H
eliconia
the most flourishing cut flower in the tropics owing to its charismatic form and alluringly blended hues of its bracts.
To label post-harvest complications and to protract vase life for a substantial span present experiment was designed employing
antithetical vase solutions of various concentrations and fresh, mature, cut spikes of nine different Heliconia species and varieties.

Biography
Moumita Malakar, INSPIRE Fellow (SRF) of University of Calcutta, India is presently pursuing ‘Doctoral Program’ on Horticulture, specializing in ‘Floriculture &
Landscaping’. The investigation on ‘impact of various vase-solutions on post-harvest life of
Heliconia
inflorescences’ is the worthy portion of my thesis work. She
studied longevity of few ornamental foliages and flowers too but as
Heliconia
presently is highly priced in flower plaza especially in west-Bengal, there arises a
need to extend its vase-life. The positive impact on entrepreneurs of this authentic endeavor is ascertained and will keenly influence the wealth since
Helilconia
is
an emerging ‘specialty cut flower’ in West-Bengal, India.
