temperature, 68±2% relative humidity and 100 lux light. The study revealed that the longest vase life was noticed in Sunway, followed by Primrose and Malibu. Regarding the season of production, longest vase life (18.37 days) was found in the flowers harvested in winter, followed by spring (14.8 days) and autumn (9.57 days). The interaction effect of season and variety showed that longest vase life (23.2 days) was found in Sunway harvested in winter whereas the shorter vase lives (5.7 and 7.8 days) were in Malibu and Primrose respectively harvested in autumn. Stalk length (57.88 cm) and floral diameter (10.78 cm) were highest in autumn while diameter of the stalk (0.64 cm) was the highest in spring. Sunway had the highest floral and stalk diameters, while the stalk length was longer in Malibu and Primrose. Total water uptake during the vase life was highest in flowers grown in winter (34.9 ml), followed by spring (34.7 ml) and autumn (26.14 ml).

During the vase life of cut stems obstruction of xylem vessels occurs due to microbial growth, formation of tyloses, deposition of materials in the lumen of xylem vessels and the presence of air emboli in the vascular system. Such obstructions may restrict water uptake and its transport towards upwards thus lowering their ornamental value and longevity of cut flowers.Clematisis a very attractive plant material which may be used as cut flower in floral compositions. Nothing is known about the histochemical or cytological nature of xylem blockages occurring in cut stems of this plant. This study shows that inclematis, tyloses are the main source of occlusions, although bacteria and some amorphic substances may also appear inside the vessels. A preservative composed of 200 mg dm−38-HQC (8-hydroxyquinolin citrate) and 2% sucrose arrested bacterial development and the growth of tyloses. This information can be helpful in the development of new treatments to improve keeping qualities of cutclematisstems.

Stem Bending

The respiration of cut flowers of gerbera (Gerbera jamesonii H. Bolus ex Hook.f. `Vesuvio') and sunflower (Helianthus annuus L.) increased exponentially with increasing storage temperature. Poststorage vase life and negatively gravitropic bending of the neck of the flowers were both strongly affected by simulated transport at higher temperatures. Vase life and stem bending after dry storage showed highly significant linear relationships (negative and positive, respectively) with the rate of respiration during storage. The data indicate the importance of maintaining temperatures close to the freezing point during commercial handling and transport of these important commercial cut-flower crops for maximum vase life.

In studying the postharvest water relations of cut flowers, researchers aim to determine rates of water uptake and water loss along with changes in fresh weight. An automatic apparatus was devised for continuous monitoring of these indices. The novel apparatus consists of two balances automatically recording mass at a relatively high data acquisition rate (min−1), a personal computer, two containers, and plastic tubing. The apparatus is accurate, labor-saving, and real-time. It enabled dynamic synchronous recording of water uptake as well as fresh weight of the cut flower stem, from which precise water uptake loss rates during vase life can be accurately determined. Rates of water uptake and water loss of individual cut rose (Rosa hybrida cv. Movie Star) stems were measured using the apparatus under alternating 12-h light and dark periods. Both water uptake and water loss rates fluctuated with the light to dark shift over 120 h of observation. Stem fresh weight increased rapidly over the first 40 h of vase period and decreased gradually thereafter. Cut lily (Lilium hybrida cv. Yellow Overlord) stems showed similar trends in water uptake and water loss rate to cut rose stems. The accuracy and sensitivity of the new apparatus was validated by comparison with manual weighing using a balance at 2-h intervals under alternating 12-h light and dark periods over 108 h. The apparatus described here constitutes a suitable method for direct measurement of water uptake and fresh weight, including capturing relatively rapid water balance responses to changes in the postharvest environment.

The postharvest longevity of fresh-cut flowers is often limited by the accumulation of bacteria in vase water and flower stems. Aqueous chlorine dioxide is a strong biocide with potential application for sanitizing cut flower solutions. We evaluated the potential of chlorine dioxide to prevent the build-up of bacteria in vase water and extend the longevity of cut Matthiola incana `Ruby Red', Gypsophila paniculata `Crystal' and Gerbera jamesonii `Monarch' flowers. Fresh-cut flower stems were placed into sterile vases containing deionized water and either 0.0 or 2 μL·L–1 chlorine dioxide. Flower vase life was then judged at 21 ± 0.5 °C and 40% to 60% relative humidity. Inclusion of 2 μL·L–1 chlorine dioxide in vase water extended the longevity of Matthiola, Gypsophila and Gerbera flowers by 2.2, 3.5, and 3.4 days, respectively, relative to control flowers (i.e., 0 μL·L–1). Treatment with 2 μL·L–1 chlorine dioxide reduced the build-up of aerobic bacteria in vase water for 6 to 9 days of vase life. For example, addition of 2 μL·L–1 chlorine dioxide to Gerbera vase water reduced the number of bacteria that grew by 2.4- to 2.8-fold, as compared to control flower water. These results confirm the practical value of chlorine dioxide treatments to reduce the accumulation of bacteria in vase water and extend the display life of cut flowers.

