Study on Chrysanthemum Vase - Life by Pulsing

Abstract

Study on vase-life of 4 growth stages of chrysanthemum (Chrysanthemum morifolium L.) showed that 50% open stage of flower was the most suitable stage. Distilled water was the most suitable for holding associated with stem cutting and water changing everyday at 25 ?C. From anatomical study indicated that there were the same kinds of tissue in all growth stages of flower stem, and secondary growth was observed. Increase of secondary xylem varied on the age of flowers. Various kinds of solution were used for pulsing flowers at several periods of time. It was concluded that at 30 minutes pulsing with 10% sucrose + 0.03% AgNo3 or 5% sucrose + 0.02% 8 *- HQS or 10% sucrose + 0.3% CuSO4.5H2O gave the good average vase-life 8.7, 9.0 and 10.0 days respectively.
