Sacred lotus (Nelumbo nucifera Gaertn) ‘Boondarik’ is the cut flower that its demand is
high in round of the year. However, sacred lotus has very short vase-life, only
3-5 days at ambient temperature (29-30˚C).
This research studied effect of ethephon and 1-MCP, ethylene inhibitor, on
vase-life and qualities of scred lotus stored at room temperature (29-30˚íC). In the first
experiment, we dipped lotus flower in 0, 100, 200, and 300 ppm ethyphon to
investigate effect of ethylene on flower senescence. The results
demonstrated that at
day 1, flower obtained 200 and
300 ppm ethephon increased
significantly water uptake
than control and dramatically declined during vase-life.
In the second experiment, we
dipped the lotus in 500 ppm ethephon before fumigating the flower with 0, 200,
400, 600, and 800 nLL-1 1-MCP. The flower was then stored at room temperature (29-30˚C).
The results demonstrated that at
day 3, flower that
obtained 600 nLL-1
had significantly less weight
loss than control. Fumigating
the flower with 600 nl/l
1-MCP was significantly more green than other
treatments. Therefore, it was concluded that ethylene increased water
uptake whereas 600 nLL-1 1-MCP decreased weight loss and delayed
green colour of the petal of lotus stored at room temperature (29-30˚C)
.
