ABSTRACT:
The present invention includes a method of extending bloom life of a cut flower. In the method, a storage solution containing 5-deoxy-5-ethylthio-D-ribose (ETR) is provided, and the stem of the cut flower is bathed in the solution. ETR is safe for human use, and is effective at relatively low concentrations. A method for synthesizing 5-deoxy-5-alkylthioribose compounds is also disclosed.
