“…Decreased amounts of ethylene receptors enhance ethylene sensitivity (Cancel and Larsen, 2002;Hada et al, 2009;Tieman et al, 2000), consistent with the down-regulation of CaETR4-like by 1-MCP application (Figure 7) (Ha et al, 2019;Mata et al, 2018;Wu et al, 2017), thereby promoting anthesis.…”

“…The inhibition of ET production by STS has been previously observed in cut Eustoma flower ( Ichimura et al, 1998 ). Similar to STS, the ET-action inhibitor 1-MCP also reduced ET production in cut rose, carnation, and lotus flowers by the suppression of ACS1 , ACS2 , and ACO1 ( Imsabai et al, 2010 ; In et al, 2013 ; Ha et al, 2020 ). Recently, Wang et al (2020) and Wongjunta et al (2021) observed that STS inhibited ET production in lotus leaves and orchid flowers by suppressing the expression of ACS and the activities of ACS and ACO enzymes.…”

Ethylene Acts as a Negative Regulator of the Stem-Bending Mechanism of Different Cut Snapdragon Cultivars

et al. 2021

This study investigated whether ethylene is involved in the stem-bending mechanism of three different snapdragon cultivars ‘Asrit Red’, ‘Asrit Yellow’, and ‘Merryred Pink’, by treating their cut stems with an ethylene-releasing compound (ethephon), an ethylene-action inhibitor [silver thiosulfate (STS)], and distilled water (as the control). Ethephon completely prevented stem bending in all cultivars, whereas STS exhibited a higher bending rate compared with the control. The bending rates were influenced by several factors, such as the degree of stem curvature, relative shoot elongation, ethylene production, and lignin content, indicating their involvement in the stem-bending mechanism of the cultivars. The analysis of the expression of genes involved in the ethylene and lignin biosynthetic pathways also supported the importance of lignin and ethylene in the stem-bending mechanism. Taken together, as ethephon completely prevented stem bending of the three snapdragon cultivars, this study suggested that ethylene acts as a negative regulator of the stem-bending mechanism of snapdragon cultivars, and the information will be valuable for the prevention of stem bending in other commercially important ornamental flowers.

“…Numerous preservatives, such as silver thiosulfate (STS), have been studied and applied to reduce postharvest disorders and enhance the vase life of cut flowers [7][8][9][10]. STS has a strong antagonistic effect on ethylene binding and antibacterial activity, and it has been widely used to retard senescence and extend the postharvest life of cut flowers [7,10].…”

“…However, the effect of AIB on postharvest quality of cut roses has not been well studied. In addition, 1-methylcyclopropene (1-MCP) is an inhibitor of ethylene action that has been found to improve the vase life and postharvest quality of various flower species including roses [9,13,14]. Previous observations showed that 1-MCP has a greater affinity for the ethylene receptors than ethylene [15]; therefore, 1-MCP effectively suppresses ethylene binding to the receptors and blocks the action of downstream components in ethylene signal transduction within plants.…”

Flower senescence varies among cut roses (Rosa hybrida L.), and it is known that the postharvest life of ethylene-sensitive flowers is strongly related to the transcriptional accumulation of ethylene biosynthesis genes, whereas that of ethylene-insensitive flowers is shortened by water stress. These different responses of flowers to hormone and water stresses limit the action of preservatives in inhibiting the postharvest deterioration of cut rose flowers. This study was conducted to investigate the effects of the combined application of antibacterial agents and ethylene biosynthesis and binding inhibitors on the postharvest life and quality of the cut rose cultivars ‘Matador’ (ethylene-sensitive) and ‘Dolcetto’ (ethylene-insensitive). Cut flowers were treated with nano silver (NS), a combination of NS and α-aminoisobutyric acid (NS+A), or a combination of NS+A and 1-methylcyclopropene (NS+AM), and they were subsequently exposed to ethylene for 24 h. Treatment effectiveness was compared with that of control (CON) flowers, which were kept in distilled water and exposed only to ethylene. The results showed that all treatments significantly improved the postharvest quality and vase life of both rose cultivars. However, NS+AM most markedly delayed senescence and prolonged the vase life of cut flowers by 217% in ‘Matador’ and 168.4% in ‘Dolcetto’, compared with those of CON flowers. NS+AM also effectively increased the flower diameter and maintenance time of positive water balance and initial fresh weight by enhancing solution absorption as well as suppressing bacterial growth at the cut stem ends of the cut roses. Furthermore, NS+AM greatly suppressed the ethylene-inducible increase of ethylene biosynthesis genes and the reduction of ethylene receptor genes in petals, which resulted in a reduced flower response to exogenous ethylene in both rose cultivars. These findings show that NS+AM effectively delays flower senescence in both ethylene sensitive and insensitive cultivars by synergistically preventing ethylene response and water stress in cut flowers.
