“…The results of this work showed that the use of citric acid as a preservative for the cut flowers of AUS, CLC, CRH, and IDF, which were cultivated in the same location (Epanomi or Thermi), did not cause significant alteration in leaf greenness (SPAD values) (Table 4). The above is in agreement with the results of other researchers [55] regarding the effect of citric acid as an additive in cut flower preservatives since a concentration of 100 to 200 ppm citric acid can improve the chlorophyll content of tulip cut flowers to overcome the loss of photosynthetic activity caused by citric acid absorption [56]. However, the addition of citric acid in the preservative solution did not appear to affect anthocyanin leakage [57] and, consequently, the color of flowers.…”

Aiming at evaluating new candidate species for the cut flower market of Greece and beyond, in this study, the vase life of three Greek tulip plant species, Tulipa cretica ‘Hilde’ (CRH, local endemic of Crete, Greece), T. clusiana ‘Chrysantha’ (CLC, naturalized in Chios Island, Greece), and T. australis (AUS, native in the Mediterranean and Greece), was investigated in comparison to the commercial tulip hybrid Île-de-France (IDF). To this end, pre-cooled at 4 °C bulbs of the abovementioned Greek tulip plant species were bought from Dutch nurseries and grown in pots placed in unheated greenhouses located at two different climatic conditions in Northern Greece. The plants were uprooted when the flowers reached a slightly open stage. Half of the flowering stems were immediately placed into bottles with deionized water, while the rest were placed in a preservative solution containing citric acid 5% and sulfuric acid 1% and then remained under laboratory conditions until the entire tepal wilted (end of vase life). The measurements performed concerned: (a) flower stem length and flower maximum diameter, (b) fresh weight (FW) of initial stems, leaves, flowers, and bulbs and at the end of vase life, (c) flower color parameters (L, a, b, c, and H) in all treated flowers, (d) leaf chlorophyll content (SPAD values), and (e) initial and final water volume after removing the flowering stems. The aforementioned measurements showed that CRH cut flowers may exhibit consistent floral opening patterns and were associated with a long mean vase life of 5.7 days, which can be further prolonged to 6.5 days by carefully selecting a cultivation location with proper climatic conditions. The vase life of CLC cut flowers was significantly affected by the climatic parameters (temperature) of the area where the plants were cultivated. The immersion of cut flowering stems in a preservative solution with citric and sulfuric acids did not yield a notable increase in the longevity of cut flowers during the postharvest period. Moreover, this treatment did not have any significant impact on leaf chlorophyll content or flower color at the end of the flowers’ vase life. The data of this work show that cut flowers from the native species T. cretica and T. clusiana have satisfactory vase life, especially when plants were grown in favorable climate condition; the latter is an important criterion for their entry into the cut flower market.

“…Browning is one of the early aging symptoms of cut lily flowers, and their vase life is often determined by the life of leaves rather than that of flower perianths (van Doorn and Han, 2011). In this study, the chlorophyll content in cut flowers of 'Siberia' lily was maintained high by treating them with plasma-activated water that contains hydrogen peroxide, and earlier studies on 'Manissa' lily and tuberose also showed similar results (Liao et al, 2012;Rahimian-Boogar et al, 2016).…”

“…2C). In a study on tuberose, the amount of water absorbed by flowers treated with 648 µM of hydrogen peroxide increased (Rahimian-Boogar et al, 2016). In this study, cut flowers treated with plasma-activated water that contained 600 µM of hydrogen peroxide had a higher ability to absorb water, which indicates that the treatment condition is very effective in maintaining water balance in the plant body.…”

“…It is very important to ensure water flows smoothly, reduce a water loss and maintain a high fresh weight in order to prolong the vase life of cut flowers. Earlier studies on 'Manissa' lily and tuberose reported that treating with hydrogen peroxide is effective in reducing loss in fresh weight and prolonging the vase life of cut flowers (Liao et al, 2012;Rahimian-Boogar et al, 2016).…”

This study was carried out to determine the effect of plasma activated water (PAW) on the postharvest quality of Lilium Oriental Hybrid cv. Siberia. Time-dependent concentration of hydrogen peroxide generated by underwater plasma apparatus was measured. Plasma activated water containing hydrogen peroxide was used as preservative solution and concentration of hydrogen peroxide was 300, 600, and 900 μM (PAW300, PAW600, and PAW900), respectively. The amount of hydrogen peroxide in the plasma activated water increased with increasing the discharge time. Plasma activated water extended flower longevity of 'Siberia' lily more than control. The results of this study show that PAW600 caused an increase in flower longevity, maximum flower diameter, and water uptake. The decline of fresh weight, loss of leaf relative water, and loss of leaf chlorophyll content were also reduced by PAW600 treatment. With increasing the discharged time, the microbial growth in the preservative solution was effectively suppressed, which depends on the concentration of hydrogen peroxide in the plasma activated water. In conclusion, PAW600 treatment could extend flower longevity by suppressing microbial growth in the preservative solution. Therefore, it was concluded that the use of PAW600 as a preservative solution was effective in improving the postharvest quality of cut lily flowers.

“…Despite this physiological response of plants triggered to prevent microbial entry, xylem occlusion by material deposition at the wound site decreases the water absorption capacity of the cut stem, which leads to a reduction in vase solution/water uptake that ultimately affect cut flower freshness and vase life [7,12]. Proteins, polysaccharides, and lignin are considered the main components of vascular blockage in cut flowers [13], and these materials are usually deposited within 5 cm of the stem base [14].…”

Wound-induced xylem occlusion significantly affects the vase life of cut flowers, as oxidative stress and the polymerization of phenolic compounds lead to the deposition of phenolic compounds/secondary metabolites in the stem ends of cut flowers to heal open tissues of freshly cut stems and prevent microbial invasion. However, this deposition causes blockage of vessels, reduced water uptake, and shortened vase life. The physiological plugging of vessels is linked with various oxidative enzymes’ (PAL, PPOs, LACs, and COs) actions taken to increase the synthesis of different compounds, e.g., lignin, suberin, tyloses, gel, and latex, in wounded areas. The use of chemical preservatives/enzyme inhibitors is one of the safest and most efficient techniques employed to minimize vascular blockage and inhibit phenolic compounds deposition and exudation. This review mainly discusses the types of oxidative enzymes, their pathways and biochemistry along with production of secondary metabolites, their biosynthesis, and their modes of action involved in vascular blockage. It also summarizes the different types of preservatives used in postharvest treatments to improve relative water uptake, flower fresh weight, petal protein content, and hydraulic conductance and prolong the vase life of cut flowers during storage. It is hoped that this elaborate study will help researchers in designing new studies concerning occlusion caused by the accumulation of phenolic compounds in vessels.
