  • The structure of $(BaSr)TiO_3$ thin film deposited on ITO coated glass, bare glass and (100) Si substrates was not changed, but the crystallinity was improved by the polycrystalline ITO layer and (100) Si substrate. The composition of $(BaSr)TiO_3$ thin film deposited on ITO coated glass was nearly stoichiometric ((Ba+Sr)/Ti=1.08~1.09) and very uniform through all deposition process. But as the deposition temperature increases, the interdiffusion between grown thin film and ITO layer and between ITO layer and base glass is severer. $(BaSr)TiO_3$ thin film deposited on ITO coated glass substrate was highly transparent. The refractive index($n_f$) of $(BaSr)TiO_3$ thin film deposited on ITO coated glass was 2.138~2.286 as a function of substrate temperature.

  • This study was conducted to investigate the optimum concentration and time of BA treatments for the improvement of flowering in Cymbidium encifolium 'Tekkotsusosin'. The flowering rate was increased by the higher concentration of BA treatment, and reached 100% by $400mg{\cdot}L^{-1}$ treatment. But high concentration induced the flower malformation. Therefore, the optimum concentration of BA for increased of flowering rate was about $300mg{\cdot}L^{-1}$. In the time of BA treatment, plants which were treated in June to August by BA $300mg{\cdot}L^{-1}$ were flowered, especially up to 100% in August. However, those treated in April, May, and September did not.

  • This research was conducted to investigate the effect of foliar application of 6-benzylaminopurine (BA), sprayed weeks after pinching (SWP), on ornamental usage of Veronica longifolia L, which is native to Korea. Foliar application of 0, 500, 1,000, and 2,000 mg/L BA on 10 cm long V. longifolia L. plant was evaluated at 0, 7, and 14 days after pinching for growth and flowering. The maximum result of multiple shooting was seen in the 2,000 mg/L BA at 1 week after pinching, and almost all the treatments showed dwarf growth in V. longifolia L. The number of days to flowering was delayed by BA treatments. Moreover, the length and the number of flowers decreased with high concentrations of BA. Thus, foliar application of BA via pinching technique can improve the ornamental usage of V. longifolia L. by controlling the plant type.
