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 tre...

유인 방법의 단점은 무엇인가? | 국내에서 일반적으로 사용되는 방법인 유인 방법은 10월 하순에 채취한 런너를 삽목 및 휴면시킨 후, 이듬해 3-4월 경에 모주로 정식하여 9월에 정식할 자묘를 생산하는 방법이다(Park 등, 2016). 유인 방법은 런너에서 발생한 초기 자묘가 완전한 자가 독립 영양체로 성장할 때까지 모주로부터 수분 및 양분을 공급받기 때문에 안정적으로 자묘를 생산할 수 있다는 장점이 있지만, 11개월 이상의 긴 육묘기간과 높은 재식 밀도에 따른 자묘의 도장, 런너의 발생 시기 및 유인 일자의 차이에 의한 불균일한 묘소질 등의 단점이 있다(Kang 등, 2019; Liu 등, 2019; Zheng 등, 2019). | |
딸기란? | 딸기(Fragaria × ananassa Duch.)는 동절기에 수확되는 대표적인 시설원예 작물로 6,421ha의 생산면적을 가지고 있으며, 맛과 향이 좋고 비타민 C와 항산화 물질을 다량 함유한 영양학적으로 우수한 과채류 작물이다(Bae 등, 2019; KOSIS, 2019). 국내 딸기는 대부분의 농가에서 자가 육묘로 묘를 생산하고 있으며, 종자의 낮은 발아율과 품종 유지의 어려움과 같은 이유로 종자 번식이 아닌 영양 번식을 이용한 육묘를 하고 있다(Jurik, 1985; Rugienius와 Stanys, 2001; Park 등, 2016). | |
국내에서 일반적으로 사용되는 딸기 영양 번식 방법은 무엇인가? | 딸기의 영양 번식 방법에는 유인과 삽목 등의 방법들이 보급되어 왔다. 국내에서 일반적으로 사용되는 방법인 유인 방법은 10월 하순에 채취한 런너를 삽목 및 휴면시킨 후, 이듬해 3-4월 경에 모주로 정식하여 9월에 정식할 자묘를 생산하는 방법이다(Park 등, 2016). 유인 방법은 런너에서 발생한 초기 자묘가 완전한 자가 독립 영양체로 성장할 때까지 모주로부터 수분 및 양분을 공급받기 때문에 안정적으로 자묘를 생산할 수 있다는 장점이 있지만, 11개월 이상의 긴 육묘기간과 높은 재식 밀도에 따른 자묘의 도장, 런너의 발생 시기 및 유인 일자의 차이에 의한 불균일한 묘소질 등의 단점이 있다(Kang 등, 2019; Liu 등, 2019; Zheng 등, 2019). |
