The Role of Nitrogen Absorption and Utilization in Maintaining Lower Leaves of Chrysanthemum Morifolium, Ram. 'Cv. Mountain Peak' Under Low Light Conditions

Three experiments were conducted to investigate the influence of potting media and/or nitrogen source on lower leaf yellowing and shelflife of Chrysanthemum morifolium, Ram, 'cv. Mountain Peak' under low light intensity environment. Various growth, quality, and N nutritional measurements were taken at the end of production period and throughout the simulated home environment. In comparison to the other N sources, nitrate was the superior N source for the production of chrysanthemum when vegetative growth, flower quality, and shelflife are evaluated in total. With nitrate fertilization, chrysanthemum plants produced in winter had longer shelflife in soilless than soil mix medium, while no difference was found between either potting mix for summer production.
