Investigation of Leaf Diseases and Estimation of Chlorophyll Concentration in Seven Barley Varieties Using Fluorescence and Hyperspectral Indices
Leaf diseases, such as powdery mildew and leaf rust, frequently infect barley plants and severely affect the economic value of malting barley.Early detection of barley diseases would facilitate the timely application of fungicides.In a field experiment, we investigated the performance of fluorescence and reflectance indices on (1) detecting barley
