تأثیر متیلجاسمونات بر خصوصیات کمی و کیفی توتون کوکر 347 در آبیاری با سطوح مختلف کلر

In order to study of effect of metyl Jasmonate on quantitative and qualitative characteristics of Cocker 347cultivar in different chloride concentrations of water irrigation, an experiment was carried out in Rasht Tobacco Institute with 3 levels chlorine water irrigation (50, 150 and 300 mg/Lit) and 2 levels of Metyl Jasmonate application (0 and 30 micromolars) with 4 replications in factorial combinations basis on a completely randomized design in pots. The results showed that there were no significance differences between treatments in all characteristics (Leaf number per plant, Height of plant, Length and Width of leaf, Leaf Area, Fresh weight, Yield, Income, Sugar and Nicotine percent), only Nicotine concentration in upper leaves were significant (p≤0.050). In this case, treatment 4 (Cl300, J0) with 2.28% was highest and treatment 3 (Cl300, J0) was lowest with 1.21% in nicotine content.
