Abstract

The physiological changes of cut tuberose (Poiianthes tuberosa L.) flower spikes in cultivars "Mexican Single" and "Double" as Influenced by different chemical preservatives In vase was studied. Flower spikes were treated with the (T1)-CaCl2-2%, (T2)-Citric acid-400 ppm, (T3)-CoCl2–25 ppm, (T4)-AgNo3–50 ppm, (T6)-STS-300 ppm, (T7)-Sucrose-4% and double distilled water as control. The results showed that control and AgNo3 treatment recorded the maximum fresh weight of spikes whereas, the spikes treated with CaCl2 and STS recorded the minimum fresh weight of spikes. The dry weight reduction was observed to be the highest In control and sucrose treated spikes whereas, the lowest In the spikes treated with AgNo3• At senescence cobalt chloride treated spikes recorded the highest dry weight reduction, water uptake by spikes was observed to be highet in the spikes treated with AgNo3 and the lowest sucrose treated spikes. The vase life of tuberose flower spikes was recorded to be the maximum with sucrose treated and the minimum with CaCl2 treated. The vase life of cv. "Double" was comparatively higher than that of cv. "Mexican Single".
