Summary In Hiroshima Prefecture, major cropping type of carnation is planted from the end of June to the beginning of July and flowered from autumn to spring. During 1999-2001, we conducted research into the effect of light reflective film mulching on the yield and quality of cut flowers of 89 spray carnation cultivars in cropping type for early July planting. l . By the use of light reflective film mulching, first-flowers and second-flowers were obtained earlier than untreated control. Therefore the number of cut flowers of second-flowers and total yield were increased, however the effect was depended on cultivars. 2 . The effect of the light reflective film mulching was highly effective for the yield, if the peak of gathering flower of first-flowers was after October. The most of cut flowers quality in second=flowers during the spring was higher than that of first -flowers. 3 . The use of the light reflective film mulching for some varieties was inadequate which first-flowers flowered before October , because the flower quality was poor. 4 . In cropping type planted in early July and harvested by the end of May in the next year, and in the light reflective film mulching culture 'GOLD', 'CHRISTINA PRINCESS', 'PAKIN', 'URARA', 'TOURMALINE', 'BLACKY', 'SAILAR', 'ESTIMADA', 'NAGANO' and 'LAREDO' were the practical varieties m which the number of cut flowers also excellent in the cut flowers quality.
