The holding solution containing 5% sucroce + 20 mg l-' AgNO, also significantly increased the vase-life of rose cult ivars 'Eiffel Tower', 'Swartmore' and 'Yankee' but not' King's Ransom' and 'Confidence'. AgNO, slightly reduced ethylene production of 'Christain Dior' flowers held in distilled water. AgNO, greatly reduced ethylene production of flowers in solution containing 1-aminocyclopropane-l.-carboxylic acid (ACC); AgNO, also counteracted the effect of ethylene action induced by ACC. AgNO, greatly reduced microbial population in vase-water and improved water uptake of'Chirstian Dior' flowers. Silver thiousulfate (STS) complex was not as effective as AgNO, for the increase in vase-life of cut roses and the reduction of microbial population. |
