Pearls®
Petite vase life test
Pearls® Petite is Selecta’s new gypsophila variety with small, semi-double fl owers, concentrated on a dense infl orescence. It has strong and stable stems and terrifi c display volume. This variety is designed for the bouquets market.
Petite, like all others Pearls® varieties, was specially selected for its superior quality and longevity. In or- der to prove this statement, we asked Florcontrol to do their independent vase life test. Below are the results of this test.
Objective: Test the VL, comparing the varieties Pe- tite, Mirabella, Million Stars, and Ginga Way, treating them with STS.
Methodology: After harvesting, the fl owers got a treatment of the solution Chrysal AVB + Citric Acid for two hours. In the second step, all gypsophila varieties were treated with Chrysal FVB + Citrico Acid + Sugar for nine days. Florcontrol received the fl owers from the farm the next day after the second treatment was fi nished. Florcontrol placed the fl owers in dry pack- ing and stored them at 4° C for seven days, simulating in this way the transportation period. After this pro- cess, all bunches in sleeves were moved into pure wa- ter with +/- 1 ppm of chlorine at room temperature. The calcifi cation identifi ed two aspects of evaluation in the vase life: durability, the percentage of fl owers showing some defect during the 10 days of the evalu- ation, and percentage of fl owers dead and alive.
The conditions the evaluation room: 12 hours light/ 12 hour darkness Temperature of the room at day: 20°C (+/- 2°C) Temperature during the night 16°C (+/- 2°C) RH 78%
Final test results: Durability average Mirabella: 8 days Durability average Million Stars: 10 days Durability average Pearls® Ginga Way: 10 days Durability average Pearls® Petite: > 10 days.
Pearls® Petite variety was characterized by fl owers with good opening and dense clusters. In this test the vase life of the Petite was greater than of the other tested varieties (Ginga Way, Mirabella, and Million Stars.) During this evaluation the water in the vases of each product remained clean and the fl owers stems in the water did not show any deterio- ration.
