摘要
Non destructive method for estimating the water stress of plant leaves without requiring long time Make sure. The reflected light from the light irradiated plant leaves is measured by a near-infrared spectrometer to obtain a reflection spectrum, and the spectral data over the wavelength range of near infrared has been converted into absorbance spectral data and second-order derivative In the multiple regression analysis and collinearity, we divided several models, selected representative wavelengths, and tested the accuracy of the prediction using some spectral data, and estimated the correlation coefficient (R), the predicted standard error (SEP), and the leaf moisture tensioner The prediction value of LWP is calculated.
