Description Post harvest studies were conducted in Gladiolus (Gladiolus
hortensis L) Cv. White Prosperity to determine the optimum stage of
harvest, duration of wet and dry cold storage conditions, pre- storage
pulsing treatments(sucrose in combination with aluminium sulphate,
GA3 and distilled water) and its effect on simulated transit( 24 hours) and
post harvest life.
Observations were recorded on days taken for the basal floret to
open in storage as well as in vase, vase life, percentage and longevity of
opened florets, floret size, percent gain/loss in fresh weight after
simulated transit and storage, number of opened florets immediately
after storage and total amount of water absorbed per spike.
Among three different stages of harvest of gladiolus spikes, stage
I(when 1-2 florets showed colour ) was found to be superior with
significantly higher vase life (7.10 days) and took maximum number of
days for basal floret to open during storage as well as in vase (2.45 days
and 1.05 days respectively). Among different duration of storage,
gladiolus spikes stored for 3 days in wet cold storage showed
significantly maximum vase life (7.33 days) after simulated transit.
Gladiolus spikes pulsed with sucrose @ 20% + Al2(SO4)3 @ 300ppm
+ GA3 @ 50ppm showed significantly maximum vase life (7.35 days) with
maximum total amount of water absorbed by the spikes (31.75g) after
simulated transit. Among different duration of dry cold storage gladiolus
spikes stored for 3 days showed significantly longer vase life (7.85
days).BCR ratio of 1.77 was observed in treatment consisting of harvest
stage I with 3 days cold storage duration.
