CHEMICAL CONSTITUENTS AND PHYSICAL PROPERTIES OF DIFFERENT PRIMING OF SEVEN GENOTYPES OF ORIENTAL TOBACCO
(2021) Hevi Rahim Karim
This investigation was carried out at Zrguez Tobacco Station in Sulaimani governorate during the summer season of 2010, to estimate the chemical constituents and some physical properties of seven oriental tobacco genotypes (Nicotiana tabacum L.). The seven oriental tobacco genotypes, namely; Gullsur, Gullspi, Madara, Pazarjik, Bulgari, Line 10 and Line 18 which were grown in Zrguez Tobacco Station. The product sun cured and stored in the warehouse for a long time to induce natural fermentation and aging. The leaves from three primings were used to determine chemical constituents, which were (the percentage of reducing sugar, nicotine content, total nitrogen, C/N ratio, total ash, volatile oil, potassium content and chloride content), and estimating of some physical properties which were (leaf area, leaf thickness, weight/unit area and strip yield). The factorial experiment was laid out according to Completely Randomized Design (CRD), with three replicates. Tobacco leaves from lower, middle and upper primings were prepared to study the differences between genotypes, primings, and their combinations in some chemical constituents and physical properties.
