“…vest disorders of cut carnations are generally attributed to ethylene damage. Nonetheless, they are at least partially related to water deficit (Liu et al, 2018;van Doorn, 2012). Water deficit symptoms in many cut flowers, including carnations, are the result of stomatal water loss that gradually exceeds the rate of water uptake through the xylem vessels in the cut-stem ends (Mattos et al, 2017;van Doorn, 2012).…”

Leaf stomata are the main channels for water loss of plants including cut flowers. In this study, we investigated the organographic distribution, morphological characteristics, light–dark response, and water loss contribution of stomata in cut carnations (Dianthus caryophyllus L. ‘Master’), which are prone to typical water deficits despite a few and small leaves. Stomata were observed in the upper and lower leaf epidermis, stem surface, abaxial bract epidermis, and abaxial sepal epidermis. Stomatal density (SD) on the stem surface was the highest and significantly greater than that on the upper and lower leaf and abaxial bract epidermis. The sepal epidermis had the lowest SD and the smallest stomata whereas the upper leaf epidermis had the largest stomata. Changes in the water loss rate increased in the light and decreased in the dark in both intact and leaves-removed cut carnations. The water loss rate of the former was greater than that of the latter. However, the water loss rate for the stem-only cut carnations had weak change rhythms and was much lower than that for the intact and leaves-removed cut carnations. These findings demonstrate the differential contributions of stomata in leaves, stems, and floral organs to water loss, and help to elucidate further the mechanism underlying postharvest water deficit in cut carnations.

“…Dianthus caryophyllus L., commonly known as carnation, is one of the most popular cut flowers; it ranks third after chrysanthemum and rose in the worldwide market (Liu et al, 2018). Vegetative propagation by cutting is one of the main methods used for D. caryophyllus seedling production, which is economically important for highscale breeding of elite commercial genotypes from stem cuttings of the mother plants (Garrido et al, 1998).…”

In this study, Dianthus caryophyllus L. was used as the experimental plant to investigate the effects of rooting substrate and exogenous auxin concentration on the adventitious rooting of the stem cuttings. Our results showed that the formulated substrates with different physicochemical properties significantly affected the root formation. The substrate with a ratio of cocopeat to perlite at 1:1 (v:v) resulted in the optimum rooting of D. caryophyllus cuttings. Different Indole-3-butyric acid (IBA) and 1-naphthalene acetic acid (NAA) concentrations affected the rooting percentage and seedling rate of D. caryophyllus. Application of NAA at 1000 mg·kg−1 with IBA at 100 mg·kg−1 resulted in the greatest rooting percentage and improved breeding speed. The rooting percentage and seedling rate did not increase with the increase in auxin concentration. Based on these results, we concluded that an appropriate rooting substrate is required to fulfill proper rooting of D. caryohhyllus cuttings, whereas an exogenous application of IBA and NAA at 1000 mg·kg−1 and 100 mg·kg−1 promoted the rooting and a higher auxin concertation inhibited rooting.

“…On the other hand, NS and antibiotics have a good synergistic activity that has high inhibition against K. pneumoniae 39 . In addition, several studies have shown that NS has outstanding ability to maintain the freshness of cut owers, con rming its excellent germicidal effect and antagonizing effect against ethylene 6,7,10,11 . Four dominant bacteria (Arthrobacter arilaitensis, Kocuria sp., Staphylococcus equorum, and Microbacterium oxydans) that reduce vase life were isolated from the stem ends of cut carnation owers, thereby proving that biosynthetic NS treatments signi cantly inhibit bacterial growth in the vase solution and cut stem ends of owers and foliage during their vase life 12,26 .…”

The green synthesis of nano-silver (NS) has gained increasing attention owing to its cost-effectiveness and environmental friendliness. Herein, we have described a novel one-step green preparation method of stable NS aqueous solution using Tollens reagent as the silver ion source, D-fructose as the reduction agent, and polyvinyl pyrrolidone (PVP) as the stabilizing and capping agent. The optimum preparation parameters were 40 mL 10 g L−1 PVP, 100 mL 0.116 mol L−1 D-fructose, and 200 mL 0.001 mol L−1 Tollens at a reaction temperature of 25 °C for 2 h. The prepared NS solution had a pH value of 7.10, with approximately spherical NS particles in the range of 13.95–87.36 nm. The resulting NS solution was stable under normal temperature, boiling water bath, and acidic environment; however, it did not exhibit stability under an alkaline environment. The NS solution had a remarkable absorption peak at 410 nm in its ultraviolet visible spectrum. Moreover, it exerted strong inhibitory effect on the growth of the bacteria isolated from the vase water of cut carnation ‘Prince’ flowers. These findings indicate that the obtained NS aqueous solution is potentially a practical and effective antibacterial agent for preserving cut carnations and other cut flowers.
