Abstract

　Fertilization at the third week after flower forcing was the optimum time to obtain better plant height, spike length, flower diameter and flower color on G." Denise". Fertilization at the second week after flower forcing could obtain better plant height, spike length, flower diameter and flower color on G." Cherry". To both varieties of Denise and Cherry, using 250ppm-urea concentration could obtain higher plant height and bigger flower diameter after flower forcing. Flower color development was best a 250ppm-urea for G. "Denise" and 125ppm-urea for G. "Cherry".
