Physiological and biochemical changes of cut gerbera inflorescences during vase life.

 

Some physiological and biochemical changes in cut Gerbera jamesoni cv. Red Marleen inflorescences were evaluated during vase life in distilled water and preservative solution (2.5% sucrose + 150 ppm 8-HQS + 200 ppm KCl). Ligula cell membrane permeability measured as electrolyte leakage from ligulas was 1.4 times greater in inflorescences held in distilled water than in those held in preservative solution. Conductivity of the preservative solution diminished during the first day of vase life and then increased. Conductivity of the control (distilled water) increased by 334 micro S on day 7 of vase life compared with that observed on the day 1. The rate of respiration, fresh weight and vase life of inflorescences held in preservative solution were greater than in those held in distilled water. The colour of ligulas intensified during vase life due to an increase in anthocyanin and carotenoid pigment contents. After 5 days the colour intensity was greater in inflorescences held in water than in tho

se held in preservative solution.
