“…Increase in water uptake could be attributed to inhibition of microbial growth in the end of the stem and vase solution. Similarly, it has been reported that AgNPs treatments increased vase solution uptake in rose flower (L€ u et al, 2010;Nazemi Rafi and Ramezanian, 2013), gerbera (Kazemi and Ameri, 2012), and tuberose (Bahrehmand et al, 2014). Significant effect of EOs on vase solution uptake by suppressing the growth of microbial agents in postharvest life of cut flowers has already been reported (Solgi et al, 2009).…”

Gerbera (Gerbera jamesonii Bolus ex. Hook f.) is one of the most important cut flowers in floriculture industry with high economic value. Short postharvest life is the main barrier for gerbera marketing which is related to water relation disruption resulting from microbial population in preservative solution and exposure to ethylene. Therefore, an experiment was conducted to study the combination effect of an ethylene inhibitor, 1-methylcyclopropene (1-MCP) (0 and 1 μL·L−1), and two antimicrobial agents, ajowan [Carum copticum (L.) C. B. Clarke] essential oil (EO) (0 and 15 μL·L−1) and silver nanoparticles (AgNPs) (0 and 40 μL·L−1), on postharvest life of ‘Pink Power’ gerbera cut flowers. The results showed that stem diameter reduced in both cut stem-end (CSE) and below the flower head (BFH) but the amount of decrease in CSE was more than BFH, and applied treatments had no significant effect on the decrease rate. However, both ajowan EO and AgNPs treatments reduced the number of bacteria at the CSE; ajowan EO was more effective than AgNPs and induced more vase solution uptake. Stem-end electrolyte leakage (EL) was unaffected by 1-MCP treatment, whereas petal EL was lower in 1-MCP-treated flowers. The least wilting percentage and the longest vase life were observed in combination treatment of 1-MCP and either ajowan EO or AgNPs. It could be concluded that 1-MCP combined with ajowan EO or AgNPs, potentially can be used as a preservative solution to enhance postharvest life, delay flower senescence, and prolong vase life of gerbera cut flowers.

Pakistan, growing tuberose is a profitable business as returns are double than cost despite of certain bottlenecks such as fluctuations in the prices and unawareness of farmers regarding its post-harvest handling. Keeping in view high market demand in local flower markets, the present study was conducted to extend the postharvest life of cut tuberose spikes by pulsing cut spikes with various preservatives. Among various pulsing treatments, 10% sucrose plus 50 mg L-1 salicylic acid (SA) for 24 hours proved best with the longest vase life (10.2 d), more number of days required to open 50% florets (5.0 days), maximum dry weight percentage (13.2%) and superior quality spikes (7.6). Moreover, longest florets (7.0 cm) with greater floret diameter (4.2 cm), highest percentage of opened florets (90.0%) and minimum ion leakage of florets (140.0%) was recorded for spikes pulsed with 10% sucrose plus 50 mg L-1 salicylic acid for 24 hours. On the other hand, highest water uptake (106.0 mL) and the maximum relative fresh weight percentage (109.9%) were observed in cut tuberose spikes treated with 50 mg L-1 salicylic acid without sucrose solution. In summary, pulsing of cut tuberose spikes with 50 mg L-1 SA with or without 10% sucrose proved effective for extending vase life and improving postharvest performance of cut tuberose spikes.

“…distilled water (DD), de-Ionized water (DI), reverse osmosis water (ROW), tap water used by the flower retailers at Lahore, Faisalabad, Islamabad or Pattoki flower market, canal water, and carbonated water (7up) + DD (1:1). Measurements: For spike characteristics, data were collected on vase life, time from harvest to the condition when half of the florets were wilted or had bent neck (Ahmad et al, 2011), water uptake, measured in mL on day five of vase life by recording remaining volume of vase water and calculated as: Water uptake (mL) = (S0 -S5), where, S0 is the amount of vase water on day 0 and S5 is the amount of vase water on the day 5 (Kazemi and Ameri, 2012), and relative fresh weight (% of initial FW), on day 5 was calculated as: Water uptake (mL) = (S0 -S5) Where FW5 was the fresh weight (g) of stem on day 5 and FW0 was the fresh weight (g) of the same stem on day 0 (He et al, 2006;Ahmad et al, 2011). Number of days was counted from day 0 to when 50% of the total florets were completely opened on the spike and dry weight of same spike was measured whose fresh weight was measured earlier on day 0 from each replication.…”

Tuberose (Polianthes tuberosa L.), a high temperature tolerant geophyte is being successfully grown with minimal care, which makes it the only choice for the cut flower growers during summer season in Punjab, Pakistan. Currently growers, retailers and consumers hold their cut tuberose spikes in tap water. However, presence of salts in tap water poses threat to cut spikes and may shorten their postharvest longevity. Therefore, a study was conducted to evaluate the effect of water collected from various sources on postharvest longevity and keeping quality of cut tuberose spikes. The results demonstrated that spikes kept in carbonated plus distilled water (1:1) had longest vase life, with highest water uptake, and relative fresh weight. Moreover, it delayed floret opening time, increased open florets percentage and produced superior quality spikes as compared to other water sources. Spikes kept in distilled, deionized and reverse osmosis water also extended postharvest longevity of cut tuberose spikes. On the other hand, canal water or tap water available in local markets found unfit for handling cut tuberose spikes as these reduced vase life. Therefore, it is recommended that carbonated plus distilled water (1:1), distilled, deionized or reverse osmosis water should be used by the stakeholders instead of tap or canal water for extending vase life and maintaining quality of cut tuberose spikes.
