“…In tulip, petal opening and closure occur concomitantly with water transport and are regulated by reversible phosphorylation of aquaporins (Azad et al, 2004). In addition, we have shown that cellloosening proteins, xyloglucan endotransglycosylase/ hydrolase (XTH) and expansions are important in petal growth (Yamada et al, 2007(Yamada et al, , 2009. The functions of these proteins in rhythmic flower opening will be an intriguing theme hereafter.…”

Some flowers including rose open in a rhythmic fashion during specific times of the day. We used time-lapse cinematography to understand the mechanism of rhythmic opening and perception of light in cut rose flowers. Cut rose flowers exposed to a 12 h light/12 h dark photoperiod started opening shortly before the light period had begun and stopped during the light period even when their leaves were removed, indicating that petals and/ or sepals perceive light and synchronize flower opening to photoperiods. This rhythmic opening could be seen in constant darkness even though the time of flower opening shifted to an earlier point in constant darkness compared with the 12 h photoperiod, but it was not observed in constant light. We also evaluated the effect of exposing cut flowers first to a 12 h photoperiod and then shifting them to an 18 h photoperiod. During the 12 h photoperiod, flower opening started shortly before the light period had begun and stopped during the light period, while in the 18 h photoperiod, it proceeded in the middle of the dark period. These results suggested that changes of light to darkness or vice versa were important signals for the start and maintenance of rhythmic flower opening. In addition, we found that even a petal removed from a rose flower showed rhythmic growth when exposed to a 12 h light/12 h dark photoperiod, showing that petals could perceive light and synchronize their growth to the photoperiod.

“…Decreased sucrose conversion to a respirable carbohydrate occurs when there is loss of sucrose synthase and invertase activities (Yamada et al 2007, Kumar et al 2008. The lower vase life response to maltose and galactose is associated with the fact that they are rare types of sugar in flowers (Tab.…”

“…Sucrose is a main component in commercial vase solutions, such as Chrysal (Chrysal, Naarden, The Netherlands), providing a carbon source for flowers and shown to have a positive effect in extending the vase life in cut Dendrobium 'Kao Sanan', 'Lovely Pink' and 'Suree Peach' (Obsuwan et al 2013). In higher plants, the hydrolysis of sucrose provides monosaccharides of glucose and fructose, as was the case in cut Rosa (Yamada et al 2007), which are then further metabolized by acid invertase (β-fructosidase, EC 3.2.1.26) present (in a soluble form) in the vacuoles of the petals (Ap Ree 1974, Kaltaler and Steponkus 1974, Roitsch and Gonzalez 2004. 8-hydroxyquinoline sulphate (HQS) combined with sucrose was found to be very effective in increasing the vase life and reducing respiration rate and physiological weight loss in Dendrobium (Dineshbabu et al 2002) and Gladiolus (Beura et al 2011).…”

A study was conducted to test the effect of 58.5 mM maltose, glucose, fructose, galactose and sucrose, and sucrose concentrations of 14.6, 29.2, 58.5 and 117.0 mM supplemented with 200 mg L -1 8-hydroxyquinoline sulphate (HQS) on the vase life and stem fresh weight changes in waxflower (Chamelaucium Desf.). The effect of the interaction between sucrose and HQS concentrations on the vase life of the cultivar 'Alba' was also investigated. All the types of exogenous sugar significantly increased the vase life of flowers, but decreased the vase life of leaves of waxflower cultivars compared with the deionized water controls, except the leaves of 'Lady Stephanie', 'Purple Pride' and 'Mullering Brook'. The flower vase life of almost all the cultivars treated with sucrose was not significantly different from the life of the cultivars kept in fructose and glucose, except 'Laura Mae Pearl', whose flower vase life in sucrose was significantly lower (9.7%) than in fructose. By contrast, the vase life of flowers of the cultivars treated with sucrose was longer than of those in maltose and galactose. At sucrose concentrations of up to 117.0 mM coupled with 200 mg L -1 HQS, the flower vase life of six out of eight cultivars significantly increased, except in 'Laura Mae Pearl' and 'Mullering Brook', whose flower vase life was maximized at the concentrations of 29.2 and 58.5 mM respectively, while the vase life of their leaves decreased. Sucrose concentrations from 14.6 to 29.2 mM coupled with 50 mg L -1 HQS maximized vase life for both the flowers and leaves of 'Alba'. Cultivars with a longer vase life of flowers maintained stem fresh weight above the initial stem fresh weight longer.

“…Glucose and sucrose fractions from leaves and petals were collected using liquid chromatography (Yamada et al 2007). Collected fractions were dried with rotary evaporator and added to 1 ml of scintisol (Dojindo, Japan); then the amount of radiation was measured for 10 minutes by liquid scintillation counter (LSC-5100, Aloka, Japan).…”

To understand the role that the leaves play in the translocation of soluble carbohydrates in cut rose flowers, we first evaluated the effect of leaf removal on flower quality and the sugar content in petals. Cut rose flowers with leaves had higher soluble sugar content in petals compared with cut flower without leaves. Next, we treated cut flowers with radioactive glucose to clarify translocation routes of exogenously applied sugar. There was no significant difference between the specific radioactivity of sucrose and glucose in leaves, but specific radioactivity of sucrose in petals was much higher than that of glucose. These results suggested that most of the exogenously applied glucose first moved to the leaves, where it was converted into sucrose and then the synthesised sucrose was translocated to the petals. Our results showed that the leaves of cut rose flowers play an important role in the metabolism and transportation of exogenously applied soluble carbohydrates toward the petals, thus contributing to sustaining the post-harvest quality.
