The effects of nitrogen concentration, shading and nutrient solution concentration, and N/K ratio on growth and macroelements will also be investigated. The effects of 1-MCP on post-storage quality of Aglaonema commutatum Schott. ‘White Tip`, Dieffenbachia seguine (Jacq.) Schott ‘Tropic Marianne`, and Philodendron ‘Imperial Green` will be studied. The post-production quality of Guzmania lingulata and post-storage to Japan would be improved on the basis of the experimental results.貯運乙烯擎天鳳梨粗肋草黛粉葉蔓綠絨simulated transportethyleneGuzmaniaAglaonemaDieffenbachiaPhilodendron
