The effects of 
-aminoisobutyric
acid (AIB), aminooxyacetic acid (AOA) and sucrose on the vase life of hybrid Limonium
cv. Blue fantasia 100 were investigated. The flowering branches, each with five
subspikes, were cut from the inflorescence and the cut ends were put in the
solutions to be tested for 24 h, and thereafter in water. Sucrose at a
concentration of 
5 g
l-1 promoted bud opening. AIB at a concentration of 5
mM extended floret longevity. AOA had little effect on vase life. Treatment
with 10 mM AIB in combination with 20 g l-1 sucrose for 24 h
promoted floret opening and inhibited floret senescence. Concentrations of
glucose, fructose and sucrose in florets of branches treated with AIB and
sucrose were higher than those in the control florets. Ethylene production of
AIB-treated florets was less than that of control florets. These results
suggest that promotion of floret opening and extension of longevity by sucrose
and AIB are due to increases in the concentration of sugars in tissue and
inhibition of ethylene production. A pulse treatment with AIB in combination
with sucrose was also effective in improving the vase life of cut whole
inflorescences in hybrid Limonium.
