Abstract

This study was carried out to investigate the effect of plug cell size on the seedling growth and to provide a guideline for practical production of spinach (Spinacia oleracea L.) in the summer season. Leaf length reached to 8.7cm at 30 days after seeding in 200 cells plug tray. Plants grown in 288, 406 (A) and 406 (B) had the leaf lengths of 7.3, 5.6 and 7.0cm, respectively. Seedlings grown in 200 cells had larger leaf blades (4.4cm) as compared to those in the other cells. Seedlings grown in 200, 288, 406 (A) and 406 (B) had 7.2, 7.2, 5.4 and 5.4 in number of leaves, respectively. The greatest fresh weight was achieved in seedlings grown in trays of 200 cells, followed by 288 cells, 406 (B) and 406 (A) cells. Dry weight showed a similar trend to fresh weight. Leaf length, leaf blade length, leaf width and fresh weight generally increased as plug cell sizes became larger. From the above results, 288 cell trays are recommended for spinach seedling production based on economic view.

본 연구는 여름철에 시금치를 안정적으로 재배하기 위해 육묘시 플로그 트레이의 셀 크기에 따른 생육 반응을 구명하고자 실시하였다. 시금치 육묘 중 셀 크기에 따른 엽장의 변화는 육묘 후 30일에 200구에서 8.7cm로 역시 가장 길었고, 288구는 7.3cm, 406(B)구는 7.0cm, 406(A)구는 5.6cm로 육묘일수가 증가함에 따라 셀 크기에 비례하여 엽장도 길어지는 경향을 나타내었다. 또한 엽신장의 생육변화도 엽장과 마찬가지로 셀 크기가 클수록 엽신장의 생장율도 촉진되어 200구에서 4.4cm로 가장 길었다. 엽수의 변화는 육묘 후 10일에는 모두 동일하였으나 30일에는 200구와 288구가 7.2매 406(A)구와 406(B)구는 5.4매였다. 셀크기에 따른 지상부 생체중과 건물중은 비슷한 경향을 나타내었으며, 육묘 후 30일에 시금치 묘의 생체중은 200구가 1.3g으로 가장 높게 나타났고, 288구에서 1.1g, 406(B)구는 0.6g, 406(A)구는 0.4g으로 셀 크기가 클수록, 육묘일수가 길어질수록 생체중이 증가하였다. 결과적으로 트레이의 셀 용적이 넓을수록 지상부와 지하부, 그리고 생체중 등의 발달이 좋은 것으로 나타났다. 본 연구에서 200구와 288구 플러그 트레이에서 육묘한 시금치는 생육 30일까지 생육에 큰 차이를 보이지 않아 생산비를 고려해 볼 때 288구 플러그 트레이를 사용하여 재배하는 것이 적당하다고 생각된다.
