Weed Research 14, 415421.Bisen PS, Channy B (1983) Some observations on the surface of wheat leaves during the early stages of infection.Siddique AB, Hossain MH, Duveiller E, Sharma RC (2006) Progress in wheat resistance to spot blotch in Bangladesh.Journal of Phytopathology 154, 1622.Indeed, there is a very good correlation between Flav and LMA because both are controlled by the irradiance under which the leaf was grown so the Chl/Flav ratio would correspond to an LMA-corrected Chl,.e.Irrespective of all these problems, non-destructively measured leaf Chl content was used as a surrogate for leaf nitrogen (N) in plant productivity research (e.g.Vogelmann 1993 ) modeled recently for spad.
This new index called NBI (nitrogen balance index) is more of an indicator of C/N allocation changes due to N-deficiency than a measure of leaf nitrogen content per se (.
