Abstract
This study was conducted to investigate the effect of alcohols viz ethanol methanol and nbutanol at different concentrations not only on the vase life of Calendula officinalis L cut flowers but also to record changes in metabolites like starch content and amount of sugars and activities of αamylase and antioxidant enzymes like peroxidase and superoxide dismutase as well as lipid peroxidation Ethanol as holding solution significantly increased the vase life as compared to other treatments or the control nButanol shortened vase life and caused the flower stem to fold whereas ethanol and methanol individually delayed drying up and petals dried slowly from their tips Significant increments in solution uptake moisture content and flower diameter were noticed with 2 ethanol followed by 2 methanol Cut scapes having 2 ethanol exhibited maximum amount of starch and considerably lower amount of reducing and nonreducing sugars This treatment not only brings down the specific activities of αamylase and peroxidase but also decreases the process of lipid peroxidation Effectiveness of methanol 2 is evident just after ethanol application 2 Lowest concentrations of ethanol and methanol also show relatively higher level of SOD activity in cut flowers of Calendula officinalis
