Abstract
Placing “Fire Flash” heliconia (Heliconia densiflora Verlot.) flowers in vase with“ Diplomat” and “Saphire” rose (Rosa hybrida L. ) flowers reduced water uptake (from 7.17 and 7.43 ml/stem/ day to 3.93 and 4.77 ml/stem/day, respectively) and vase life (from 4.5 and 5.3 days to 3.8 and 4.5 days, respectively) of the roses. Wilting of petals and stem bending are also affected. The effects of the heliconia were overcome by adding 0.2% calcium chloride (CaCl2) and/or 200 ppm 8-hydroxyquinoline sulfate (8-HQS) and 5.0% sucrose to the vase solution. “Diplomat” and “Saphire” roses placed in 8-HQS, CaCl2 and sucrose had water uptake 9.23 and 9.93 ml/stem/day and had vase life 6.5 and 8.3 days, respectively. When placed with heliconia, water uptake were 7.60 and 8.80 ml/stem/day and vase life were 6.3 and 7.3 days, respectively. Chemicals also decreased wilting and stem bending of rose flowers.
