착색단고추 비닐하우스 토경재배시 품종별 온도조건에 따른 열과 발생원인을 구명코자 하였다 열과발생률은 품종간에는 Fiesta가 Jubilee보다 높았고 온도처리간에는 34℃ 고온구에서 높았다. 그리고 환경조건이 좋아지는 4월 이후에 급격히 증가하였다. 과육특성 조사결과 Fiesta품종과 고온처리구에서 과육경도와 건물률이 낮았으나 과육두께는 경향이 일정치 않았다. 과육의 무기성분 함량은 품종간, 온도처리간에 차이가 없었다. 수확시 뿌리상태는 Fiesta품종이 Jubilee보다 좋았고, 온도처리간에는 차이가 없었다. 이상의 결과로 과육의 경도, 건물률, 치밀도 및 뿌리상태 등이 열과발생에 직접적인 영향을 미치고 과육두께나 과육의 무기성분 함량등은 열과발생과 상관이 없는 것으로 나타났다.

This experiment was conducted to investigate the effect of daytime temperature on fruit crack-ing in the paprika cv. Fiesta and cv. Jubilee under soil culture experiment of vinyl house for two years from 2003 to 2004. The rate of cracked fruit was higher in cv. Fiesta than cv. Jubilee and was the highest at the high daytime temperature of 34±1℃. and then rapidly increased after April becomes better weather conditions. The flesh hardness and the rate of flesh dry weight were lower in cv. Fiesta than cv. Jubilee and were the lowest at the high daytime temperature of 34±1℃. but the thickness of flesh was thicker in cv. Fiesta than cv. Jubilee and was the thinnest at the high daytime temperature of 34±1℃. Inorganic matter contents of flesh was observed no difference to the cultivars and also the temperature treatments. Root condition in harvesting time was better in cv. Fiesta than cv. Jubilee and was not difference in temperature treatments. Therefore, the rate of cracked fruit showed up a positive correlation to the flesh hardness, flesh dry weight, flesh firmness and root condition, and has not correlation to the flesh thickness and inorganic matter con-tents. In conclusion, differences in cultivar sensitivity and the highest rate of cracked fruit in daytime temperature of 34±1℃ may be partly due to difference in flesh characteristic and root condition but additional factors may be involved.
