Abstract

The study was aimed to compare yield and fruit quality of red pepper (Capsicum annuum L.) by different harvest frequency and single harvest dates. Red fruit length and width and weight had tendency to decrease with delaying harvest dates, especially fruit weight was lowest at harvest on September. The component ratio of pericarp in the fruit was increased, but seed and calyx ratio of the fruit were decreased as the harvest date was delayed. Total numbers of red fruit harvested per plant had not differences among harvest frequencies, but had significant differences among single harvest dates, especially it was lowest on August 13 than other dates. However, the dry pepper yield by single harvest (one time harvest) was much decreased with compared to several harvest times, harvest frequency could be reduced as less 2 times with delaying harvest date. Redness of fruit was much enhanced at harvest on September 15 or single harvest time than other dates or times, and capsaicin content of red fruit was slightly higher in late harvest dates. Reducing sugar contents of red fruit did not shown differences among harvest times and dates.

본 연구는 노지에서 붉은 고추 수확 횟수와 시기를 달리하여 고추의 수량과 품질을 분석 비교하였다. 시기별로 수확된 붉은 고추의 길이와 폭, 그리고 과중은 수확 초기보다 후기로 갈수록 줄어드는 경향이나, 특히 과중은 9월 19일의 수확에서 가장 낮았다. 그리고 과피의 무게비는 후기로 갈수록 높아졌으나 꼭지나 씨의 무게비는 반대로 감소하였다. 주당 적과수는 수확 횟수 간에는 유의성이 없었으나 일시수확의 시기 간에 현저한 차이를 보였다. 즉 8월 13일에는 주당 10개를 수확하였으나 9월 30일과 10월 19일에서는 주당 28-34개를 수확하였다. 수확횟수 5회에서 2회까지의 건과중으로 보면 수확횟수 단축의 가능성이 있으나 1회의 일시수확은 건과중과 상품과율을 현저히 떨어뜨렸다. 적색소 함량은 9월 중순의 수확한 열매에서 가장 높았고, capsaicin 햠량은 초기보다 후기에 높게 나타났으며 환원당은 수확시기에 따라 일정한 경향을 보이지 않았다. 그리고 1회로 수확한 것은 2-5회 수확한 고추에 비하여 색소의 함량이 높았으나 환원당의 함량은 낮았다.
