버얼리種 乾燥時 철재파이프비닐하우스의 遮光程度가 煙草葉의 理化學性에 미치는 影響 = Effects of Shading Rate of Pipe Plastic House for Curing on the Physical and Chemical Characteristics in Burley Tobacco Leaves

다국어 초록 (Multilingual Abstract)

This study was conducted to investigate the effects of shading rate of the pipe house covered with transparent plastic during curing on the variation of physical and chemical characteristics in burley tobacco. The results are summarized as follows.
The decomposition of chlorophyll and total sugar during curing were insufficient in lower shading rate, particularly in no shading. In the case of higher shading rate, the content of ammonia nitrogen was more increased and that of amino-nitrogen was less increased. Chlorogenic acid was less decreased with lower shading rate.
Yellowished and photobleached leaves under higher than 60% shading were markedly decreased, while house-burned leaves was slightly increased. Though yellowished leaves greatly decreased by higher shading rate, but there was insufficient to prevent yellowished leaves. Especially, the treatment of no shading overdried the tobacco leaves during the initial stage of curing as indicated by the 50% abnormal leaves from half of total leaves being marked as yellowish.
