Year-round production is feasible with peak export to Japan from Nov to March. However, high temperature and irradiance conditions result in poor cutting and cut flower production. Cool storage of cuttings is considered as a standard procedure for cutting production in US and Europe, while the infornation on optimum cool temperature and/or duration for storage is presently limited. The proposal is to determine the following items in NTU, Chun-Yang, and TAIS: 1.phenotypes' response to cool storage 2.optimum cool storage treatments 3. relationships between carbohydrate changes and rooting performance after cool storage 4. to compare the cuttings growth by plug or bare root.菊花插穗低溫貯藏chrysanthemumcuttingcoole storage
