Loss of appealing quality characteristics and
rapid desiccation within a short period after detaching from
mother plants is one of the major problems in cut foliages.
Effect of pulsing with benzyl adenine (BA), 8-Hydroxy
Quinoline citrate (8-HQC) and sucrose on vase life of cut
leaves of Asparagus setaceus syn. Plumosus was investigated.
Two durations of pulsing viz., 12 and 24 h were
employed. Pulsing for 12 h with BA (25 ppm) ? 8-HQC
(200 ppm) ? 10 % sucrose resulted in higher fresh weight
at senescence.The lowest physiological loss in weight was
registered by the cut foliages pulsed for 24 h with BA
(25 ppm) ? 8-HQC (200 ppm) ? 10 % sucrose. Pulsing
the cut foliages for 24 h with BA (25 ppm) ? 8-HQC
(200 ppm) ? 10 % sucrose resulted in the maximum
uptake of water and registered the highest water balance.
The lowest transpirational loss of water was found to be
associated with foliages pulsed with 10 % sucrose alone for
24 h. The foliages pulsed with BA (25 ppm) ? 8-HQC
(300 ppm) ? 10 % sucrose for 24 h registered lowest ratio
between water loss and water uptake. Results suggest that
application of 10 % sucrose?BA (25 ppm) ? 8-HQC
(200 ppm) as a pulse treatment for 24 h can be recommended
to prolong the postharvest life (28.50 days)
through delayed leaf senescence and thus enhance the
marketability of cut leaves of Asparagus setaceus syn.
Plumosus.
