Effect of ammonium and nitrate nitrogen on the volatile oil of flue-cured tobacco under vinyl mulching cultivation.
1988
Chang K.W.
This study was focussed to compare the concentrations of the volatile oil components of flue-cured tobacco grown by two types of nitrogen-ammonium and nitrate-under vinyl mulching. The content of nicotine was lower and reducing sugars degraded from starch had higher content in NO3-N application than NH4-N. The concentrations of furfural, benzyl alcohol, and phenethyl alcohol in the cured leaf were not different between NH4-N and NO3-N treatments. Some of the important flavour components - linalool, solanone, damascenone, neophytadiene, and oxyolanone + megastigmatriene-one had much higher concentrations in NO3-N than NH4-N application. In conclusion, nitrate nitrogen was more favorable to decrease nicotine and to increase some important flavour components of cured leaf than ammonium nitrogen.
