본 연구는 우량 층층나무 용기묘 생산기술을 개발하기 위하여 5개월간 비닐온실에서 수행되었다. 공시용기로 사용된 플라스틱 망 용기와 일반 플라스틱 용기에서 생육한 묘목의 수고생장 차이는 없었으나, 근원경생장은 플라스틱 망 용기에서 높게 나타났다. 플라스틱 망 용기에서 생육한 묘목은 장근 및 세근발달이 촉진되었으며, 지상부와 지하부 건물생산량이 뚜렷하게 증가하였다. 특히 플라스틱 망 용기에서 생육한 묘목에서는 망 용기에 의해 유도된 공기단근에 의하여 나선형 뿌리가 나타나지 않았다. 본 실험에서 사용된 플라스틱 망 용기는 묘목의 뿌리발달을 좋게하며 지상부 생장이 향상된 층층나무 용기묘 생산에 유용한 것으로 판단된다.

This study was carried out to develop the technique for the production of high quality container seedlings of Comus controversa Hemsley. The seedlings were grown on the medium of peatmoss : perlite : vermiculite (1:1:1, v/v) in plastic net container and no-net plastic container as control for five months in the PE house. The seedlings grown in the plastic net container showed better root collar diameter growth, better development of long and fine roots, more increment of dry mass of roots and shoots than those grown in the no-net container. But the height growth of the seedlings in both container was similar. In particular the seedlings grown in plastic net container had no spiraling roots which were always observed in the control container seedlings. This result was induced by air-root pruning effect from the plastic net container.
