Abstract

The objective of the experiment was to investigate the effect of two growing areas in the greenhouse on the plant growth characteristics, physiological responses and yield attributes of the 'Cupra' sweet pepper. Two growing areas of the greenhouse were as follows, central part area (CA) and north part area (NA). Daily average temperature of the CA was $1.6^{\circ}C$ higher than those of NA. Plant height, number of internode, and SPAD value in the CA were significantly higher than NA both six weeks and twelve weeks after planting. Net photosynthesis of the sweet pepper leaves of the CA was significantly higher than those of NA. The total fruit yield of the sweet pepper was 20% higher in plants grown for CA than that of NA. These results suggest that air temperature in the greenhouse influenced plant growth characteristics, net photosynthesis and total yield of sweet pepper whether pepper plants were grown as CA or as NA.

본 연구는 착색단고추 재배온실 내의 위치에 따른 온도 환경 차이가 생육에 미치는 영향을 알아보고자 수행하였다. 지상부의 온도는 중앙부가 북측부보다 일평균 온도가 $1.6^{\circ}C$ 정도 높게 측정되었으며, 근권부의 온도도 중앙부에서 $2.2^{\circ}C$ 높았다. 착색단고추의 초장, 절간수, 경경 등은 온실 내 중앙부에서 북측부보다 유의하게 높았다. 정식12주 후 초장은 중앙부에서 153cm/plant로 북측 127.2cm/plant보다 길었으며, 절간수는 2개 더 많았고, 경경 또한 1.5mm/plant 더 두꺼웠다. 또한 순광합성속도도 중앙부에서 북측부보다 높게 나타났다. 수확된 상품과의 수량도 중앙에서 49.1개/5주로 북측의 40.5개/5주에 비해 20% 정도가 증대되었다. 온실내 위치에 따른 온도 환경 차이는 착색단고추의 생육 및 광합성률에 영향을 주어 생산량에 차이를 나타내는 것으로 판단된다.
