CULTIVAR COMPARISON OF BUDDLEIA AS A CUT FLOWER

Buddleia sp., butterfly bush, is a large, arching shrub with spike-shaped inflorescences in a wide range of colors including pink, purple, yellow, and white. Our objective was to determine which cultivars of Buddleia had an acceptable postharvest life and potentially could be used as cut flowers. Stems of `Black Knight', `Charming Summer', `Empire Blue', `Lochinch', `Nanho Blue', `Nanho Purple', `Pink Delight', `Royal Red', `White Profusion', and `Sungold' were harvested when one-third to two-thirds of the florets had opened. Within 2 hours of harvest, flower stems were recut under water, placed in vases containing 10 g Floralife/liter, and placed in a simulated consumer environment. Daily fresh weight, open and total length of inflorescence, and inflorescence color were measured. `Charming Summer', `Pink Delight', `Royal Red', `Sungold', `Lochinch', `White Profusion', and `Nanho Blue' performed best.

Number Of Stems

Several cut flower species were studied to determine their feasibility for cut flower production. Three fertilizer treatments (0.5, .1, and .15kg/m2 respectively) were used and their effect on number of stems, stem length and fresh weight were determined. Celosia cristata and Ageratum houstonianum `Blue Horizon' proved to respond best to fertilizer treatments. Celosia fertilized at a rate of .15kg/m2 will produce approximately 200 stems/m2. Ageratum will produce appoximately 400 stems/m2 when fertilized at a rate of .10kg/m2. Fertlizer rates of .10 and .15 kg/m2 for Eustoma culture yielded 86 stems/m2, which was lower than other species used in this test. Extended vase life and consumer response could possibly justify using this species in cut flower production. An economic break-even analysis will be presented to show what price will have to be received per stem to cover costs.

Loss Rates

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.

Preservative Solutions

The short vase life is the major problem in the cut flower industry. This study was conducted to evaluate the role of different vase solutions and oils in enhancing the quality and vase life of lily cut flowers. Salicylic acid (SA; 300 mg L−1), citric acid (CA; 300 mg L−1), gibberellic acid (GA; 100 mg L−1), and clove oil (200 mg L−1) were used as vase solutions. These treatments were applied after pulsing with preoptimized sucrose 5%. It was found that SA (300 mg L−1) + sucrose (5%) improved the performance of cut flowers, which further increased the longevity of all tested lily cultivars up to eight days and the longest vase life by 17.6 days. The maximum change in fresh weight (5.60 g), increase in chlorophyll contents (3.2 SPAD value), highest protein content (6.1 mg g−1 FW), and increase in the activities of superoxide dismutase (SOD) (51.0 U g−1 protein), catalase (CAT) (36.3 U g−1 protein), and peroxidase (POD) (41.6 U g−1 protein), were recorded with the CA (300 mg L−1) + sucrose 5%. Among the cultivars, “Zambesi” performed best compared to “Sorbonne” and “Caesars”. The maximum anthocyanin contents (198%) were recorded in “Caesars”. In conclusion, among the different preservative solutions, SA performed best to prolong the vase life and quality of lily cut flowers.

This investigation was carried out to study the effect of 100, 200 and 300 ppm 8-hydroxyquinoline sulphate (8-HQS) and 5 and 10% sucrose treatments on the vase life and post-harvest quality of cut flowers of Strelitzia reginae Ait. and Hippeastrum vittatum Herb. cv. Apple Blossome. All possible combinations of 8-HQS and sucrose were tested. The treatments were applied as holding solutions, and control flowers were held in distilled water till the end of the experiment. All the treatments significantly increased the vase life and number of open florets of Strelitzia reginae cut flowers compared to the control. Applying 8-HQS and sucrose treatments in both seasons improved the vase life and floret longevity of Hippeastrum vittatum cut flowers. In addition, the percentage of fresh weight gain from the initial weight and the carbohydrate content were also enhanced in both cut flower crops. In order to obtain the highest post-harvest quality of Strelitzia reginae Ait. and Hippeastrum vittatum Herb. cv. Apple Blossome cut flowers, treatment with 200 ppm 8-HQS + 10% sucrose was recommended.

Areas Of Interest

Efforts to improve postharvest longevity of fresh-cut flowers has only recently turned toward selection and breeding. Conventional methods to extend keeping longevity of cut flowers depend on use of chemical treatment placed in holding solutions. Postharvest longevity studies were initiated with Antirrhinum majus L. (snapdragon) to determine: if natural genetic variation existed for cut-flower longevity, the inheritance of the trait, heritability, and associated physiology. Evaluation of commercial inbreds held in deionized water revealed a range in cut-flower longevity from a couple of days to 2.5 weeks. The shortest- and longestlived inbreds were used as parents in crosses to study the aforementioned areas of interest. Information will be presented on inheritance of cut flower longevity based on populations evaluated from matings for generation means analysis and inbred backcross method. Also presented will be information on stomata, transpiration, carbohydrate, fresh-weight change, and forcing temperature relative to postharvest longevity.

