This study describes the identification of Panax species using mitochondrial consensus primers. Initially, a total of thirty primers were tested in ten Korean ginseng cultivars and two foreign Panax species, P. quinquefolius and P. notoginseng. In the polymerase chain reaction (PCR) amplification results, three primers (cox1, nad1/2-3 and nad2/1-2) generated co-dominant polymorphic banding patterns discriminating Korean ginseng cultivars from P. quinquefolius and P. notoginseng. However, these primers could not generated polymorphisms among the Korean ginseng cultivars, and simply represented species-specific polymorphisms for P. quinquefolius and P. notoginseng. Primers PQ91 and PN418 were designed from the consensus sequence of nad1/2-3 region. Two banding patterns (A or B) were detected in PQ91. Korean ginseng cultivars and P. notoginseng shared the same banding pattern (A type) and P. quinquefolius was identified another banding pattern (B type). In the case of PN418, two banding patterns (A or B) were detected in the Korean ginseng cultivars and two foreign Panax species. Korean ginseng cultivars and P. quinquefolius shared the same banding pattern (A type) and P. notoginseng was identified another banding pattern (B type). The combination banding patterns of three Panax species, Korean ginseng cultivars (Panax ginseng C. A. Mey.), P. quinquefolius and P. notoginseng, was identified as 'AA', 'BA' and 'AB', respectively. Consequently, PQ91 and PN418 primer sets can be used to distinguish among Panax species.

완숙 복분자딸기(Rubus coreanus Miq.) 과실부의 냉동저장 중 품질 특성의 변화를 조사하였다. 저장 초기에 비하여 과실을 저장 할수록 산도는 감소하였고, 가용성고형분은 증가하는 것으로 나타났다. 색상의 경우 저장 초기에는 L, a값이 35.63, 6.74 value로 전체적으로 밝은 붉은 빛을 가졌지만, 냉동 저장되어지면서 28.56, 4.13 value로 유의적으로 감소되어짐에 따라 점차 어두워지고 붉은 빛은 감소하였다. 비타민 C
