“…Past results revealed that vase life was significantly (P < 0.05) extended from 12.0 days (control) to 24.5 days by using a combination of aluminum sulfate at 300 ppm and sucrose (Amiri et al, 2009). A belief suggests that the maintenance of the carbohydrates pool in flower corolla is one critical factor for senescence delay (Jahnke et al, 2020). The results also corroborate with Sarmah et al (2014) and Sil et al (2017), who recorded similar variations in productivity and vase life among the gerbera cultivars under protected cultivation.…”

Studies on cut flowers have occurred, for improving their quality is the main priority. One of the top 10 cut flowers in the world, the gerbera, or Transvaal daisy (Gerbera jamesonii Hook), is a flowering plant. The presented study aimed to investigate the effect of genotypes, storage duration, and their interactions on the quality of cut flower – Transvaal daisy. Two cultivars of Gerbera (sweet smile and sweet surprise) and their four storage durations underwent examination on the various parameters of vase life and carbohydrates. The results exhibited that the cultivar ‘Sweet smile’ had exceptional values of the studied parameters compared with the cultivar ‘Sweet surprise.’ The treatment of seven days with dry-cool storage proved superior upon 14- and 21-day treatments (11.71, 11.05, and 5.94, respectively) and had the highest positive effects on vase life and flower carbohydrate content compared with the other two storage treatments. The treatment of zero days (non-stored flowers) was significantly superior to seven-day storage. The interactions of cultivars and storage durations gave the highest effect in reducing the depletion of the carbohydrates content in cultivars with zero days, increasing the flower’s vase life. Therefore, the highest values recorded for the cultivar Sweet smile are zero days, followed by seven days of storage, compared with the rest of the treatments.

“…Many cut flowers' petals have levels of free carbohydrates. These levels are notable even when senescence signs happen (Jahnke et al, 2020). Previous thoughts said that maintaining the carbohydrate pool in plant corolla is a relevant factor that delays senescence (Vehniwal and Abbey, 2019).…”

“…Ice formation in peony petal tissue was reported to occur between −3.8 and −4.0 °C for P. suffruticosa [21] and −1.7 °C [62] for P. lactiflora. No freeze injury was reported on cut peony stems of FM, 'Karl Rosenfield', and SB after 5 h at −2 °C [63]. One week of exposure to −3.1 °C likely influenced ice nucleation and caused injury.…”

Cut peonies (Paeonia lactiflora Pall.) have a relatively short vase life and limited availability due to seasonal production. Cultivars Festiva Maxima (FM), Monsieur Jules Elie (MJE), and Sarah Bernhardt (SB) stored at 0.7 °C had a longer flower open time at 12 weeks of storage compared to those held at −3.1 or 3.5 °C, while the flower bud time was unaffected. The flower open time of FM and MJE was no different for stems stored at a sub-zero temperature of −0.6 °C for 16 weeks compared to non-stored stems. Flower quality, opening, and lack of deformity was reduced at 16 weeks of storage in comparison to non-stored flowers, but higher for stems stored at −0.6 °C compared to 0.7 °C. Pre-treating stems before storage with pulses of a commercial hydrator solution or a 200 g·L−1 sucrose solution for 2 h at 4 °C had little commercial significance compared to non-pulsed control stems. The total phenolic content, malondialdehyde, and superoxide dismutase were not effective indicators of open time or quality loss. This study is the first to demonstrate the successful use of a non-freezing, sub-zero storage temperature for peony, and the first to store cut peonies for 16 weeks, despite an increased risk of reduced flower quality.

“…Hardenburg et al (1986), Nichols and Wallis (1972), and Post and Fischer (1952) reported that a number of species, including chrysanthemum (Chrysanthemum), daffodil (Narcissus pseudonarcissus), lily of the valley (Convallaria majalis), gardenia (Gardenia jasminoides), sweet pea (Lathyrus ordoratus), and tulip (Tulipa hybrids), store better at À0.6 C than at 0.6 C. Jahnke et al (2022) showed that tulips could be held at À0.6 C up to 6 weeks with no loss of vase life. and that Dutch iris (Iris ×hollandica) flowers retained their ability to fully expand after prolonged storage at À0.6 C. Additionally, holding cut peony (Paeonia lactiflora) at a sub-zero temperature resulted in faster flower opening without freezing injury or sacrificing vase life and improved the quality of the open flowers (Jahnke et al 2020).…”

The cut flower industry needs postharvest techniques that allow for extended storage of fresh cut flowers to meet consumer demands. We compared the use of a sub-zero storage temperature (−0.6 °C) to maintain viable flowers with improved or comparable vase life to flowers stored at the industry standard (4 °C). The vase life of 17 commercially important cut flower species, alstroemeria (Alstroemeria), anemone (Anemone coronaria), campanula (Campanula medium), carnation (Dianthus caryophyllus), chrysanthemum (Chrysanthemum), delphinium (Delphinium elatum), freesia (Freesia), gerbera (Gerbera jamesonii), gypsophila (Gypsophila paniculata), larkspur (Consolida), lily (Lilium), lisianthus (Eustoma grandiflorum), ranunculus (Ranunculus asiaticus), rose (Rosa hybrida), stock (Matthiola incana), sunflower (Helianthus annuus), and tuberose (Polianthes tuberosa), when stored dry at −0.6 °C for durations of 4, 8, and 12 weeks was comparable to or longer than that when stored at 4 °C. Tuberose stems were not viable after holding for any storage duration or temperature. Experiment 2 compared the use of a prestorage pulsing treatment of water, hydrating solution, or holding solution containing carbohydrates for 8 hours before extended storage for carnation, chrysanthemum, delphinium, lily, and rose stems. Stems of carnation benefitted from pulsing with a hydrating solution and maintained vase life similar to that of nonstored control stems when stored for 4 weeks at −0.6 °C. Conversely, rose stems only maintained vase life similar to that of nonstored control stems when held at 4 °C for all pulsing solutions. Lily and chrysanthemum stems had a decline in vase life with all pulsing solutions and only remained viable after 8 weeks of storage when held at −0.6 °C. Additionally, stored chrysanthemum and lily stems had a longer vase life when stored at −0.6 °C than that when held at 4 °C after 4 and 8 weeks of storage, respectively, with all pulsing solutions. Delphinium stems were not viable after any storage duration. Experiment 3 further evaluated carnation, lily, and rose stems with and without a prestorage acclimation period at 4 °C for either 24 hours or 1 week before extended storage of 4, 6, or 8 weeks. Holding stems at 4 °C for 1 week before extended storage reduced the vase life of all species. Rose stems remained viable after 8 weeks of extended storage when held at −0.6 °C, but only when no prestorage hold was used. Lily and rose stems were not viable beyond 4-week storage durations when held at 4 °C, but they remained viable with no prestorage holding period after 8 weeks at −0.6 °C. Carnation stems maintained a longer vase life irrespective of a prestorage holding period when stored at −0.6 °C. Through this analysis, we showed that many species of cut flowers may be held at a sub-zero temperature with vase life better than or comparable to that with the industry standard of 4 °C.
