USING PROBIOTIC BACTERIA TO CREATE A NOVEL ORGANIC FLORAL PRESERVATIVE FOR ROSE
Abstract:
INTRODUCTION One of the main issues in cut flower postharvest is controlling microorganism growth. The importance of clean cutting instruments, buckets, and solutions are stressed in many general postharvest resources (Sacalis and Seals, 1993; Dole and Wilkins, 2005; Hunter, 2000; Armitage et al., 2004). Research has shown that bacterial growth in vase solutions can lead to stem vasculature blockage causing petal and leaf wilt, bent neck, or similar water stress related symptoms that reduce vase life (Put, 1990; Put, 1986; van Doorn et al., 1991; Zagory and Reid, 1986; de Witte and van Doorn, 1988). The effects of bacteria concentrations in vase solutions differ with cut flower species. Put and Jansen (1989) found cut Rosa ‘Sonia’ vase life was reduced by bacteria concentrations as low as 105 cfu·ml-1, while Jones and Hill (1993) found Dianthus caryophyllus ‘Medea’, Iris, Alstroemeria, and Tulipa to be tolerant to bacterial counts up to 108 cfu·ml-1. Therefore, the number of bacteria in the vase solution may not be the primary cause of wilting or shortened vase life in all cut flower species.
