“…The data show that there was a positive role for sucrose with or without AgNO3 on preserving the flowers in good condition by inhibiting the chlorophyll retention. Similar results were obtained by Tjosolved, et al [40] and Serek, et al [41], Chatterjee, et al [42], and Singh and Tiwari [26].…”

An experiment was carried out on Taif rose cut flowers cv. (Trigintipetala) to study the effect of pulsing with sucrose and silver nitrate (AgNO3) on vase life and other parameters. In the trial, sucrose and AgNO3 at 4 levels of concentrations (0, 3, 5 or 7% w/v sucrose), (0, 20, 30 or 50 ppm AgNO3) were tested alone as well as combination. The cut flowers were treated in three stages of maturity [bud (B), half opening (H.O) or complete opening (C.O)]. The pulsing times were 5, 10 or 24 hours, then transferred to distilled water as control. The experiment was laid out in a completely randomized design replicated thrice. The sucrose, 7% and AgNO3 30% individually recorded higher vase life of 17.2 and 15 days respectively. Whereas, their combinations (sucrose 7% × AgNO3 30%) was significantly superior to the rest of combination in keeping higher water uptake and retarded the chlorophyll as well as the carbohydrate degradation during the postharvest life and resulting in a highest vase life of 19.1 days.

“…Cytokinins such as BA delay the development of leaf yellowing in a variety of floriculture crops, including lilies (Lilium sp. ), tulips (Tulipa gesneriana), geraniums, gerbera daisy (Gerbera jamesonii), goldenrod (Solidago canadensis), zinnia (Zinnia elegans), and miniature roses (Rosa ·hybrida) (Franco and Han, 1997;Kim and Miller, 2009;Padhye and Runkle, 2008;Philosoph-Hadas et al, 1996;Pinto et al, 2005;Tjosvold et al, 1994). The application of only gibberellic acid, specifically GA 4+7 , also effectively enhances postproduction quality by reducing the occurrence of leaf chlorosis and senescence.…”

Drought stress during the shipping and retailing of floriculture crops can reduce postproduction shelf life and marketability. The plant hormone abscisic acid (ABA) mediates drought stress responses by closing stomata and reducing water loss. Applications of exogenous s-ABA effectively reduce water loss and allow a variety of species to survive temporary periods of drought stress. Unfortunately, s-ABA application can also lead to leaf chlorosis, which reduces the overall quality of economically important bedding plant species, including Viola ·wittrockiana (pansy). The goal of this research was to determine how to prevent s-ABA-induced leaf chlorosis in pansy and a closely related species, Viola cornuta (viola). All concentrations of both spray (250 or 500 mgÁL -1 ) and drench (125 or 250 mgÁL -1 ) s-ABA applications induced leaf yellowing. Young plants at the plug stage and 11-cm finished plants with one to two open flowers were further evaluated to determine if the developmental stage of the plants influenced s-ABA effectiveness or the development of negative side effects. Both plugs and finished pansies and violas developed leaf chlorosis after s-ABA applications, but symptoms were generally more severe in finished plants. The individual application of benzyladenine (BA), gibberellic acid (GA 4+7 ), or the ethylene perception inhibitor, 1-methylcyclopropene, before s-ABA application had no effect on the development of s-ABA-induced leaf chlorosis. However, applications of 5 or 10 mgÁL -1 BA and GA 4+7 as a mixture (BA + GA 4+7 ) before a drench or spray application of s-ABA prevented leaf chlorosis. The application of s-ABA and BA + GA 4+7 would allow floriculture crops to tolerate temporary periods of drought stress without any loss of postproduction quality.

“…Potted miniature roses (Rosa hybrida L.) are popular year-round potted plants, with an increase in production for special days such as Mother's Day and Easter in the United States. However, the leaves of potted roses turn yellow and abscise after pinching (a technique that intends to stimulate branching), as well as under low light conditions after production (Zieslin et al, 1976;Tjosvold et al, 1994). In a previous studies, we used the cytokinin analog thidiazuron (TDZ) as a tool for extending the life of potted plants (Jiang et al, 2009) and preventing leaf yellowing after pinching potted miniature roses (Çelikel et al, 2019).…”

Application of thidiazuron (N-phenyl-N′-1,2,3-thiadiazol-5-ylurea, TDZ), a cytokinin analog, to inhibit the leaf yellowing that occurs after pinching potted rose plants, resulted in compact plants with shorter shoots and thicker internodes. Two weeks after treatment with 100 μM of TDZ, new shoots were half as long as those in control plants, and stem diameters were about 40% greater. This effect of TDZ is associated with changes in cell architecture. Although TDZ treatment stimulated ethylene production by the plants, inhibitors of ethylene biosynthesis (2-aminoethoxyvinyl glycine) or action (silver thiosulfate) did not affect the response of plants to TDZ. We found that TDZ treatment significantly suppressed the expression of bioactive gibberellic acid (GA) biosynthesis genes encoding GA3 and GA20 oxidases and slightly increased the expression of GA catabolism genes encoding GA2 oxidase. Application of GA3 and TDZ together resulted in normal elongation growth, although stem diameters were still somewhat thicker. Our results suggest that TDZ regulates shoot elongation and stem enlargement in potted rose plants through the modulation of bioactive GA biosynthesis.