Xylem Blockage

During vase life of cut flowers obstructions in stem xylem vessels develop. Such obstructions may restrict water uptake in stems and its transport towards flowers, thus lowering their ornamental value and longevity. <em>Clematis </em>is a very attractive plant which can be used as a cut flower in floral compositions. However, nothing is known about the histochemical or cytolo- gical nature of xylem blockages occurring in cut stems of this plant. Observations carried out on <em>Clematis </em>cv. 'Solidarność' proved that tyloses appeared as a principal source of xylem blockage in cut stems. The preservative composed of 200 mg × dm-3 8-HQC (8-hydroxyquinolin citrate) and 2% sucrose arre-sted development of xylem blockage, while the vessels in stems kept in water were filled with tyloses or an amorphic substance. PAS reaction proved that polysaccharides were present in the xylem occlusions, whereas no homogalacturonans were immunolocalized in tyloses using JIM 5 and JIM 7 antibodies. The present study provides new information on the origin of xylem occlusions in clematis and their development in two different vase solutions. Such information can be useful to develop pro- per postharvest treatments aiming to improve keeping qualities of this new cut flower.

Preservative Solutions

Efficacy of preservative solutions on vase life of garden roses has not been researched before. Vast variability and morphological characteristics of this group of roses are very important, making them suitable for their use in bouquets, arrangements and vases. This research was carried out to examine the influence of five preservative solutions on vase life of garden rose cut flowers. The aim of research was to determine best preservative solution for prolonging of vase life of garden rose cut flower. The experiment included 8 rose cultivars cultivated for garden use. Each treatment consisted of 10 cut garden roses. The cut garden rose flowers with vase solution containing Al2(SO4)3+ethanol+sucrose register longer vase life and higher values in water uptake. Vase life of flowers held in tap water (control) was lowest (4.38 days). This research backs the assumption that with the use of preservative solutions, garden rose also can be used as a cut flower.

Snapdragon (Antirrhinum majus L. `Chitchat'), delphinium (Delphinium ajacis L. `Bellisimo'), chrysanthemum (Dendranthema grandiflora RAM. `Regan'), tulip (Tulipa hybrid `Golden Brush'), gerbera (Gerbera jamesonii H. Bolus `Manovale'), oriental lily (Lilium asiaticum L. `Specisiom Simplon'), rose (Rosa hybrid L. `Carnavale') and iris (Iris hollandica Tub. `Blue Magic') cut flower stems were placed at 20 °C in water containing the NO donor compound 2,2'-(hydroxynitrosohydrazino)-bisethanamine (DETA/NO) at 10 and 100 mg·L-1 and after 24 h, transferred to humidified air containing 0.1 μL·L-1 ethylene. Compared with flowers kept in water, the vase life of all eight flowers was extended by DETA/NO with an average extension of about 60% with the range being about 200% for gerbera to 10% for chrysanthemum. DETA/NO appears to have widespread applicability to cut flowers and offers a simple technology to extend vase life.

Continuous postharvest treatment of cut rose flowers (Rosa hybrida L. cv. Diana) with maleic acid hydrazide (1.2-dihydro-3,6-pyridazinedione, MH) at 560.5 8-hydroxyquinoline sulfate (HQS) at 388.4 HQS, MH + HQS or sucrose + HQS treatments. The longevity of flowers in MH + sucrose in combination with HQS was extended for 18 days after vase treatments, whereas the longevity of cut flowers was only 4, 6 and 8 days for HQS, MH + HQS and sucrose + HQS, respectively. Cut roses treated with MH + sucrose + HQS in vase solution exhibited greater water uptake and less water loss than those in HQS. The concentrations of various sugars in petals were highest in the sucrose + HQS treatment, and MH + sucrose + HQS > MH + HQS > HQS. Ethylene production was significantly lower in sucrose + HQS or MH + sucrose + HQS treatments in comparison to MH + HQS, or HQS.
