Abstract

Abstract Stock plants of Chrysanthemum morifolium Ramat. cv. ‘Bright Golden Anne’ lighted continuously from September 30 to May 15 with Multivapor and Lucalox lamps (100 W/m 2 ) produced more cuttings than those receiving only seasonal daylight and photoperiod lighting. High intensity supplementary lighting improved cutting quality by increased fresh and dry weight and stem diameter. Cuttings from plants receiving high intensity lighting rooted in fewer days, had greater root fresh and dry weights, and greater top fresh weight than plants lighted photoperiodically. After transplanting, the cuttings given high intensity light became established more rapidly and developed into flowering plants of higher quality.
