Abstract

The effects of selenium (Se) and germanium (Ge) fertilization on the growth and quality of Chinese cabbages cultivated in spring and autumn and peppers cultivated in spring were investigated. $Se\;(Na_2SeO_4)\;and\;Ge\;(GeO_2)$ were supplied 5, 10, or 20 times in an aqueous solution of 0, 2, 4, or $8mg{\cdot}L^{-1}$ during the cultivation of Chinese cabbages and peppers. The fresh weight of Chinese cabbages increased by Ge fertilization with high concentration. But it was not affected by Se fertilization. The content of vitamin C increased by 10 times application with $4mg{\cdot}L^{-1}$ of Se or Ge. The concentration of Se in Chinese cabbage increased according to increasing concentration of Se fertilization. Se concentration was higher in the outer leaves than in the inner leaves. Se concentration in the mesophyll was higher than that in the midrib. Ge fertilization increased the uptake and concentration of Ge in autumn-cultivated Chinese cabbages. Se and Ge fertilization did not affect the fresh weight of peppers. The content of vitamin C in pepper increased by 20 times application of $2mg{\cdot}L^{-1}$ of Se. Vitamin C content in red peppers was twice as much as in green peppers.

셀레늄과 게르마늄 처리 시 배추(봄, 가을배추)와 고추의 생육과 품질의 변화를 조사하였다. 셀레늄처리에 의한 봄배추와 가을배추의 생체중은 차이가 없었고 Ge 처리시 높은 농도에서 생체중이 감소하였으나 고추에서는 차이가 없었다. 배추의 셀레늄 처리 경우 비타민 C 함량은 Se $4mg{\cdot}L^{-1}$ 10회 처리가 무 처리에 비하여 증가하였으며 게르마늄 처리 경우 Ge $4mg{\cdot}L^{-1}$ 10회 처리와 Ge $8mg{\cdot}L^{-1}$ 5회 처리에서 증가하였다. 고추에서 셀레늄 처리에 의해 Se $2mg{\cdot}L^{-1}$ 20회 처리가 높았으며 홍고추가 풋고추에 비교하여 비타민 C 함량이 약 2배가량 많았다. 봄, 가을배추 부위별 셀레늄함량은 외엽>중엽>내엽 순으로 많았고 엽육부위가 중륵에 비해 높았으며 농도의 증가에 따라 증가하는 경향이었다. 게르마늄 처리 시 가을 배추 잎에서 모든 처리구가 무 처리에 비해 높았다.
