Six RGB-derived VIs were used in this study. They were the blue green index (BGI); red-green ratio (RGR); normalized plant pigment ratio (NPPR); normalized green red difference index (NGRDI); normalized chlorophyll pigment index (NCPI); and plant pigment ratio (PPR) (Table4). The sel...
Indices related to photosynthetic pigment absorption, chlorophyll fluorescence emission, and canopy structure were determined (Gonzalez-Dugo et al., 2015). In the study, the normalized difference vegetation index (NDVI) resulted in poor yield prediction, potentially due to considerably large terminal ...
All three methods evaluated in this study reduce the artifactual production of chlorophyllide and are thus suitable for pigment extraction for HPLC analysis. The boiling method would be a practical choice when leaves are not too thick. However, it may convert a small fraction of chlorophyll a ...

8) showed that the RRMSE values of measured and simulated datasets of the unstratified RF-LNAnon model were 23.7% and 26.5%, respectively, while the accuracy of the RF-LNASum model, considering vertical heterogeneity, was markedly higher than that of the unstratified RF-LNAnon model. The ...
The mechanism responsible for carotenoid pigment synthesis in orange inner leaves of Chinese cabbage is still unclear, however, and limited molecular research has been conducted on the candidate gene. In this study, high-performance liquid chromatographic analysis indicated that orange leaf coloration in...
Furthermore, the obtained results were statistically compared with the reported spectrophotometric method [13] by using F-test and student t-test, and the statistical results were within the accepted levels as the t-value was 1.087 and F-value was 0.539 (tabulated values at 95% confidence limit...

X-axes identify the age of the leaf to which the values relate and the y-axes give the concentrations (as the area under curve) of the respective compound. See Figure 3 for an explanation of features. Table 2. Characteristics and tentative identifications of phenolic compounds expressed in ...
Based on the importance score derived from each machine learning method, the features with an importance score greater than the standard deviation of all score values were selected for further modeling. For the first modeling strategy, a total of nine regression models (three machine learning ...
