Effect of chemicals on longevity of cut Dutch iris.

Studies on the effect of various chemical, separately and in combination with sucrose, on postharvest physiology of cut spikes of iris (Iris hollandica) cv. Prof. Blaaw were conducted during 1997-98, in Srinagar, Jammu and Kashmir, India. Treatments comprised of aluminium sulfate (AS) at 200 and 300 ppm, cobaltous chloride (CC) at 200 and 300 ppm, citric acid at 1000 and 2000 ppm, and sucrose (Su) at 2 and 4% concentrations. Combination of Su and metal salts increased the vase life of cut iris spikes from 9.77 days in the control to 12.66 days in 4% Su + 200 ppm CC, and 12.33 days in 2% Su + 200 ppm CC, 4% Su + 200 ppm AS and 2% Su + 200 ppm AS combinations. Water uptake was noticed maximum in spikes pulsed with CC alone or in combination with Su, and minimum in AS alone or in combination with Su. Water loss was highest (17.66 g/spike) in the control and lowest in 2% Su + 300 ppm AS and 4% Su + 300 ppm AS, recording 10.83 and 10.50 g/spike, respectively. Water balance, fresh weight gain and floret size were observed maximum with CC or As in combination with Su.
