The vase life of each cut lily flower was determined by the number of days from the time when the flower was placed in the vase solution until flower had no decorative value (wilting, discoloration, or stem bending). The flower diameter was defined as the maximum width of each flower and measured by a vernier caliper. The hours until full flower opening (HFO) was determined by the number of hours from the time when the flower was placed into the vase solution until the flower diameter reached the maximum value. There was an observation every 6 h at the same time of a day.
