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’
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.
1. Vase life
4 Treatments x 3 replicates = 12 vases
6 stems per variety = 12 stems/vase
|Treatment||‘Light Orlando’ Rose Vase Life (days)||‘Orange Unique’ Rose Vase Life (days)|
|No Stem Cut—placed in vase with water||7.7 b||7.6 b|
|Stem Cut with floral orange shears— placed in vase with
|7.8 b||8.9 b|
|StemPro— placed in vase with water||9.7 b||10.3 ab|
|StemPro—placed in vase with Floralife® Crystal Clear 16ml/L||12.9 a||12.8 a|

Conclusions: Flowers recut with StemPro and then placed in FloraLife Crystal Clear flower food vase had the best vase life for roses in this experiment.
