Abstract

This study was carried out to investigate the effect of light quality on root yield and ginsenoside contents of 4-year-old ginseng by using the fourfold polyethylene shading net with different colors, blue and red color, compared to blue-black (3:1) mixed shading net as control. Control and blue shading net occurred higher root yield, especially, in tap root growth than red one, whereas transmitted quantum in red shading net was higher than those in blue one or control. However, red shading net caused the highest content of total ginsenoside, especially, Rg1 content, as compared to blue and control. We assumed that the increased content of ginsenoside is not caused by light quality such as red, but is due to the increase of relative ratio of ginsenoside in whole root tissue arising from the reduced root growth.

인삼 4년생을 대상으로 해가림 색상을 달리하여 재배 시험한 결과, 대조구인 4중직 PE 차광망(청색 3 + 흑색 1중직)이나 청색 4중직 차광망에서 재배된 인삼의 뿌리 근중은 적색 4중직 차광망보다 높게 나타났으며, 대조구보다 청색과 적색에서 동체의 비율이 낮고 지근의 비율이 높아 투광량이 많아지면 동체의 생장이 감소하고 지근의 생장은 증가하였다. 뿌리에 함유된 진세노사이드 함량은 적색 해가림재배에서 가장 높게 나타나 투광량이 증가할수록 진세노사이드 함량이 증가되었으며, 특히 진세노사이드 Rg1의 함량이 유의적으로 더 높았다. 색상에 따른 진세노사이드 함량차이는 해가림 색상 차이에 의해 생합성 과정이 영향을 받은 것이 아닌 생육량의 차이에 따른 결과로 판단되었다.
