광량과 파프리카 품종에 따른 수량과의 상호관계

The study was aimed at the development of the simple linear regression model to estimate the fruit yield of sweet pepper and to support decision-making management for growing sweet pepper crop in Korea. For quantitative analysis of relationship between environmental data and periodical yield of sweet pepper the data obtained from the commercial Venlo-type glasshouse for 2 years. Obtained periodical yield data of five different cultivars and radiation data were accumulated and fitted by linear regression. A significant linear relationship was found between radiation integral and fruit yield, whereas the production per unit of radiation was different between cultivars. The slope of linear regression could indicate as light use efficiency for fruit production (LUE F , g · MJ ?1 ). LUE F of ‘Ferrari’ was 5.85 g · MJ ?1 , ‘Fiesta’ 5.32 for first year and 4.75 g · MJ ?1 and for second year, ‘President’ was 4.66 g · MJ ?1 , ‘Cupra’ was 3.86 g · MJ ?1 , and ‘Boogie’ was 6.48 g · MJ ?1 . The amount of light requirement for the unit gram of fruit was between 25.88 J · g 1 , for ‘Cupra’ and 15.42 J · g ?1 for ‘Boogie’. Although we found the linear relationship between radiation and fruit yield, LUEF was varied between cultivars and as well as year. The linear relationship could describe the fruit yield as function of radiation, but it needed more variable to generalization of the production, such as cultivar specifications, temperature, and number of fruits set per plant or unit of ground.
