Thus the vase life of the flowers was about 10 days in this experiment. Previously Nukui et al. (2004)
reported that the vase life of ‘LPB’ flowers varied with the flower
samples harvested at different seasons, and the vase life of the
flowers harvested in winter season (December – March) tended
to be longer than that of those harvested in summer season (late
May – September). Regardless of the difference in the time of
harvest, however, ‘LPB’ flowers always produced ethylene in a
climacteric manner and in similar amounts during natural
senescence. In the present investigation, we observed the
variation in the time of maximum ethylene production (varied
from 5 to 9 days) and the length of vase life (varied from 6 to 10
days) in three separate experiments.
