After discussed with major local growers, we initiate this project with objective of acquiring high-quality flowering Phalaenopsis by precise preand post- harvest measures. So far information in relation to flowering quality is limited, and such information is of great importance for local growers to compete with other world-wide Phalaenopsis producers. In this study, we will investigate the optimum growing conditions, especially in mineral nutrition, for flower inducing, in order to ensure a prolonged shelf-life after harvest. Also, we will develop certain postharvest techniques, such as the use of 1- methylcyclopropene (1-MCP), to extend the postharvest life of Phalaenopsis. This project is also aimed to select outstanding Phalaenopsis cultivars, which are less sensitive to ethylene, for future breeding needs.蝴蝶蘭礦物營養1-MCP乙烯花朵壽命Phalaenopsismineral nutrition1-MCPethyleneflower longevity
