This study was carried out to examine the effects of cutting condition on the rooting and their subsequent growth of cut flower in plug cutting of summer-flowering chrysanthemum "Iwanohakusen". The more leaves were attached to the cutting, the higher shoot growth and rooting were. Shoot growth of cuttings was not affected by cutting length, but rooting was better in over 5 ㎝ long cutting. Shoot growth was enhanced by increasing thickness of cutting, and 5.5 ㎜ thick cutting was favored in rooting. When the many leaves were attached on the cutting, the length and weight of cut flower increased. Over 7 ㎝ long cutting showed higher values in growth of cut flower and ray flower number. Cutting of 5.5 ㎜ diameter showed more favorable growth of cut flower than the other treatments. Therefore, it is concluded that rooting of cutting and consecutive growth of cut flower was improved when 7 ㎝ long and 5.5 ㎜ diameter cutting with 4 leaves was used in plug cutting of chrysanthemum "Iwanohakusen".
