Abstract:

This paper briefly discussed the principles and characteristics of spectral reflectance. Commonly used reflectance index in turfgrass stress research was introduced. The application of spectral reflectance in turfgrass stress research, such as pest, drought, traffic, nutrient, salinity stress was analysed separately. It suggested that spectral reflectance is a fast, easy, and accurate tool for identification of biotic and abiotic stress, assessment of plant physiological status, prediction of nutrient availability for turfgrass, indicating its broad application prospects in turfgrass research. This review also summarised the data transformation and smooth manipulation method, the importance of the data handling for correlation analysis and prediction model was emphasised. The purpose of this review is to provide a new method and angle for domestic turfgrass physiologist and turfgrass managers.
