Flower Quality

Cut-flower production of three snapdragon (Antirrhinum majus L.) cultivars (`Potomac Pink', `Winter White', and `Potomac Light Pink') in growing trays vs. ground beds was evaluated in five different plantings over a period of a year and a half. The experiments evaluated the quality of cut flowers from plants in ground beds or in small vs. large trays either raised or placed directly on the ground bed. The quality of flowering shoots was lower when plants were grown in raised trays rather than in on-ground trays or in ground beds, but other treatments did not affect quality consistently. Flowering shoot grade (a subjective quality indicator) correlated well (r = 0.8) with the ratio of shoot dryweight to shoot length (an objective quality indicator). Our results confirm that the flower quality of snapdragons grown on ground trays can equal that of those grown in ground beds.

And Control

Flowering induction and control is a limiting factor when commercially producing cut flowers of lisianthus and seed exposure to low temperatures, a physiological event called vernalization, induces the differentiation of vegetative buds to reproductive buds, contributing to a flowering that is uniform and has quality. The objective of this study was to evaluate the influence of seed vernalization in three cultivars of lisianthus (Excalibur, Echo and Mariachi) for 12, 24, 36 and 48 days at temperatures of 5, 10 and 15°C, in the production and quality of buds, making this technology feasible to large-scale production. During cultivation it was observed that the lower the temperature and higher the vernalization period, the lower the cycle and the greater the number of plants induced to flowering for all three cultivars, and those are important features in the context of flower production in a commercial scale. The seeds subjected to vernalization originated plants that produce flower stems within the standards required by the market, showing that vernalization was efficient to induce flowering without affecting the quality of the buds. To produce lisianthus as a cut flower of quality, it is recommended seed vernalization of Mariachi and Echo cultivars for 24 days at 5°C and Excalibur for 36 days at 5°C.

Sampai saat ini mutu bunga sedap malam (Polianthes tuberose L.) yang diproduksi oleh petani kecil belum dapat memenuhi mutu sesuai kebutuhan pasar. Penurunan mutu bunga sedap malam diduga berkaitan dengan kurangnya keseragaman diameter tangkai bunga, bentuk tangkai bunga, dan sebagainya. Penelitian ini bertujuan mendapatkan informasi mengenai karakteristik mutu bunga potong sedap malam komersial di sentra-sentra produksi. Mutu bunga sedap malam sangat ditentukan oleh ukuran tangkai bunga dan kesegaran bunga. Penelitian dilakukan sejak bulan Juli 2006 sampai  dengan Februari 2007. Sampel bunga potong sedap malam dipanen dari daerah Cianjur (Jawa Barat), Bandungan (Jawa Tengah), dan Pasuruan (Jawa Timur) masing-masing sebanyak 100 tangkai untuk diamati karakteristik fisiknya, yaitu panjang tangkai bunga, diameter bunga, panjang bunga, warna, dan kesegaran bunga. Hasil penelitian menunjukkan bahwa bunga potong sedap malam dari daerah Jawa Timur adalah tipe bunga tunggal dengan jumlah bunga per malai 49,1 ± 8,2, stadia kemekaran bunga 1,6±0,5, dan diameter tangkai bunga 10,8±1,5 cm. Aroma bunga sangat tajam, dengan penampilan lebih ramping dibanding bunga potong sedap malam asal Jawa Barat dan Jawa Tengah. Informasi mengenai mutu bunga potong sedap malam  sangat bermanfaat bagi pedagang atau eksportir untuk mendapatkan produk yang diinginkan pasar atau konsumen.<br /><br /><br /><br />Quality of tuberose cut flowers which are produced by small farmers until now has not enough to fulfil market demand. The decrease of tuberose cut flower quality is believed to be related to unavailability of stalk diameter and other flower characteristics. The aim of the study was to determine quality characteristics of fresh tuberose cut flowers harvested from  farmer field  in production centers. Tuberose cut flowers quality is mainly affected by the flowers size and freshness. The research was conducted from July 2006 to February 2007. Tuberose cut flower were freshly harvested at farmer  field in Cianjur (West Java), Bandungan (Central Java), and Pasuruan (East Java), 100 samples collected from each district. The cut flower samples were observed and evaluated for physical appearance i.e. length of flower stalk, diameter, color, and freshness. The results showed that the tuberose cut flower from East Java was a single type with flower number 49.1 ± 8.2, the number of opening flower 1.6 ± 0.5, stem diameter 10.8 ± 1.5 cm. The aroma of the flowers was very keen compared to slimmer appearance of delicate tuberose cut flowers from West Java and Central Java. The information of tuberose cut flowers characteristics will benefit to saler or exporters to obtain the product that demanded by market and consumers.

