Comparison of Cured Versus Uncured Leaf Samples for Evaluation of Inorganic Composition of Tobacco
Year: 1968
Type: article
Abstract: Cured and uncured tobacco leaf samples from plots receiving six rates of dolomitic limestone at six locations over a 3-year period were analyzed for K, Mg and Ca. Average cation percentages of cured samples were greater than those of uncured samples by a factor of 1.23, and the two sets of data were highly correlated. Neither dolomitic limestone treatments nor different "primings" had any appreciable effect on the ratio of cured/uncured cation content. Ratios associated with different locations were, in general, also very similar.When cation percentages in cured leaf samples were predicted from uncured leaf analyses, the effects of treatments and primings were almost identical to the actual response pattern. The precision of the variance analyses of data from cured samples was also comparable to that from the uncured samples.It was concluded that analysis of uncured leaves can be used to predict accurately the inorganic composition of the cured product. Such a procedure would be particularly useful in determining soil conditions and treatments which will produce tobacco with desirable chemical properties.
