고품질의 공정묘를 생산하기 위해 접목 및 활착 이후 순화는 출하 전의 묘소질을 감소시키지 않는 중요한 육묘단계이다. 적절한 순화 조건은 2차 육묘시기 전 묘소질을 증가시킬 수 있을 뿐만 아니라 묘의 생육촉진에 효과적이다. 따라서 본 연구는 공정묘의 순화시 적절한 차광조건을 확인하기 위해 수행되었다. 실험 작물은 토마토와 고추를 이용하였으며, 두 작물 모두 활착이 끝난 뒤 벤로형 유리온실에 있는 베드에 터널을 설치하여 차광 처리를 하였다. 차광률은 35%, 55%, 75% 그리고 95%로 진행했고, 차광기간을 1주와 2주로 진행하였으며, 무처리를 대조구로 하였다. 토마토 접목묘의 경우 차광기간 1주, 차광률 55%에서 초장, 경경, 지하부의 건물중, 엽면적이 유의성 있게 우수하였다. 고추 접목묘는 초장, 경경, 엽면적은 차광기간 2주, 차광률 35%에서 가장 높았으나 묘소질을 판단하는 지표인 지하부의 건물중, 충실도, T/R율은 차광기간 1주, 차광률 55%에 비해 낮게 나타났다. 따라서 묘소질을 고려하였을 때, 토마토와 고추 접목묘의 순화시 차광기간 1주, 차광률 55% 처리를 하는 것이 묘소질이 우수한 묘를 생산하는데 적합한 것으로 판단된다.
Acclimatization after grafting and graft-take that in order to produce plug seedlings of high-quality are important plug seedling stage which not reduce the plug seedlings quality before shipment. Appropriate acclimatization environment can not only increase seedling quality before secondary growth ...
