Abstract: Ornamental Daffodils form a prized cut flower class. Silver Thiosulfate Solution (STS) besides some floral preservative solutions were examined for their efficacy to enhance the longevity of daffodil (Narcissus pseudonarcissus cv. Emperor). The spikes were divided into two sets. One set of spikes was pulsed with Silver thiosulfate solution (STS 0.5 mM) for 1 h. Both the pulsed and unpulsed sets of spikes were separately transferred to Distilled Water (DW), Sucrose (SUC 0.15 M), Sucrose (SUC, 0.15 M)+8-Hdroxy Quinoline Sulphate (HQS, 50 mg L-1), Sucrose (SUC, 0.15 M)+8-Hdroxy Quinoline Sulphate (HQS, 50 mg L-1)+Kinetin (Kin, 25 mg L-1). Improved vase life and postharvest performance was observed in all treatment as compared to the control (DW). Pulse treatment of spikes STS (0.5 mM, 1 h) increased solution uptake, maintained high fresh and dry mass of flowers and lowered electrical conductivity of leachates particularly in spikes transferred to SUC+8-HQS. The content of sugars decreased in all treatments. Proteins and phenol content increased, in the pulsed set of spikes; whereas that of α-amino acids followed a contrary pattern. STS (0.5 mM, 1 h) pulse treatment of spikes with transfer to SUC+8-HQS enhanced vase life and improved postharvest performance in this flower system.
