收穫時期 및 黃變期間에 따른 黃色種 담배 乾燥中 內容成分 含量 變化 = Effects of Harvesting Time and Duration of Yellowing Stage on the Chemical Composition of Tobacco Leaves during Flue-curing Process

다국어 초록 (Multilingual Abstract)

This study was conducted to investigate the effects of harvesting time and periods of yellowing stage on the chemical composition of the pit-covered mulching cultured flue-cured tobacco leaves during flue-curing process.
The results are summarized as follows :
1.The changes of chlorophyll content in tobacco leaves was influenced more by harvesting time than period of yellowing stages. As the early harvesting, the chlorophyll content of cured leaves was appeared high in prolonged yellowing time case.
2.The content of sugar in tobacco leaves were increased in early stage during flute-curing process with delayed harvest and prolonged yellowing period.
3.Total nitrogen and amono-nitrogen in fresh and cured leaves decreased at the harvesting time delayed. Amino-nitrogen content of cured leaves at early harvesting increased as the yellowing time was prolonged, but increased as the yellowing time was shortened in the case of late harvesting.
