  • Use of nondestructive spectroscopy to assess chlorophyll and nitrogen in fresh leaves

    Creator:
    Ding, Pinghai
    Abstract:
    Four aspects of factors influencing the accuracy of nondestructive chlorophyll (Chl) and nitrogen (N) measurement in fresh leaves were studied: (1) optimum wavelength (OW) identification; (2) indices development and evaluation; (3) influence of leaf properties; and (4) influence of meter parameters and sampling technique. Results were used to develop indices...
