Abstract

This study was conducted to investigate the effects of light intensity and temperature on the physiological characteristics and growth of ginseng leaves. The higher the transmittance of the shade, the greater the area was decreased. In contrast, however, the amount of transpiration was increased. There was no significant difference in the number of stomata, but the size of stomata was distinctively decreased. The higher the transmittance of the shade, the more the contents of total chlorophyll, chlorophyll a and b, and cartooned were decreased. In contrast, however, the aye ratio of chlorophyll was increased. Regardless of temperature, the contents of chlorophyll providing maximum photosynthesis at the end of June and August were 2.1mg and 1 8mg/g F.W. respectively.

1. 일복하의 투광율이 높을수록 엽면적은 감소되고 증산량은 증가되었으며 기공의 수는 차이가 없었으니 기공의 크기는 현저히 감소되었다. 2. 일복하의 투과율을 높일수록 전체엽록소 및 엽록소 a, b의 함량이 감소되었고 a/b율은 증가되었으며 carotenoid 함량도 감소되었는데 최대 광합성을 가져오는 엽록소함량은 온도에 관계없이 6월말 조사에서는 2.1mg이었고 8월말 조사에서는 1.8mg이었다.
