Abstract

This study was conducted to investigate the growth characteristics of cucumber scion and pumpkin rootstock under different levels of light intensity (photosynthetic photon flux, PPF) and plug cell size in a closed transplant production system with artificial lighting. Cucumber scion and pumpkin rootstock seedlings were grown under the combinations of three levels of PPF (PPF 165, 248, and 313µmol·m⁻²·s⁻¹) and five types of plug tray (50, 72, 105, 128, and 200 cells in the tray) for nine days. The shoot dry weight and relative growth rate increased with increasing PPF and plug cell size. As PPF increased, cucumber scion and pumpkin rootstock seedlings had higher dry matter, lower specific leaf area, and lower hypocotyl length. The first true leaf of cucumber scion and pumpkin rootstock unfolded at eight and seven days after sowing, respectively, except the treatment using 200-cell plug tray. The unfolding of first true leaf of seedlings grown in 200-cell plug tray was delayed by one day. Accordingly, it was considered that the use of small cell size such as 200-cell plug tray would require more time for the production of scion and rootstock. Based on the results, we suggest that cucumber scion and pumpkin rootstock be grown in 105-cell to 128-cell plug tray for eight days and 72-cell to 105-cell plug tray for seven days, respectively, when using splice grafting method with root-removed rootstock. Additionally, higher PPF is suggested to improve the growth and quality of scion and rootstock.

균일한 고품질의 접수 및 대목 생산을 목적으로, 인공광형 폐쇄형 육묘시스템 내에서의 접수 및 대목 육묘기술을 개발하고자, 폐쇄형 육묘시스템 내에서의 광량 및 플러그 트레이 규격에 따른 오이 접수 및 호박 대목의 생육을 조사하였다. 광량 3수준 (photosynthetic photon flux, PPF 165, 248, 313µmol·m⁻²·s⁻¹) 및 플러그 트레이셀 규격 5가지(50, 72, 105, 128, 200공)를 조합한 15처리로 9일간 육묘하였다. 오이 접수와 호박 대목의 지상부 건물중은 광량과 플러그 트레이의 셀 크기가 증가할수록 증가하였으며, 상대생장률은 광량과 플러그 트레이의 셀 크기에 따라 두 배 가까운 차이를 보였다. 그와 함께 광량의 증가에 따라 건물률이 증가하고 비엽면적 및 배축장이 감소하여, 묘의 품질이 향상됨을 확인할 수있었다. 제1본엽의 전개는 200공 플러그 트레이에 육묘한 경우를 제외하고 오이 접수의 경우 파종 8일, 호박대목의 경우 파종 7일경부터 이루어졌다. 200공 플러그트레이에 육묘한 경우, 다른 플러그 트레이 규격을 이용한 경우에 비해 생육 및 본엽 전개가 하루 정도 늦어지는 경향을 보였다. 따라서 생육 및 공간이용효율을 고려하였을 때, 단근합접을 위한 오이 접수 및 호박 대목 생산을 위해서는 오이 접수의 경우 105공~128공 플러그트레이를 이용하여 8일 내외, 호박 대목의 경우 72공~105공 플러그 트레이를 이용하여 7일 내외로 육묘하는 것이 추천된다. 아울러 광량 증가에 따라 묘의 생육 및 품질이 향상되므로, 검토된 범위 내에서 가능한 광량을 높여주는 관리가 추천된다.
