Effects of Different Planting Locations on the Growth of Four Cultivars of Garden Mum(Dendranthema grandiflorum)

The experiment was carried out to investigate effects of different planting locations on the growth of 4 different cultivars(Kumbangul, Magic Ball, Pretty Ball, and Shinny Ball) of garden mum(Dendranthema grandiflorum) cultivars planted in Cheonan, Jeju, and Pocheon locations, respectively from May to October in 2012. The results of soil analysis showed that soil texture of both Jeju and Cheonan locations was all loamy sands and that of Pocheon was sandy loam. Soil of both Pocheon and Cheonan was weak acid(pH 6.2) and netural(pH 7.8), respectively, whereas the pH of Jeju soil was the lowest 4.9. The lowest content of available phosphorus was showed in Cheonan. Average temperature was 23.17℃ in Jeju where it was the highest among 3 locations whereas Pocheon showed the lowest 19.80℃ during investigated periods. In plant width, ‘Pretty Ball’ and ‘Shinny Ball’ planted respectively in Jeju and Pocheon, showed the optimum value but two other cultivars have no distinct relation with planting locations. Regardless of cultivars, number of flowers and weight of all cultivars planted in Jeju than any other location showed the highest values. Overall results showed that quantitive characteristics of ‘Kumbangul’ was superior to other cultivars and cultivars planted in Jeju were better than other culivars based on planting locations.
