본 연구는 생식생장기의 고온스트레스에 의한 콩의 생육과 수량에 미치는 영향을 구명하고자 대립종인 황금콩과 소립종인 풍산나물콩을 이용하여 수행하였다. 고온처리에 따라 두 품종 모두 초장은 증가하였으나 엽면적 및 건물중은 크게 감소하였다. 고온처리에 따라 개체당 협수는 감소하지 않았으나 잎수와 100립중이 감소하여 전체 수량이 황금콩과 풍산나물콩 모두 약 45% 감소하였다. 또한 잎, 줄기, 뿌리의 질소함량에서도 고온처리에 의한 감소를 보여 주고 있다

This study was conducted to investigate the effect of high-temperature during the reproductive growth period on the soybean growth and yield. Two soybean cultivars, Hwangkeumkong (HKK) and Pungsannamulkong (PSNK) were used in this study. By high-temperature treatment, plant height was increased in the two soybean cultivars, however, leaf area and dry weight were greatly reduced. Number of pod per plant was not changed by high-temperature treatment. However, number of seeds and 100 seed weight were reduced in two soybean cultivars. As compared with control, yield were decreased by 45% in both HKK and PSNK. It was also appeared that nitrogen contents in leaf, stem, and root of the HKK and PSNK were decreased by high-temperature treatment.
