This study was conducted to determine the effect of growth regulators, genotype, and cutting position on the rooting and root growth from cutting of Chrysanthemum zawadskii H.. Rooting rate of Keungugeolcho in the treatement of IBA 500 and 1000 ppm was the better than those of other treatments of IAA, NAA and Rooton. Rooting rate differed depending on the genotype. Hangryobonggugeolcho was better than Keungucheolcho in rooting rate. The treatment of rooton remarkably induced many roots from the cuttings of eight accessions of Chrysanthemum zawadskii H.. Also, rooting rate and number of root differed depending on cutting position. When cuttings including shoot tip were cultured on tray containing bed soil, rooting rate and number of root induced from cuttings with shoot tip was higher than when cuttings without shoot tip and with lateral axillary bud were cultured.

The stability of carotenoid pigments extracted from Chrysanthemum petals against pH, sugar, and organic acid was investigated. The contents of total carotenoids in C. boreale and C. morifolium were 3.37mg% and 4.56mg% Per fresh weight, respectively. The elect of pH on the stability of extracted carotenoids showed that the periods reaching 50% of pigment retention were more than 5 to 6 days in pH 4, and the longer periods in pH 6 to 7 in both samples. The addition of sugars such as sucrose, sorbitol, glucose and fructose resulted in the reduction in pigment stability of C. boreale, but C. morifolium was contrast to C. boreale. However, citric acid and ascorbic acid were found to have a protective effect on both carotenoid samples extracted from C. boreale and C. morifolium.
