“…It was also found that when cut chrysanthemum 'Reagan White' was dipped in 10 mg･L -1 BA solution for 24 hours, their chlorophyll efficiency increased and their vase life was extended (Petridou et al, 2001). When cut Lisianthus and Dahlia treated with 15.8 and 50 mg･L -1 BA respectively, the generation of ethylene was inhibited, and water balance and the turgor pressure of peduncle were maintained, delaying the senescence of the cut flowers (Musembi et al, 2015;Shimizu-Yumoto and Ichimura, 2013). In this study, the group of cut standard chrysanthemum'Jinba' pretreated with 20 mg･L -1 BA for 6 hours showed the most desirable quality.…”

“…In addition, gibberellic acid (GA), 6-benzylaminopurine (BA) and thidiazuron can be used to maintain water balance, inhibit wilting and the creation of ethylene, and maintain the turgor pressure of peduncle. They are effective to maintain the freshness of cut flowers such as Lisianthus (Musembi et al, 2015), Gerbera (Danaee et al, 2012), Iris (Macnish et al, 2010a), and Dahlia (Shimizu-Yumoto and Ichimura, 2013).…”

This study was carried out to examine the effects of NaOCl, sucrose, and BA concentration as pretreatment solution on quality and vase life of cut flowers in Dendranthema grandiflorum 'Jinba'. Flower diameter, fresh weight, and vase life in control and 0 mg･L -1 NaOCl treatments decreased, and the treatment with 100~200 mg･L -1 NaOCl was more effective in the quality and vase life. In pretreatment with 2.5% sucrose solution, flower diameter and fresh weight decreased and vase life was shortest due to the rapid leaf wilting. However, pretreatment with 0.1% sucrose solution increased the flower diameter and fresh weight, and showed the longest vase life. When more than 80 mg･L -1 BA was treated with pretreatment solution, flower diameter and fresh weight decreased, and vase life was shortened. With pretreatment of 20 mg･L -1 BA, the flower diameter was bigger than in the other treatments, but it was no effect on fresh weight and vase life. Therefore, it was suggested that pretreatment solution mixed with 200 mg･L -1 NaOCl, 0.1% sucrose, and 20 mg･L -1 BA was the most effective for the quality and vase life of cut flowers in standard chrysanthemum 'Jinba'.

“…Cut flower senescence is genetically programmed and mediated via hormonal and developmental signaling therefore, vase life of cut flowers would probably be prolonged by reversing the detrimental effects of the senescence-signaling hormones (Musembi et al, 2013) and/or interupting the developmental memory (Musembi et al, 2012). Natural leaf senescence is influenced by various external (e.g.…”

The polyamines, putrescine, spermidine and spermine, are low-molecular weight substances, synthesized in eucariot cells from their immediate precursor, ornithine. The polyamines are found in fruits and vegetables, foods of animal origin and fermented food products. As plant growth regulators, are believed to be involved in several physiological processes. Gibberellins are plant hormones that regulate growth and influence various developmental processes and are derived via the ent-gibberellane skeleton. Gibberellins are synthesized by the terpenoid pathway in plastids and then modified in the endoplasmic reticulum and cytosol until they reach their biologically-active form. Here, we show the importance gibberellin and polyamines functions in plant growth, development, and postharvest senescence of various ornamental plants. Studies initiated on the application of the polyamines and gibberellins in ornamental plants should improve our knowledge in the future.

“…The longevity of the leaves of many species is unsatisfactory; hence, it is necessary to carry out additional post-harvest treatments, which are designed to extend their life after cutting. Ageing is closely associated with the action of growth regulators that accelerate (ethylene, abscisic acid) or delay (cytokinins, gibberellins) this process [3][4][5][6][7][8]. In the case of leaves, compounds from the cytokinin and gibberellin groups play a special role as they inhibit the degradation of proteins and chlorophyll, which directly contributes to delaying the ageing processes [9,10].…”

Synthesis and characterization of bio-based quaternary ammonium salts with gibberellate or l-tryptophanate anion

et al. 2020

Numerous biologically active acids can be transformed into an ionic form in a facile way and combined with appropriate quaternary ammonium cation to improve their application properties or biological activity. This study describes the synthesis of new quaternary ammonium salts with anions of gibberellic acid, a common plant growth regulator from the gibberellin group, or l-tryptophan, an important precursor of auxin biosynthesis. The surface-active tetrapentylammonium ion and natural substances such as acetylcholine, choline, and quinine were the sources of cations. Novel salts of gibberellic acid and l-tryptophan were obtained with high yields exceeding 97% as a result of the metathesis reaction or the neutralization of quaternary ammonium hydroxides. Phase transition temperatures, thermal and chemical stability, and solubility in solvents with different polarities were determined for all obtained salts. On the basis of studies regarding the influence of synthesized salts on the post-harvest longevity and quality of leaves of Convallaria majalis, it was established that the biological activity of the natural plant regulators in most cases was maintained. Therefore, it can be concluded that the conversion of the active substance into the form of a quaternary ammonium salt results in obtaining novel forms of plant growth regulators with favourable physicochemical properties while maintaining the efficacy of the biological active ingredients.
