Abstract

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 ㎎/L BA on 10 ㎝ 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 ㎎/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.
