Abstract
Cut flowers cultivation and production ranked top in the world. Gladiolus are among the most
popular cut flowers and the floriculture industry's most profitable crop. The main physiological
process that affects the quality of cut flowers is senescence. Gladiolus, which is renowned for
its glitz, perfection, and multicolored spikes, is the most popular cut flower in international
markets. Although citric acid is a common element in many vase solution preparations, its
usage to harvest is a novel strategy for extending the vase life of cut flowers, as previously
reported. The investigation was carried out with gladiolus cv. Red fortunate and White
prosperity to assess the effect of chemical floral preservatives on gladiolus in terms of vase life
and flower quality. The experiment was conducted of two chemical preservatives, citric acid
(T1=100 mg/l, T2=200 mg/l, and T3=300 mg/l) and malic acid (T1=100 mg/l, T2=200 mg/l,
and T3=300 mg/l) in base solution sucrose 3% were used. The results showed that citric acid
gave the maximum vase life by giving the treatment T1 which is 100mg/l. T1 gave maximum
water uptake, increased flower diameter, sustain more fresh weight, and maximum Membrane
stability index than other treatments. Whereas Malic acid gave maximum vase life when the
solution was applied at the rate of 300mg/l by comparing to others treatments.
Keywords: Citric acid, Malic acid, Postharvest life, Membrane stability Index
