Abstract

After flowers are cut-off, they start aging quickly. In order to slow down this process and extend the life of a cut flower, postharvest treatment is necessary. This study focuses on identifying the compound(s), which preserves the freshness of a cut flower longest. Fifteen different compounds were tested on the two groups of species; Hybrid Tea and Floribunda from South and North garden. The number of days of freshness for each compound from each garden and specie were measured and these measurements were used to conclude on the compound(s) that preserve the cut roses longest. In terms of analysis; Analysis of Variance, Generalized Estimating Equation and Generalized Linear Mixed Model were used, all of which provided similar results. It was concluded from the fifteen tested compounds that compound6 (Essence of Epiphaneia) and compound12 (Oil of Johns Son) prolong the freshness of cut roses longest. It also appeared that if a rose is taken from southern garden and is of Hybrid Tea specie, the freshness is preserved longer than if it is of Floribunda specie and taken from north garden. Due to the genetic similarity, it is assumed that these results are also applicable to black tulip.
