착색단고추(Capsicum annuum ‘Jubilee’ and ‘Fiesta’) 추가유인이 생육과 수량에 미치는 영향

본 연구는 착색단고추('Jubilee' 와 'Fiesta') 양액재배 시 생육중기의 추가유인이 생육과 수량에 미치는 영향을 조사하기 위해 수행하였다. 파종과 정식은 2000년 7월 28일과 9월 2일에 하였고, 수확은 2000년 12월 초부터 2001년 7월 초까지 하였다. 추가유인은 22 - 23절에서 되었다. 추가유인처리는 대조구인 2본유인에 비해 품종에 관계없이 초장과 과실크기가 감소하였고 과중은 5g 정도 감소한 반면 상품과수는 주당 5개 정도 증가하였다. 2월과 3월에 추가유인했을 때에는 각각 4월과 5월에 현저하게 수량이 증가하였다. 이러한 생육중기의 추가유인 결과로 후기수량이 25%('Jubilee')와 16%('Fiesta') 증가되어 전체 상품수량에서도 약 11 - 15%의 증가를 보였다. The study was carried out to investigate the effect of training an extra shoot during mid-growth stage on the growth and yield of red (Capsicum annuum 'Jubilee') and yellow (Capsicum annuum 'Fiesta') sweet peppers. Seeds were sown on July 28, seedlings were transplanted on September 2, and fruits were harvested from early December in 2000 to early July in 2001. An extra shoot was trained at the 22nd-23rd node during mid-growth stage in February and March, 2001. Regardless of cultivar, plant height and fruit size decreased by training an extra shoot during mid-growth stage. Fruit weight in this treatment also decreased by about 5 g, while number of marketable fruits increased by about five fruits per plant as compared to those in the control which had only two stems trained per plant. When an extra shoot was trained in February and March, fruit yield increased remarkably starting from April and May. As a result, yield of late fruits increased by 25% in 'Jubilee' and 16% in 'Fiesta', and total marketable yield increased by 11-15% as compared to that of the control. KCI Citation Count: 0
