Fig. 8From: Improving the prediction performance of leaf water content by coupling multi-source data with machine learning in rice (Oryza sativa L.)The 1:1 validation of the ND(1287,1673) and multi-source data coupling model for monitoring LWC at different growth stages. a, b represents ND + CWSI model validation of the booting and flowering stages, and c, d represents ND + Fv/Fm model validation of the initial and middle grain filling stages. Each symbol is the average value of 4 measurements. * and ** indicate significant correlation at 5% and 1% probability level, respectivelyBack to article page
