Explanation:
Detailed explanation-1: -For most cut flowers, the ideal range is from 33°F to 35°F. Tropical flowers, however, require 50 to 55°F. Temperatures above the optimum levels reduce vase life and quality. Keeping flowers cool slows down respiration rate and maximizes vase life.
Detailed explanation-2: -This should include a combination of sucrose, citric acid, and biocides, which could provide an effective natural preservative because citric acid and biocides control the growth of microorganisms, whereas sucrose mediates the osmotic potential of the cut flowers by blocking the action of ethylene.
Detailed explanation-3: -1 teaspoon sugar. 1 teaspoon household bleach. 2 teaspoons lemon or lime juice. 1 quart lukewarm water. 01-Mar-2006
