The effects of pre-storage treatments on postharvest quality of anemone (Anemone coronaria) cut flowers
This study was conducted to evaluate the effects of pre-storage treatments on vase life and other flower quality characters of Anemone cut flowers. Flower stems were collected from a commercial orchard. Pre-storage treatments were applied to the flowers. These were consisted of: A) holding stems in water containing 50 ppm silver nitrate plus 30 ppm sucrose; B) spray 50 ppm Gibberellins (GA3) on the flowers, one day before harvest; C) spray 50 ppm GA3 on the flowers after harvest. For treatments B and C, stems were held in the same solution of treatment A. D) apray 1% sucrose on the flowers after harvest; E) spray 1% sucrose on the flowers after harvest + spray 50 ppm Gibberellins on them one day after harvest. For treatment D and E, the stems were held in 50 ppm silver nitrate solution. F) holding the stems in pure water condition; G) holding the stems in normal water. During these experiments, light intensity was 300 Lux, temperature was 16
+2°C and humidity rate was 50%. Variables were included petal abscission rate, leaf yellowing rate, stem bending rate, flower wilting rate, number of marketable flowers, and flowers’ vase life. The data of these experiments were applied in Completely Randomized Design (CRD), using a SAS statistics software program. Means of variables were tested, using
Duncan test (0.05). Results indicted that the best period of storage was 8 days, to have good-quality flowers in aspects of vase life, leaf quality, petal quality and flower marketability. Furthermore, treatments of B and C influenced better preservation of the flowers quality. Lowest rate of the vase life was obtained via application of D, F and G treatments.
