Data in Table (8) illustrated that the most successful treatment was nano silver at 15 mg/l as it achieved the maximum values of carbohydrate content in the spadix and spathe (34.63-29.96 mg/g). On the other side, placing flower in distilled water gave the lowest values in this trait (13.14-12.56 mg/g). This result was consistent with the observation of Van Doorn (2004) who found that petal carbohydrate contents are one of the most crucial factors influencing the postharvest life of cut flowers. It is proposed that there is a positive correlation between the levels of endogenous sugars and the time to petal wilting. In addition, the senescence process of cut flowers is regulated by phytohormones and correlated with the carbohydrate status of the petals.
