“…Among flowering trees cultivated in Korea, forsythia and hydrangea were first reported to have CMV infection in 1997 and 1972, respectively (Lee et al, 1982;Lee et al, 1997;Lee, 2004). In the case of roses, it was reported that domestically bred and imported varieties cultivated in Korea were infected with viruses such as TRSV, ArMV, and INSV (Roh and Yoo, 2023). This study also revealed that not only roses 'Deep Purple' and 'Pink Beauty' grown in Korea, but also rose 'Natal Briar' used widely in grafting propagation were infected with TRSV and ArMV.…”

“…'Natal Briar' is the most widely used variety as a rootstock worldwide, and is also used as a rootstock for 'Deep Purple' and 'Pink Beauty' bred in Korea (Kim et al, 2020;Kwon, 2023). However, it has been reported that these varieties have been infected with viruses such as TRSV and ArMV (Roh and Yoo, 2023). Therefore, it is necessary to develop methods for producing virus-free plants for these varieties.…”

Background and objective: This study was carried out to examine the effects of antiviral agents on shoot growth and virus elimination during node culture in rose 'Deep Purple', 'Natal Briar' and 'Pink Beauty' infected with TRSV and ArMV.Methods: Three varieties of roses confirmed to be infected with TRSV and ArMV through ImmunoStrip® Tests were node-cultured, and the medium was treated with antiviral agents ribavirin and vidarabine at 0, 10, 20, and 40 mg⋅L-1 . After 60 days of culture, shoot growth and virus infection rates were evaluated.Results: In 'Deep Purple', vidarabine treatment inhibited shoot growth and survival rate more than ribavirin, and had no effect on virus elimination. Treatment of 20 mg⋅L-1 ribavirin was no significant difference in shoot growth and survival rate compared to control, and TRSV and ArMV infection rates were lowered to 25% and 0%, respectively. In 'Natal Briar', treatment of 10-20 mg⋅L-1 ribavirin showed no statistical difference in shoot growth compared to the control, but the infection rates of TRSV and ArMV were 100%. The shoot growth and survival rate were greatly suppressed in treatment of 10 mg⋅L-1 vidarabine, but both TRSV and ArMV infection rates were 50%. In 'Pink Beauty', the higher the treatment concentration of ribavirin and vidarabine, the more the shoot growth was suppressed. Ribavirin had no effect on TRSV elimination, and 20 mg⋅L-1 vidarabine treatment showed that both TRSV and ArMV infection rates were 50%.Conclusion: Depending on the type and concentration of the antiviral agent, the elimination effects of viruses were different for each variety of rose. It was most effective to treat 20 mg⋅L-1 ribavirin in 'Deep Purple', 10 mg⋅L-1 vidarabine in 'Natal Briar', and 20 mg⋅L-1 vidarabine in 'Pink Beauty' in media for TRSV and ArMV elimination.

“…Smart farms, which have recently been introduced, can achieve improvements in productivity and quality by adjusting the cultivation environment and conditions appropriately for crops using automated facilities. However, most of the cut chrysanthemum farms in Korea carry out fertigation based on soil in plastic greenhouse facilities; and there are many conventional farms that manually open and close the roof and side windows, heat insulation and shading curtains (Roh and Yoo, 2018).…”

Background and objective: This study was conducted to compare the cultivation environment, growth of cut flowers, and management performance of conventional farms and smart farms growing the standard cut chrysanthemum, 'Jinba'. Methods: Conventional and smart farms were selected, and facility information, cultivation environment, cut flower growth, and management performance were investigated. Results: The conventional and smart farms were located in Muan, Jeollanam-do, and conventional farming involved cultivating with soil culture in a plastic greenhouse, while the smart farm was cultivating with hydroponics in a plastic greenhouse. The conventional farm did not have sensors for environmental measurement such as light intensity and temperature and pH and EC sensors for fertigation, and all systems, including roof window, side window, thermal screen, and shading curtain, were operated manually. On the other hand, the smart farm was equipped with sensors for measuring the environment and nutrient solution, and was automatically controlled. The day and night mean temperatures, relative humidity, and solar radiation in the facilities of the conventional and the smart farm were managed similarly. But in the floral differentiation stage, the floral differentiation was delayed, as the night temperature of conventional farm was managed as low as 17.7℃ which was lower than smart farm. Accordingly, the harvest of cut flowers by the conventional farm was delayed to 35 days later than that of the smart farm. Also, soil moisture and EC of the conventional farm were unnecessarily kept higher than those of the smart farm in the early growth stage, and then were maintained relatively low during the period after floral differentiation, when a lot of water and nutrients were required. Therefore, growth of cut flower, cut flower length, number of leaves, flower diameter, and weight were poorer in the conventional farm than in the smart farm. In terms of management performance, yield and sales price were 10% and 38% higher for the smart farm than for the conventional farm, respectively. Also, the net income was 2,298 thousand won more for the smart farm than for the conventional farm. Conclusion: It was suggested that the improved growth of cut flowers and high management performance of the smart farm were due to precise environment management for growth by the automatic control and sensor.
