Abstract
Gladiolus is often known as the queen of bulbous crop, falls in Iridaceae family. It is well
known around the globe due to its massive production and well established market. Gladiolus
is mostly used in decorative purposes and for making bouquets. It is highly demanded as cut
flower due to more diversification in its color and species. This experiment was conducted to
assess the potential of different plant growth regulators applying through foliar toward the
vegetative and postharvest life of Gladiolus. Four different concentrations of Gibberellic acid
(T0=0, T1=100mg/l, T2=200mg/l, T3=300mg/l, and T4=400mg/l) and Malic acid (T0=0,
T1=100mg/l, T2=200mg/l, T3=300mg/l, and T4=400mg/l) were used to check its effect on
different growth parameters. The results showed that foliar application of GA @ 100mg/l gave
the maximum plant height, floret per spike, spike length corms weight and diameter. Foliar
application of MA @ 300mg/l gave the maximum chlorophyll content, number of flowers and
Rachis length. The maximum vase life was obtained from T1 and T3 of Gibberellic acid and
Malic acid respectively as compare to all other treatments.
