Abstract

This study was conducted to investigate the effect of brushing on overgrowth inhibition, growth, yield and starch content in spring-grown potato in the netted house. The plant growth of aerial parts was inhibited with growth stage and brushing duration. Especially, The number of lateral branches decreased greatly with brushing duration. The stem length and stem diameter were not different significantly between brushing and non-brushing on May 6. But the stem length was long in later growth stage but short in longer brushing duration. Chlorophyll content by SPAD increased with growth stage regardless of non-brushing duration and ranged from 30 to 36 mg/$\textrm{cm}^2$. The fresh and dry weight of aerial part and tuber were heavy in longer brushing duration. Starch content was higher in brushing treatment as compared to non-brushing and increased with brushing duration.

본 연구는 망실 하우스 내에서 봄감자 재배 시. brushing 처리가 감자의 도장 방지와 생육과 수량 및 체내 전분함량에 미치는 효과를 구명하기 위하여 수행하였다. 지상부의 생육은 생육 후반기로 갈수록, brushing 처리시간이 길수록 감소하였다. 측지 수도 처리시간이 길수록 감소하는 경향이었다. 경장과 경경은 5월 6일에는 처리간에 비슷하였으나 생육 후반기로 갈수록 모든 처리에서 증가하였는데 평균적으로 30∼36mg/100 $\textrm{cm}^2$였다. 지상부ㆍ지하부의 생체중과 건물중은 처리시간이 긴 것이 무거웠고, 전분 함량은 무처리에 비해 brushing 처리한 것이, 그리고 처리시간이 긴 것이 높았다.
