VASE LIFE OF TORCH GINGER (ETLINGERA ELATIOR) INFLORESCENCES AS INFLUENCED BY HARVEST MATURITY AND 1-METHYLCYCLOPROPENE

E.R.V. Bayogan, M.B.B. Gratuito
Separate experiments determined the vase life and some postharvest characteristics of torch ginger inflorescences as influenced by harvest maturity stage (25, 50, 75, and 100% ) and 1-methylcyclopropene (0, 100, 500, 1000 nl L-1 for 6 h). The various stages can each be characterized by the number of layers of involucral bracts, flexing of involucral bracts, appearance of cone (floral bracts), presence of true florets and days to reach the stage. The vase life of torch ginger inflorescences was terminated when involucral and floral bract browning, wilting and reduced visual quality became distinct; and when true florets senesced. Vase life was longest at 75% and shortest at 25 and 100% opened stages. Water uptake was highest in fully opened torch gingers. 1-Methylcyclopropene did not prolong vase life but tended to hasten the appearance of the true florets.
