Tobacco Stalks

The Tobacco stalk varies with the varieties of the plant. All of the species cultivated in the United States have stalks of a large size—much larger than many varieties grown in the tropics. Those of some species of tobacco are little and easily broken, which to a certain extent is the case with most varieties of the plant when maturing very fast. The stalks of some plants are rough and uneven, while those of others are smooth. Nearly all, including most of those grown in Europe and America, have erect, round, hairy, viscid stalks, and large, fibrous roots; while that of Spanish as well as dwarf tobacco is harder and much smaller. The stalk is composed of a wood-like substance containing a glutinous pith, and is of about the same shade of color as the leaves. As the plant develops in size the stalk hardens, and when fully grown is not easily broken.

The size of the stalk corresponds with that of the leaves, and with such varieties of the plant as Connecticut seed leaf, Virginia, Kentucky, Ohio, St. Domingo, and some others; both will be found to be larger than Spanish, Latakia, and Syrian tobacco, which have a much smaller but harder stalk. It will readily be seen that the stalk must be strong and firm in order to support the large palm-like leaves which on some varieties grow to a length of nearly four feet with a corresponding breadth. The stalk does not "cure down" as fast as the leaves, which is thought now to be necessary in order to prevent sweating, as well as to hasten the curing. Most of the varieties of the plant have an erect, straight stalk, excepting Syrian tobacco, which near the top describes more of a semi-circle, but not to that extent of giving an idea of an entirely crooked plant. The stalk gradually tapers from the base to the summit, and when deprived of its leaves presents a smooth appearance not unlike that of a small tree or shrub deprived of its twigs and leaves.