Cut flowers of a short (S)-lived (3-day) inbred, a long (L)-lived (15-day) inbred and their hybrid (F1, 7.3 days) of Antirrhinum majus L. were evaluated for fresh weight and ethylene evolution change postharvest when held in deionized water. Fresh weight change of all accessions increased 1 day postharvest then declined over the remainder of postharvest life. The loss of fresh weight was most rapid for S and less rapid for F1 and least rapid for L. Ethylene release postharvest for S and F1 started on day 1, but for L ethylene release started on day 9. Once ethylene evolution began it continued through postharvest life. On the last day of postharvest life, ethylene release from S and F1 were similar, but L was twice the level as S and F1. It appears that a slower decline in fresh weight, a delay in outset of ethylene release and higher final amount of ethylene release at senescence are heritable and associated with longer keeping time of A. majus.

Postharvest Life

Research shows differences among flowering species in ethylene sensitivity in response to ethylene inhibitors, including silver thiosulfate. Buddleia sp. is an arching shrub with spike-shaped inlforescences in a wide range of colors, including pink, purple, yellow, and white. The objective of this study was to determine optimal pulsing time of silver thiosulfate to maximize the postharvest life of five cultivars of Buddleia sp.: `Empire Blue', `Lochinch', `Nanho Blue', `Pink Delight', `Royal Red', and `Sungold'. Flower stems harvested at 1/3 to 2/3 development were transported to a simulated consumer environment. Stems were recut under water and pulsed for 0, 30, 60, and 120 min prior to placing them in a solution of deionized water and Floralife at 10 3 g·liter–1. No silver thiosulfate treatment was more effective than the control at extending vaselife, increasing floret development, or increasing stem fresh weight.

Strategies to prevent postharvest losses include the use of genotypes that have a longer life. The objective of this study was to develop a screening test for the estimation of cut flower postharvest life and the response to exogenous ethylene of different carnation cultivars at an early stage of plant growth. Ethylene sensitivity and production in different cut flower cultivars was evaluated, and a similar response in the vegetative stage was studied. Also, the possible relationship between the morphological parameters of cuttings and flower postharvest life was studied. Ethylene production of cuttings may be a useful tool for estimating ethylene production of cut flowers. There is a strong relationship between cut flower vase life and the root length of cuttings, as well as cut flower ethylene sensitivity and the number of internodes the cuttings have. Applications of exogenous ethylene to cutting cultivars have an effect on the growth parameters of the cuttings, but the response to ethylene in cut flowers does not behave in the same way in the vegetative stage.

Compare And Contrast

Floricultural producers, cut flower wholesalers, mass market retailers and general retailers were surveyed to compare and contrast the industry in terms of attitudes and problems. Questions involved general business information, as well as specific crops. Overall, all four segments of the industry were neutral to negative on potted flowering plants, but were positive to neutral on bedding and foliage plants. However, producers were slightly negative concerning the postharvest life of bedding plants. While cut flower wholesalers had a positive attitude concerning cut flowers, retailers and mass marketers tended to be neutral to negative. In particular, retailers and mass marketers felt cut flowers were too expensive and too short lived. Floral preservatives were used by 81.6% of general retailers, while only 18.8% of mass market retailers used preservatives. All cut flower wholesalers used preservatives. Capital availability and market demand were the factors most limiting to expansion for producers and general retailers; mass market firms listed competition as their most limiting factor. Results from other questions will also be provided.

Flowers of Craspedi a uniflora (Billy Buttons), a New Zealand annual plant, have been introduced recently into the U.S.A. florist market. Craspedia is relatively unknown in the U.S.A., but is beginning to be utilized by florists as a cut flower and has potential for specialty cut flower production. Craspedia uniflora cut flowers were grown from seed in an inflated, double-layer, polyethylene greenhouse. Short day (SD) and long day (LD) photoperiod treatments were applied by daylength reduction via black cloth and night interruption lighting, respectively. Treatments began 10 weeks after sowing (15 leaf stage) and continued until harvest. Gibberellic acid was applied as a single foliar spray to runoff at 0 and 500 mg·liter-1 at initiation of photoperiod treatment. Long day treatment reduced days to anthesis, increased flower number, and decreased stem length and plant fresh weight. Gibberellic acid (500 mg·liter-1) increased foliage height under both photo period treatments and increased plant dry weight under LD but reduced dry weight under SD treatment. Flower fresh weight, diameter and bud number were not affected by treatment.
