Postharvest use of chemical compounds to increase vase life of cut tuberose (Polianthes tuberosa Lin.) flowers.

ABSTRACT :

 

Cut P. tuberosa cv. Chapeada flowers (stems 80 cm long, with 4 pairs of leaves) were held in tap water (control) or in various solutions containing combinations of sucrose (3%), citric acid (200 mg/litre), silver nitrate (600 mg/litre), hydroxyquinoline citrate (HQC, 200 mg/litre), Cycocel [chlormequat] (30 mg/litre) and TIBA (200 mg/litre). Water uptake, FW, DW, wilting, flower abscission and days to flower opening were among the parameters studied. Water uptake was greatest in controls throughout the experiment. FW was greatest in controls and the sucrose + HQC treatment. Significant increases in flower abscission were measured in the sucrose + citric acid and TIBA treatments on days 10 and 12, respectively. Significantly higher numbers of open flowers were recorded in the control than in other treatments on days 4, 6 and 12, but the control treatment also hastened flower senescence.