Anthurium andraeanum flowers quality and productivity depend on the fertilizer, and the growing media used. Most Brazilian anthurium growers use to prepare their growing media, but they do not realize that the low quality and productivity might come from an inadequate mix that they are using. So, the objective was to determine yield and flower quality of anthurium plants grown in different growing media and fertilizations. 'Eidibel' anthurium plants were grown in: a) pine bark + composted organic matter (1:1); b) wood shavings + composted organic matter (1:1); c) growing media usually utilized by the grower where this study was developed (a mixture of soil, coal residue and composted cow manure). Four fertigation solutions were applied weekly during eleven months. These solutions were: NPK 100% (5.00: 1.64: 3.12 g plant-1 year-1); N and K 100% + P 150% (5.00: 2.46: 3.12 g plant-1 year-1); N and P 100% + K 150% (5.00: 1.64: 4.70 g plant-1 year-1); N 100% + P and K 150% (5.00: 2.46: 4.70 g plant-1 year-1). These were compared with monthly fertilization done locally with slow releasing solid fertilizer (4.52: 1.23: 4.99 g plant-1 year-1). Although there was no increase in the yield, represented by the number of flowers produced per plant, the growing media prepared with wood shavings + organic compost (1:1) with all fertilization tested produced the best quality anthurium cut flowers (Extra and Class I).

Insight Into

Thirty cut flower businesses were surveyed in 1997 to examine the production structure and main problems of export-oriented contract growing in Turkey. The survey was conducted in Antalya province, which is the center of export-oriented cut flower production in Turkey. The results of the research provided insight into how Turkish cut flower-contracted growers were managing some of the key areas of their operations. The study also provided the opportunity for growers to highlight their concerns about contract growing for export-oriented cut flower production. The survey showed that contract growers do not use specific performance indicators relevant to cut flower production. The product price received by the contract growers was determined by the export companies. These export companies receive flowers from growers mainly on consignment. After exporting the products, exporters periodically pay the grower, subtracting a commission for their services and other marketing expenses. Contract growers are essentially price takers in the transactions. The business procedure from production to price setting and marketing was not in the hands of the contract growers. Therefore, the trading risks are essentially borne by the contract growers. The main concerns raised by contract growers were the current consignment system, cost of the plant materials, and the late payment for the sold products.

The aim of this work is to evaluate the reuse of municipal wastewaters treated through subsurface constructed wetlands (SS-CWs) as irrigation water in cut flower aeroponic cultivation under arid conditions. For this purpose, two experimental aeroponic cultivation systems were installed with the cut flower Lilium ‘Tresor’ planted and irrigated with SS-CWs treated water. The results showed that the quality of the SS-CWs wastewater has to be improved to be used in irrigation. Despite that, Lilium ‘Tresor’ grew under arid conditions with normal stem diameters and number of flowers but with heights under 0.65 m, which would restrict their commercialization to local markets. Water electrical conductivity (> 2300 µs/cm) and luminosity (> 120 klux) were factors that affected plant height. When compared to other cultivation systems, the aeroponic cultivation system used between 10 % and 20 % of the amount of water needed to produce Lilium ‘Tresor.’ Thus, this work showed the feasibility to produce cut flowers using an aeroponic cultivation system under arid conditions and irrigated with SS-CWs effluents. Likewise, it was detected that improvements to water quality and luminosity must be made for industrial scaling.

Introduction: The procedure to synthesize silver nanoparticles (SNPs) from Prunus cerasoides leaf extract and their effect on vase life and flower quality of cut carnation were investigated. Methods: SNPs were bio-synthesized from Prunus cerasoides leaf extract and characterized by using UV-Vis technique, TEM, and SEM images. The postharvest responses of carnation cut flowers to the biosynthesis SNPs were evaluated through vase life, relative fresh weight, vase solution uptake, flower diameter of cut carnation. Results: SNPs were synthesized under optimum conditions, including using the extract of leaf heating at 60 oC in 30 min, 4 mM of silver nitrate, pH of 11, and 180 min of reaction time. SNPs exhibited antimicrobial activity and then alleviated the bacterial development in the preservative solution. All treatments with SNPs had improved the vase life and quality of cut carnation compared to the control. A vase solution containing 2% sucrose enhanced the carnation cut flowers. Conclusions: The preservative solution containing 25 ppm SNPs and 2% sucrose showed the best effect. SNPs could be used as a promising antibacterial agent applied in the preservative solution for cut carnation flowers.

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.
