Abstract

This study was conducted to determine the optimum medium and humidification period for the strawberry (Fragaria × ananassa Duch. cv. Maehyang) cutting seedling production. The cuttings were planted in coir (CO), rockwool (RW), phenolic foam (PF), and organic foam medium (OFM) with fogging treatment in 0, 3, 6, 9, or 12 days on February, 2019. And, as the field verification examination research, cuttings were planted in CO, RW, PF, and OFM, with misting treatment in 0, 6, 9, 12, or 15 days on June, 2019. In fogging treatments, rooting and survival rates of seedlings tended to increase with longer fogging periods, and rooting and survival rates were showed significantly higher in CO medium with more than 9 days of fogging periods. In misting treatments, rooting rate was significantly higher in CO and RW medium with more than 9 days of misting periods, and survival rate was significantly higher with more than 12 days of misting periods. There was no significantly difference by growth medium and humidification period in shoot and root growth. Therefore, when considering the rooting and survival rate the CO medium with 9 days of humidification period could be beneficial for the production of the 'Maehyang' strawberry cutting seedlings.

본 연구는 시설 딸기(Fragaria × ananassa Duch. cv. Maehyang)의 삽목묘 생산을 위해 적절한 배지 및 가습 기간을 구명하기 위해 수행되었다. 2019년 2월에 코이어(CO), 암면(RW), 페놀폼(PF), 유기성형배지(OFM)에 삽수를 삽목하여 0, 3, 6, 9, 12일간 포깅 처리를 하였으며, 2019년 6월에 현장실증 실험으로 코이어(CO), 암면(RW), 페놀폼(PF), 유기성형배지(OFM)에 삽수를 삽목하여 0, 6, 9, 12, 15일간 미스팅 처리를 하였다. 포깅 처리에서 삽목묘의 발근율과 생존율은 포깅 기간이 길어질수록 증가하는 경향을 보였으며, CO 배지에서 9일 이상 포깅 처리하였을 때 발근율과 생존율이 유의적으로 높았다. 미스팅 처리에서 발근율은 CO와 RW 배지에서 9일 이상 미스팅 처리하였을 때, 생존율은 12일 이상 미스팅 처리하였을 때 유의적으로 높았다. 육묘기에 배지 및 가습 처리에 따른 지상부와 지하부의 생육은 유의적인 차이가 없었다. 따라서 발근율과 생존율을 고려하였을 때, CO 배지에서 9일간 가습 처리하는 것이 안정적인 삽목묘의 생산에 유리할 것으로 판단된다.
