The purpose of this study was to investigate the effects of defoliation treatment on the growth and yield of strawberries. There was a remarkable growth in the above-ground part and root of untreated strawberry plants possibly due to higher amount of photosynthesis, while overall plant growth was su...

딸기란? | 딸기(Fragaria×ananassa Duch.)는 과채류의 저온성 작물로 겨울철 시설재배에서 난방비 부담이 적으며 가격이 안정되어 있어 농가의 고소득 작물 중 하나로 분류되고 있다(RDA, 2015). 또한 비타민 C와 안토시아닌등 항산화 활성이 있는 유용한 페놀 화합물들을 다량 함유하고 있다(Lee et al. | |
일조 부족이 딸기에 미치는 영향은? | 최근 우리나라도 이상기후의 빈도가 증가하고 있으며, 일조시간은 1970년대 2,429시간에서 2000년대에는2,172시간으로 256시간이 감소하였다(Lee and Sim,2011). 겨울철 시설 딸기재배에서 일조 부족은 지상부를 웃자라게 하고 착과가 불량해진다. 이와 아울러 과일의생장지연 및 기형과 발생율이 증가하여 상품성을 저하시키는 요인이 되어왔다(RDA, 2011). | |
실험에 사용된 딸기묘의 대조구는? | 5 mm 되는 것을 사용하였다. 무적엽(엽수 8장)을 대조구로 하였고, 전개된 잎의30% 적엽(엽수 6장)과 50% 적엽(엽수 4장)을 실시하였다. 적엽 처리구는 하위엽을 제거하는 방식으로 관리하였으며 정식 후 7일 간격으로 적엽하여 전 실험기간 동안처리 엽수를 유지하도록 관리하였다. |
