摘要： Leaf thickness is one important index of describing plant growing conditions. But the measurements now are all tedious and destructive. In order to carry out real-time, live, non-destructive testing of leaf thickness, the study took cotton leaves as the research object. The correlations of leaf thickness with reflectance, vegetable index and spectral figure index were analyzed separately. And then the cause of correlation was studied. Three regression models were set up with the 3 parameters which had high correlation with leaf thickness. Among these models, the highest relative error is 7.4%, and the RMSE is 0.051 mm. It is feasible to measure alive leaf thickness untouchably with Hyper spectrum.
