Most of chrysanthemum growers are using the conventional farming method which is producing plug tray seedlings, after then planting them in the ground. However, as the tendency to excessively spend on operating continues, the number of farms who want to use the direct cultivation method of directly planting cuttings in the soil is increased. It is difficult to achieve successful root establishment after planting due to inexperience of management and treatment methods such as rooting agents and fungicides. In particular, during the high temperature period, the decay rate of cuttings during direct cultivation increases due to the influence of high temperature and humidity in the house. Therefore, in this study, Three cultivars of ‘Yes Ruby’, ‘Perfect’ and ‘Yes Holic’ which are grown for export were used to conduct a study direct-planting as test materials. The purpose of this study was to investigate the effects of cuttings cold storage periods and pretreatment temperature on the reduction of cuttings decay rate and rooting success after direct-planting. Cuttings materials are prepared with a cutting length of 8cm, stored in cold storage at 3±1°C for 3 days, and then treated with a fungicide and rooting compound, then pre-treated with 20°C temperature, 60% or more humidity, 1,000 μmol･m-2･s-1 light intensity). After then, callus formation and rooting status were confirmed at the cut part of the cuttings. In this study, the purpose of this study was to compare with the effect on the rooting state according to cold storage periods (no storage, 1 week, 2 weeks, 3 weeks, and 4 weeks) of cuttings before direct-planting. And we verified the effects of rooting status along with the temperature treatments (no treatment, 15°C, 20°C, 25°C, and 30°C). Regarding the effects on rooting according to the cold storage periods of cuttings, ‘Yes Ruby’ showed the highest superiority over all the treatments at 3 weeks with lengths of roots at 1.71 cm, number of rooting at 28.96, compared to 0.23 cm and 7.33 without cold storage. ‘Perfect’ showed the highest number at 3 weeks with 2.51 cm lengths and 28.38 roots, compared to 2.02 cm and 21.52 without storage. In the case of ‘Yes Holic’, rooting is delayed, so the highest values at 4 weeks with 1.07 cm lengths and 11.72 roots, compared to 0.63 cm and 7.32 without storage. The effect of pretreatment temperature of the cuttings on direct planting was as follows. In the case of direct planting without temperature treatment, all cultivars were not rooted. Compared with this, ‘Yes Ruby’ was the highest root length with 1.68 cm at 25℃, and the number of roots was 51.21 at 20℃, and ‘Perfect’ root length was the highest with 2.18 cm at 25℃, and the number of roots was 26.75 at 20℃. ‘Yes Holic’ root length was highest with 1.84 cm at 25℃, and the number of roots was 18.37 at 15℃.
