Effect of Pulsing Before Storage on Postharvest Life of Gladiolus

Abstract

Puking of gladiolus spikes with 20% sucrose in combination with 200 ppm 8-HQS of 1000 ppm AgNO3 before storage resulted in greater floret opening and size than those not pulsed. Pulsing of spikes with 20% sucrose in combination with 4mM silver thiosulphate resulted in maximum floret longevity and vase life. A sucrose treatment alone was not effective. However, these three treatments with sucrose were at par and are recommended prior to shipping or storage of gladiolus for long periods.
