Abstract
This study was carried out to investigate the effect of the red light on embryo tissue of barley during germination. The solubility of starch in endosperm of germinated barley was different between dark and red treatments at the 3rd day of germination, but was increased by the red light from the 4th day of germination. Blue value of the starch in the germinated barley decreased rapidly from 0.42 at the 1st day to 0.13 at the 6th day in the dark, and same tendency was found in the red light, but blue value was lower in the red light than in the dark. Aleurone cell wall was swollen much faster in the red light than in the dark during germination. The cell wall was broken down more greatly in the red light than in the dark at the 5th day of germination.
보리의 발아중 호분층 및 배유조직에 미치는 적 색광의 영향을 조사하였다. 발아일수가 경과함에 따라 적색광 조사에 의한 배유조직의 친분입자의 용해현상이 발아 3일까지는 암소와 큰 차이가 없었으나 4일부터는 현저히 촉진되었다. 맥아내 전분의 blue value는 암소에서 발아 1일에 0.42, 6일에 0.13으로 발아일수가 경과함에 따라 현저히 감소하였으며, 적색광 처리에서도 동일한 경향을 보였으나 암소보다 그 값이 낮았다. 호분층 세포벽의 팽윤 및 붕괴현상은 발아일수가 경과함에 따라 촉진되었는데 암소에 비하여 적색광 조사에서 현저하였으며 특히 적색광 조사시의 발아일에서 세포벽의 붕괴현상이 심하였다.
