Abstract

The objective of this research was to investigate the effects of planting date, root pruning and uprooting on growth, yield and budding ratio of ‘Seolhyang’ strawberry (Fragaria×ananassa Duch.). Planting dates of plantlets with 60 ~ 70 days old were September 7th, September 14th and September 21th. Root pruning rates were controlled to 25% (RP 25) or 50% (RP 50) before transplanting. In the uprooting treatments, the plantlets were pulled out on root media and were replanted into same bed at 10 days (UR 10) and 20 days (UR 20) after transplanting. The delayed planting dates of plantlet resulted in the suppressed growth of plant, reduced yield, and slight earlier appearance of flower buds. The RP 50 treatment showed the lowest value among root pruning treatments in growth and yield, but appearance of flower buds slightly fall behinds. The UR 20 treatment only made flower budding earlier by 6 days than non-treatment. All of root stress treatment was appeared to decrease vegetative growth and yield except the RP 25 treatment. Above results imply that strong root stress was required to emerge second flower bud earlier but which reduced overall growth and yield in ‘Seolhyang’ strawberry.

본 실험은 ‘설향’ 딸기에서 정식날짜와 정식전 단근처 리 및 정식후 굴취처리가 생육, 출뢰율 및 수확량에 미 치는 영향을 조사하였다. 60~70일 묘령의 모종을 9월 7 일, 9월 14일, 9월 21일 정식하였고 단근처리는 전체 뿌 리의 25%, 50%를 각각 잘라내어 무처리와 비교하였다. 굴취처리는 9월 7일 정식한 묘를 10일후 굴취한 다음 재정식한 것과 20일후 굴취하여 재정식한 것을 비교하 였다. 정식일이 늦을수록 지상부 생육이 억제되고 수량 이 감소하였다. 정화방과 액화방 출뢰는 다소 앞당겨지 는 경향이었다. 단근처리와 굴취처리는 지상부 생육이 억제되고 수확량이 감소하는 경향이었고 25% 보다 50% 처리구에서 더욱 확연하게 보였다. 단근처리시 정화방과 액화방 출뢰일은 무처리에 비해 늦추는 경향을 보인 반 면 정식 20일후 굴취처리에서 액화방 분화를 약 7일 정 도 앞당길 수 있었으나 수확량은 무처리에 비해 낮은 결과를 보였다. 따라서 액화방의 분화를 앞당기기 위해 서는 강한 근권부 스트레스가 필요할 것으로 판단되나 수량과 생육을 낮추는 요인으로 작용하므로 재배시 신중 한 판단이 요구된다.
