Abstract

This study was conducted to examine the effects of plug tray cell size and growth media on good seedling production of Gerbera hybrida Hort. Seedlings were grown for 60 days in 50, 72, 128, 162 cell trays contanning perlite, cocopeat and perlite+cocopeat(1:1, v/v). Perlite showed higher bulk density than cocopeat and perlite+cocopeat. Total porosity was greater in perlite, cocopeat and perlite+cocopeat in order. Cocopeat showed the highest water holding capacity. Number of leaves were greatest in 128 cell tray containing cocopeat. Leaf area was greatest in 50 cell tray containing cocopeat. Seedling growth was also better in plug tray of bigger cell size. Seedling growth of fresh and dry weight of shoot and root was much better in the growth media of perlite+cocopeat.

양액재배용 거어베라 우량묘를 생산하기 위한 기초연구로 플러그셀 크기 및 용토가 묘생장에 미치는 영향을 조사하였다. 용토의 물리성을 측정한 결과 가비중, 진비중 및 공극율은 퍼얼라이트에서 가장 높게 나타났으며 수분보유량은 코코피트에서 가장 높게 측정되었다. 162, 128, 72, 50구 플러그셀트레리별로 퍼얼라이트 코코피트 그리고 퍼얼라이트+코코피트(1:1)을 채우고 60일간 육묘하여 묘의 생육을 조사하였다. 묘의 엽수는 128구 코코피트 처리에서 가장 많았으며 엽면적은 50구 코코피트 처리에서 높게 나타났다. 신초와 뿌리의 생체중 및 건물중 그리고 엽록소 함량은 퍼얼라이트+코코피트 처리에서 높게 측정되었다. 플러그 셀 크기가 클수록 유묘 생장에 효과적이었으며 퍼얼라이트 단용 보다는 코코피트와의 혼용 용토에서 유묘 생육이 가장 양호하였다.
