Abstract
Metabolic rules of nitrogenous compounds(total N,nicotine,protein,and amino acid)in central and upper leaves of K326 have been studied with different amounts and forms of N fertilizer.The content of total N,protein,amino acid in central leaves increases as the amount of nitrogen as the amount of nitrogenous fertilizer increase,but nicotine shows no obvious change.The form of N doesn't have any obvious influence on the content of total N,protein or amino acid in central leaves.The nicotine content in tobacco leaves in the mature stage declines with increasing ratio of NO -1 3-N fertilizer.The content of all nitrogenous compounds in upper leaves is obviously affected by the amount of N.It becomes higher when more N is used.The content ofnitrogenous compounds in a treatment of 180?kg/hm 2 is much greater than that in the treatments of 60?kg/hm 2 and 120?kg/hm 2.The effect of the form of N on nitrogenous compounds in upper leaves is consistent with that in central leaves.
