Abstract
This study was aimed to establish the most effective approach for the cultivation of Veronica rotunda var. subintegra (Nakai) T.Yamaz. plants, which was expected as new ornamental plants. We conducted an experiment using plug seedlings, varied the seeding container type and seeding rate. We also varied seedling quality, planting container, soil type, and shading ratio. Seedling quality was used seedlings produced from different seeding containers and seeding rates. The seedling quality were seeding growth using 162, 200, and 288 trays, and seedings rate was used seedlings produced by sowing 1, 2, 4 and 6 seeds. As a result, 162 trays of seedlings were suitable for use in this study. Plants grown with one seed per cell in individual cells exhibited increased individual growth, but those grown with four seeds per cell exhibited better growth for the whole plant. According to seedling quality, seedlings produced in the 162 trays or with four seeds per cell showed higher growth than other seedlings. In the cultivation of V. rotunda var. subintegra (Nakai) T.Yamaz., seedling growth increased depending on container capacity for both shoot and root parts. Container material had no significant impact on seedling growth. Seedlings grew the best on horticultural substrate, and showed better growth on mixed soils with high decomposed granite content than on peatmoss.
