“…It is well known that sucrose supply increases the longevity of many cut flowers, since sucrose can act as a source of nutrition for tissues approaching carbohydrate starvation, flower opening and subsequent water relations (Kuiper et al, 1995), similar finding were obtained by Lalonde et al (1999);Nichols (1973); Ichimura (Ichimura, 1998) and Downs (1988).…”

Problem statement: This experiment was carried out in the laboratory of the Department of the Biology, Taif University, Saudi Arabia. Approach: The study was conducted to investigated the silver nitrate (AgNO 3 ) and sucrose at different concentration on rose cut flowers longevity, which determined on the basis of wilting, chlorophyll retention and carbohydrate degradation .The treatments were, water control, 20, 30 or 50 ppm AgNO 3 and sucrose at 1,2or 3% w/v. Results: The results showed, flower vase life was prolonged by all AgNO 3 treatments. The best concentration was 30 ppm .The effect was further improved when AgNO 3 was combined with 3% sucrose, which recorded the best vase life compared to other concentrations of sucrose .The per cent of wilting was minimized as result of using this combined treatment However the per cent of wilting increased with the increase in concentrations of AgNO 3 and complete wilting occurred after 10, 8 and 7 days when treated with 20, 30 and 50 ppm of AgNO 3 , respectively, while sucrose shortened the period to reach wilting. Also AgNO 3 at 30 ppm retarded the chlorophyll as well as carbohydrate degradation during the postharvest life. The experiments were repeated three times with three replicates and a completely randomized design had been used. The experiments extended from February, 2006-September, 2008. The difference between means was performed using Duncan multiple range test at 0.05 levels. Conclusion: A significant improvement in vase life of rose cut flowers was occurred when treated with 30 ppm (AgNO 3 ) more effects when combined with 3% (w/v) sucrose, so we recommended that to use the previous treatments with this concentrations for a long vase life and commercial productions.

“…Application of preservatives may alter the water balance (Le., water retention after uptake, and transpiration) of many cut flowers e.g., Gypsophila (Downs et al 1988), roses (De Stigter 1981, andProtea eximia (paull et al 1980). …”

“…Also, the 5% sucrose solution appeared to be toxic to foliage, which reduced transpiration even further. It has been reported that Chrysanthemum (Gay & Nichols 1977) and Gypsophila (Downs et al 1988) leaves dehydrate when treated with excessive concentrations of sucrose. Pulsed inflorescences had improved water balance as a result of a reduced rate of nett water loss during display (Experimentl, Fig.…”

Display life of Leu cosper mum cv . Firefly is restricted by foliage damage. Treatment with sucrose solutions, either continuously during display (1 % sucrose) or for a 24 h pulse treatment at 20°C (5% sucrose), failed to reduce leaf desiccation. Continuous 5% sucrose treatment induced more severe leaf damage and reduced leaf display life further, whereas flower head display was increased greatly with continuous sucrose treatments. Preservatives improved the water balance (expressed as nett water loss) of inflorescences during display life, but failed to reduce the rapid decline in water uptake that occurred during the first days of display. During continuous treatment, transpiration was reduced, possibly as a result of greater leaf damage in treated inflorescences.

“…Others were only pulse treated with STS (0.5 raM, lhr., 19 °C) and CHI (0.5 lnM, lhr.,19 °C) before their transfer to distilled water. STS was prepared according to Downs et al (1988). Besides the pulse treatment of buds with CHI at 12 AM, pulse treatment was also given to fresh flowers taken out of distilled water at 6 PM.…”

A b s t r a c tSilverthiosulphate which is a potent inhibitor of ethylene action was fntmd to be ineffective in delaying senescence of detached flowers of h-is germanica whereas cycloheximide, a protein synthesis inhibitor, effectively delayed the senescence of these flowers and extended the longevity to 6 days. However, this treatment resulted in suppression of bud opening. When cycloheximkte treatment was given at progressive intervals it became less effective in inhibiting bud opening and delaying senescence. Cycloheximide treatment maintained a higher protein content in the perianlh tissue of flowers cmnpared to untreated flowers.
