Abstract

This study was conducted to investigate correlation between external factors of chicory root and chicon fresh weight, whereby, to provide basic information of external yardstick of producing standardized chicon. For correlation between external factors (root diameter, root weight) of chicory root and chicon fresh weight were highly correlated. The relationship between external factors (root diameter, root weight) of chicory root and chicon fresh weight, root diameter was strongly affecting chicon fresh weight due to significant at its regression coefficient ($6.06^{***}$). In order to verity this correlation, the root diameter (x) of chicory that were 3 different varieties were based on the 4 different root diameter treatments, such as x ${\leq}$ 30 mm, 30 < x ${\leq}$ 40 mm, 40 < x ${\leq}$ 50 mm and x > 50 mm. The chicon production increased as root diameter increased and the chicon fresh weight, chicon width, and the number of leaves increased as well. Therefore, the measure of root diameter of chicory instead of the internal factors (carbohydrate, and so on.) can be used to predict the chicon fresh weight.

본 연구는 치커리 뿌리의 외적요인과 치콘의 생체중간에 관계를 분석하고, 이중 높은 상관관계를 보인 요인을 치콘 규격 생산에 적합한 종근의 외적 판단기준으로 이용할 수 있는 자료를 만들고자 수행하였다. 종근의 외적요인인 근경(0.726)과 근중(0.508)의 상관관계를 보면 모두 생체중과 정(+) 상관관계를 보였다. 치콘 생체중에 영향을 주는 종근의 외적요인인 근경과 근중 중 상대적으로 높은 영향인자를 찾기 위하여 다중회귀 분석을 실시한 결과 치커리 근경의 회귀계수($6.06^{***}$)만이 유의하여 치콘 생체중에 영향을 미치는 것으로 나타났다. 3가지 품종의 치커리를 근경(x) 크기별로 x ${\leq}$ 30mm, 30 < x ${\leq}$ 40mm, 40 < x ${\leq}$ 50mm, x > 50mm로 분류하여 치콘을 생산한 결과 거의 모든 품종에서 근경이 증가할수록 치콘 생체중, 치콘 폭, 엽수 등이 증가하였다. 이상의 결과로 보아 치커리 종근의 탄수화물 함량 등 내부요인을 분석하지 않고, 상대적으로 간편한 외적요인인 치커리 근경을 수확 후 측정하여 치콘의 생체중을 미리 판단할 수 있을 것으로 사료되었다.
