다국어 초록 (Multilingual Abstract)

This experiment was performed to investigate and to analyse the effects of sail moisture condition on growth, yields and content of nicotine and to study the adaptability to environment of oriental tobacco. 15 varieties (Samson Xanthi etc.) of oriental tobacco were applied in this experiment. Three levels of soil moisture condition were 30% (Damp) 45% (Moist), and 60% (Wet) to the maximum water holding capacity.
The results obtained are summarized as follows.
1.The number of harvested leaves was high in order Samsun〈 Basma〈 Xanthi Gaya〈 Bursa〈 Izmir and low in order Zichna 〉Samsun Holmus 〉Xanthi 〉Smyrna. But there were little differences among the treatments.
2.Percentage of dried up leaves showed no differences among the treatments. Among the varieties, it showed inverse proportion to the tendency of number of total leaves.
3.Leaf area had a tendency of Damp〈 Moist〈 Wet and showed significant difference between the plot of Damp and the plots of Moist and Wet. Among the varieties, Zichna and Mahola had remarkably broad leaves, Bursa, Nigrita, Smyrna, Xanthi and Drama etc. had narrow leaves, and the other varieties Showed no differences.
4.Dry weight of unit leaf area was low at the plot of Damp, and high at the plots of Moist and Wet. Among the varieties, that was appeared in order Baschibaglis〈 Xanthi〈 Nigrita〈 Smyrna. Xanthi Gaya, Zichna, Mahola and Samsun Holmus had light weight of unit leaf area.
5.There were significant differences on yieldg among treatments in order Damp〈 Moist〈 Wet. Especially, high significant differences of yields were appeared between the plot of Damp and the plots of Moist and Wet. Among the varieties, yields was high in order Izmir〈 Basma〈 Smyrna〈 Baschibaglis〈 Mahola and low in order Nigrita 〉Bafra 〉Samsun Holmes 〉Xanthi. Every variety has his own type of constitution of yields.
6.The content of nicotine was low in order Bursa 〉Mahola 〉Izmir 〉Basma 〉Samsun 〉Drama and those of these varieties were under 1.8%. And that was high in order Xanthi〈 Zichna〈 Samsun Holmus〈 Bafra〈 Nigrita〈 Xanthi Gaya〈 Smyrna, and those of these varieties were about 2.0∼3.8%. Among treatments, the plot of Damp had a tendency of low content of nicotine.
