Influence of various pulsing chemicals on anthocyanin content, tannin, pH and conductivity of rose cv. Happiness

Different pulsing chemicals significantly influenced tannin, anthocyanin, pH and conducivity of cut roses. In general, there was a slow increase in pH and conductivity, whereas its constant increment was observed in control flowers. At different periodical intervals, maximum enhancement in tannin content was noticed in flowers treated with NAA solution, whereas it was minimum with AgNO₃ pulsed flowers. Upto third day anthocyanin increased and maximum increase was found in AgNO₃ pulsed flowers. Minimum loss in anthocyanin content on sixth day and at senescence was also noticed with AgNO₃ treatment.
