Abstract
The effects of pre-treatment substances on vase life and physiological
character of cut Lilium Oriental hybrid ‘Siberia’ and Lilium Asiatic hybrid ‘Dream
Land’ were studied. When florets of ‘Siberia’ were treated with Promalin
(GA4+7+BA), the vase life was increased as compared to other treatments. The
amount of ethylene produced continuously decreased and respiration rate showed a
climacteric type rise on the 5th day. The sugar contents increased in petal, but
decreased in leaf and ovary. When florets of ‘Dream Land’ were treated with GA4+7
and Promalin, the vase life increased. The amount of ethylene production and
respiration rate showed peak points on the 1st day. Also, the sugar contents showed
the same results as with ‘Siberia’. In the case of ‘Siberia’, vase life was extended with
Dan-solution 2 [(nano particle pure colloidal Ag+
ion) 0.1% + Natural chitosan]
treatment. The amount of ethylene produced continuously decreased and respiration
rate showed a climacteric type rise on the 5th day. But they were not significantly
different between treatments. The sugar contents increased in petal, but decreased in
leaf and ovary. When florets of ‘Dream Land’ were treated with Dan-solution 2, the
vase life was also increased. The amount of ethylene produced and respiration rates
showed peak points on the 1st day. Also, the sugar contents showed the same resul
