Abstract

This study was carried out to investigate the growth characteristics and root development of Mandshurian Linden (Tilia mandshurica Rupr. et Max.) seedlings grown in plastic net container and plain plastic container. The seedlings were grown in the mixture of peatmoss perlite : vermiculite (1:1:1, v/v/v) for five months in the plastic greenhouse. The seedlings grown in plastic net container showed greater root collar diameter growth, better root development, and more increment of root dry mass than those grown in the plain plastic container. In particular, the seedlings grown in plastic net container had no spiraling roots which were always observed in the control . These results suggest that the net container is suitable for container culture of Tilia mandshurica seedlings by enhancing root development. Seedlings grown in the net container and transplanted to various environments showed vigorous rootage and growth.

본 연구는 시설양묘 용기에서 직근성 수종인 찰피나무 유묘의 생육상황 및 뿌리발달 형태를 탐구하기 위하여 5개월 간 플라스틱 온실에서 수행되었다. 공시용기로 사용된 플라스틱 망 용기와 일반 플라스틱 용기에서 생육한 용기묘의 수고생장 차이는 크지 않았으나, 근원경 생장은 플라스틱 망 용기에서 높게 나타났다. 플라스틱 망 용기는 묘목의 뿌리발달에 영향을 끼쳐 묘목의 뿌리발달을 촉진시켰으며, 전체 지하부의 건물생산량을 증가시켰다. 특히 플라스틱 망 용기묘에서는 적극적으로 유도된 공기단근에 의하여 나선형 뿌리가 나타나지 않았다. 따라서 본 실험에 사용된 플라스틱망 용기는 찰피나무 용기묘 생산에 유용하게 활용할 수 있을 것으로 판단되며, 이 용기에서 생산된 묘목은 다양한 식재지 환경에서 식재될 경우 활착율 증가는 물론 생장율 증가도 보일 것으로 생각된다.
