“…In addition, ethylene inhibitor AVG (Saltveit, 2005) at a lower concentration significantly increased the flower longevity in this experiment, while a higher concentration of 500 ppm AVG had no significant effect. Kılıç et al (2020) reported that ethylene action inhibitor silver thiosulfate (STS) extended the vase life of sunflower cv. 'Sunrich Orange'.…”

This study was carried out to evaluate the effects of different plant growth regulators on the ornamental sunflower plant. The seedlings belonging to Helianthus annuus L. cv. Sunsantion F1 were planted in plastic pots (2 L) containing peat: perlite (1:1, v/v) medium at four true leaf stage. Spray treatments of aminoethoxyvinil glycine (AVG; 250 and 500 ppm), Promalin (5 and 10 ppm), Thidiazuron (TDZ; 5-10 µM), Ethephon (100 ppm) were applied to seedlings 20 days after transfer to the pots, and treatments were repeated 10 days after the first application. Flower life (days), flower diameter (cm), stem diameter (cm) and plant height (cm) were determined. According to statistical analysis, AVG at 250 ppm significantly increased the flower life from 9.17 d in control plants to 11.08 d whereas there were no significant effects on flower diameter and plant height. Both concentrations of Promalin and TDZ increased stem diameter significantly. However, TDZ increased the flower life from 9.17 d (control plants) to 10.36 at 10 µM and 10.33 at 5 µM TDZ. Ethephon application prevented flower bud opening and caused the leaves to be yellowing. These results may suggest AVG and TDZ pre-treatments increase the quality and shelf-life of the potted sunflower plant.

“…However, as a cut flower, it has shown short vase life characteristics, which depending on environmental conditions and cultivar characteristics can range from 4 to 12 days (Sanches et al, 2019;Kılıç et al, 2020). A large part of the cut flowers used in Brazil come from the state of São Paulo (Ibraflor, 2021) and, therefore, in order to increase the time between harvest and commercialization in the different regions of the country, it is important to implement adequate postharvest management techniques that provide better quality and durability of the floral stems, or that the crops are close to the consumer centers (Nascimento et al, 2019;Sanches et al, 2019).…”

The postharvest quality and longevity of cut flowers is influenced by several factors, with the development stage being one of the determining aspects. The determination of the harvest point is variable and must be carried out depending on the physiology of flower development and the proximity of the consumer market. In this sense, the objective was to determine the harvesting point and the ideal stem length for harvesting 'Sol Vermelho' ornamental sunflower. The experimental design adopted was completely randomized, arranged in a 2 × 4 factorial scheme (harvest point × stem length), where stems harvested at stages R4 and R5.5 and in four lengths of 50, 60, 70, and 80 cm were used. The results demonstrate that the early harvest (R4 stage) of the ornamental sunflower flower 'Sol Vermelho' stems is a viable alternative that allows greater post-harvest durability and, consequently, the commercialization of the stems for a longer period of time. In addition, stems harvested at stage R5.5 (open flowers) with lengths of 50 and 60 cm can be recommended for sale in regions close to the production sites.

“…The silver thiosulfate (STS) complex is commonly used as an inhibitor of ethylene synthesis. Application of STS extends the vase life of many cut flowers, such as lily, sunflower, and carnation, but does not significantly extend the vase life of all cut flower types (Liu et al, 2018;Kılıçet al, 2020;Krause et al, 2021). For example, treatment of gardenia cut flowers with STS has no effect on the vase life, and STS treatment of goldenseal cut flowers slightly promotes flower opening but does not extend the vase life (Çelikel et al, 2020;Kato et al, 2022).…”

Metabolome and transcriptome integration reveals insights into the process of delayed petal abscission in rose by STS

The abscission of plant organs plays an important role in ensuring the normal life activities. Rose is one of the most important ornamental plants, and its premature abscission of petal has seriously affected the quality and commercial value. Silver Thiosulfate (STS) is an ethylene inhibitor, which is often used preservative to delay the senescence of fresh cut flowers. To understand the regulatory mechanism of petal abscission in rose by STS, integrative analysis of the metabolome and transcriptome profiles was performed in abscission zone (AZ) tissues of rose under different treatments (MOCK, STS, ETH, STS+ETH). The results showed that STS significantly delayed the petal abscission in phenotype and reduced the activity of two enzymes (pectinase and cellulase) associated with cell wall degradation in physiological level. STS affected the contents of five metabolites (shikonin, jasmonic acid, gluconolactone, stachyose and D-Erythrose 4-phosphate), and involved changes in the expression of 39 differentially expressed genes (DEGs) associated with these five metabolites. Five DEGs (LOC112192149, LOC112196726, LOC112189737, LOC112188495, and LOC112188936) were probably directly associated with the biosynthesis of shikonin, jasmonic acid, and D-Erythrose 4-phosphate. Meanwhile, the effect of STS on the abscission process significantly involved in the pentose phosphate pathway and amino acid biosynthesis pathway. In addition, STS had a greater effect on the transcription factors, phytohormone related DEGs represented by auxin and ethylene, DEGs related to disease resistance and amino acid, etc. Above all, STS negatively influences petal abscission of rose, these results maybe provide a reference for subsequent studies on petal abscission of rose by STS.
