Growth Characteristics of Landscaping Trees by Container Size in Production of Standard Size

다국어 초록 (Multilingual Abstract)

The purpose of this study was to evaluate the effects of container size on growth of Zelkova serrata, Acer palmatum, Crataegus pinnatifida, Pinus densiflora, Chionanthus retusus, Ilex serrata, Viburnum erosum, and Hibiscus syriacus in container. This study used 22 L, 38 L, and 52 L container and measured seedling height, root collar diameter, seeding quality index (SQI), biomass. Acer palmatum, Pinus densiflora and Ilex serrata were high in 22, Crataegus pinnatifida in 38 L, and Zelkova serrata, Chionanthus retusus, Viburnum erosum, and Hibiscus syriacus in 52 L regarding the relative growth of height and root diameter in statistical significance. The H/D ratio was fine for Zelkova serrata, Pinus densiflora, Chionanthus retusus, Ilex serrata at 22 L, Acer palmatum and Crataegus pinnatifida for 38 L, and Viburnum erosum and Hibiscus syriacus for 52 L. Seeding Weight of Acer palmatum, Pinus densiflora was heavy at 22 L. Chionanthus retusus, Ilex serrata, Viburnum erosum, Hibiscus syriacus were heavy at 38 L, Zelkova serrata, and Crataegus pinnatifida were heavy at 52 L. Zelkova serrata, Crataegus pinnatifida, Pinus densiflora, and Ilex serrata were fine at 22 L, Acer palmatum, Chionanthus retusus, Viburnum erosum at 38 L, Hibiscus syriacus at 52 L about T/R ratio. For SQI, Acer palmatum, and Pinus densiflora were high in 22 L, Chionanthus retusus, Ilex serrata, and Viburnum erosum in 38 L, Zelkova serrata, Crataegus pinnatifida, and Hibiscus syriacus in 52 L. Seedling quality was considered to be appropriate when the growth was balanced between the above and below ground. As a result, it is effective to cultivate Acer palmatum and Pinus densiflora at 22 L, Chionanthus retusus, Ilex serrata, and Viburnum erosum at 38 L, and Zelkova serrata, Crataegus pinnatifida, and Hibiscus syriacus at 52 L.
