Comparative Study on the Effect of the Climatic Conditions on Biological, Economic and Chemical Characteristics of Large-Leaved Tobacco Samples of Burley and Virginia Groups
Journal Title: Ecologia Balkanica - Year 2014, Vol 5, Issue 0
Abstract
Correlations between the climatic characteristics: average daily temperature and precipitation sum, on the one hand, and, the biological, economic and chemical characteristics of ten large-leaved Burley and Virginia tobacco samples, on the other, were studied and compared. Except for the vegetation period length, for which a positive correlation was reported, the effect of the climatic conditions on the biological characteristics was insignificant. In both tobacco types the amount of precipitation showed positive correlation with the yield and negative one with the nicotine content (p<0.05). Out of all the studied large-leaved tobacco samples, the climatic conditions had a stronger effect on the biological, economic and chemical characteristics of Burley tobacco, i.e. that tobacco type was influenced to a larger degree by the environmental conditions.
