“…These results are considered controversial, according to Reid (2004), stating that the best temperature range for long term storage of S. reginae is 6 to 7°C; and Nowak and Rudnicki (1990) stated 8°C for a period of 4 weeks. The useful life of scapes floral S. reginae is 10 to 15 days (Jaroenkit et al, 2008) and according to Bayogan et al (2008), 6-16 days.…”

Cut flowers have a very limited life after they have been cut off from the mother plant, as survival on their own reserves is generally low due to the special morphological and physiological characteristics of their tissues. The use of refrigeration for storage of flower cuttings is very important because it reduces water loss, senescence, infections caused by bacteria and fungi, thus extending the shelf-life of flowers during the storage period. Therefore, the aim of the present work is to show differences between requirements of various species of flowers during refrigerated storage.

“…For example, in lily inflorescences, the use of 5% sucrose in the conditioning solution allowed the harvest of inflorescences at earlier stages, enabling flower bud opening and longer pot life (Barbosa et al, 2005). The use of pulsing with sucrose is effective to extend calla lily opening and longevity (Almeida et al, 2008;2011), as well as bird-of-paradise (Bayogan;Jaroenkit;Paull, 2008), Agapanthus praecox (Burge et al, 2010) and Bougainvillea glabra (Moneruzzaman et al, 2010).…”

Preservative solutions on quality and biochemical aspects of calla lily flowers

The knowledge of physiological and biochemical aspects occurring at the postharvest phase of flowers is critical to guide efficient conservation techniques for maintaining quality and longevity. Factors that cause deterioration of cut flowers after harvest are dehydration, low carbohydrate contents, the presence of microorganisms in vase solution or stem and late stage of development at harvest. Thus, the objective was to determine the effect of harvest stages of calla lily stems and storage solutions on water relations and contents of starch and sugars. Flower stems were harvested in the following opening stages of the spathe: early-stage (cartridge) and 1/3 open and were arranged in six storage solutions containing 1, 2, 4 and 6% glucose and the controls with water and solution with 5% sucrose. Results indicate that at early-stage and 1/3 open harvesting stages, the addition of glucose at concentrations of 4% and 6% stimulated flower opening. Calla lily flower stems maintained in water and in solution with 1% glucose had lower percentages of fresh weight loss and better maintenance of water balance, with a small reduction in the contents of starch and soluble sugars. The addition of sugars in the storage solution was efficient in opening early-harvested stems. Harvest the floral stems in initial stages allow the maintenance of the commercial quality for longer period, without pollen production. The use of water relations allowed the determination of the better sugar concentration for the conservation of open-harvest of floral stems.

“…The perianth is formed by six tepals distributed in two groups, with three external equal and free tepals, and the other three unequal and generally welded, one of which has larger dimensions and is folded in the shape of an arrow surrounding the style. The gynoecium presents three welded carpels, and the ovary is infernal, trilocular, and with numerous seminal primordiums [1][2][3][4][5][6]. The fruit is a valvicidate capsule that opens by three valves.…”

The flower of Strelitzia reginae generates abundant and viscous mucilage as exudate, which is purified in periods of heating–cooling, and finally precipitated with ethanol, obtaining strelitzia gum (StrG). By means of intrinsic viscosity measurement, the viscometric molecular weight (MWv) is determined, with a value of 200,000 g/mol, as well as a hydrodynamic radius of 20 ± 1 nm and a hydration value of 445 ± 34 g/g. The size of StrG was compared against dynamic light scattering data with a value of 16 ± 2 nm and a MWDLS of 230,000 g/mol. StrG is a biopolyelectrolyte with an “a” value of 0.85, which corresponds to a flexible behavior with a great effect of volume exclusion. This statement is based on the difficulty of gum dissolution, that should be performed at 80 °C. This macromolecule is very promising and can potentially be used in several industrial applications, such as in film forming, and as a gel, thickener, and coemulsifier.
