Chemical Investigation of "Trashy" Leaf Phenomenon in Australian-Grown Flue-Cured Tobacco

Abstract

Carbohydrates and nitrogen distribution in flue-cured tobacco leaves described as "trashy" were determined. Sugars in "trashy" leaf were as low as 3 per cent. and in "good" leaf as high as 28 per cent. "Trashy" leaf, relatively to normal leaf, had large total N, protein N, and ammonia N contents and low amide N values, while its weight per unit area was about 30 to 50 per cent. Less than that of "good" leaf. Uncured "affected" ,leaf also had low sugar and high N values and low weight per unit area.
