초록

본 실험은 분식물의 삽목번식시 배지에 첨가한 규산질 비료가 분식물의 발근과 생육에 미치는 영향을 조사하 였다. 칼란코에 ‘Kaluna’와 ‘Taos’ 품종은 50구 트레이 에 번식하였고 카네이션 ‘Kazan’과 ‘Tula’ 품종은 128구 트레이에 삽목하였다. 규산질 비료를 상업배지(토실이 상토, 신안그로)와 펄라이트를 5 : 1(v/v)로 섞어 배지 1L당 규산질 비료[MgCa(SiO3)2]를 0, 40, 80, 120, 또는 160g을 첨가하여 발근한 후 정식하였다. 두 작물 모두 배지 1L당 규산질 비료를 40g 첨가한 처리구에서 초장, 엽두께, 뿌리의 생체중과 건물중이 가장 높았다. 하지만 두 작물 모두 규산질 비료의 농도가 높아질수록 초장이 억제되었다. 주사전자현미경(SEM) 촬영을 통한 식물 조직 관찰 결과 규산질 비료를 첨가해주었을 경우 뿌 리와 잎의 조직이 더 조밀해졌다.

This experiment was carried out to examine the effect of a silicate fertilizer on the growth and development of potted plants. Cutting of Kalanchoe blossfeldiana ‘Kaluna’ and ‘Taos’, and Dianthus caryophyllus L. ‘Kazan’ and ‘Tula’ were grown in 50 and 128-cell plug trays, respectively. Rooted cuttings transplanted to the mixture of a commercial medium and perlite (5:1, v/v) supplemented with a silicate fertilizer at 0, 40, 80, 120 or 160 g·L-1 medium was evaluated. A silicate fertilizer supplementation at 40 g·L-1 medium resulted in the greatest plant height, leaf thickness, and root fresh and dry weights in both kalanchoe and carnation. However, plant height was suppressed in the treatment of a silicate fertilizer supplementation at higher concentrations in both kalanchoe and carnation. According to the scanning electron microscope images of transversal sections of tissues of roots and leaves in kalanchoe and carnation, the treatment of a silicate fertilizer supplementation at 40 g·L-1 medium resulted in plants with more compact tissue than the control.
