Confidential Experimental Report

TITLE: Testing the StemPro Pneumatic Stem Cutter’s effect on the vase life of roses

DATE of Experiment: 12/13/2013

Researcher: Anil Ranwala & Christy Carter

Experiment #: 045W1314

PURPOSE: Testing the StemPro Pneumatic Stem Cutter’s effect on vase life of roses as compared to using other stem cutting techniques.

CROPS: Two cultivars of roses from Colombia: ‘Light Orlando’ & ‘Orange Unique’

TREATMENTS:

1) No Stem Cut—placed in vase with water
2) Stem Cut (1/2 inch) with floral orange shears—placed in vase with water
3) Stem Cut (1/2 inch) with StemPro Cutter—placed in vase with water
4) Stem Cut (1/2 inch) with StemPro Cutter—placed in vase with Floralife® Crystal Clear 16ml/L

METHOD: Flowers were obtained from Continental Farms. Flowers were unpacked upon arrival.
Stems that were cut per protocol were re-cut in air. Rose heads were dipped in Rovral (20ml/3.785L) to
inhibit Botrytis. Flowers were placed in vases (1L). The vases were kept in an evaluation room with 12
hours of light & 12 hours of darkness with a temperature between 64-68?F.

DATA:
1. Vase life
2. Photos

4 Treatments x 3 replicates = 12 vases
6 stems per variety = 12 stems/vase
