  1. PTN, PN, PTS, PRS, PTK, PCL, PPE, PS, is the content of nitrogen, nicotine, total sugar, reducing sugar, potassium, chlorine, petroleum ether and starch content of leaves. We also showed the ratio of sugar/alkaloid (PSA) and the ratio of total N to total alkaloids (PNA) in this table. Values are means ± standard error. Means followed by the same letter for a given factor are not significantly different at P < 0.05 (Duncan’s test).
