From: A spatio temporal spectral framework for plant stress phenotyping
Development of selected plant trait indicators over time for the control group as well as those subjected to the three abiotic stress factors. The translucent regions indicate one standard deviation from the mean for cultivation boxes subject to identical treatment conditions. The temporal evolution of two popular vegetation indices—Normalised Difference Vegetation Index (NDVI) and Normalised Difference Red-Edge Index (NDRE), averaged over the biomass in the boxes is also shown. The control group as well as plants subject to weed stress are observed to follow the standard phenological development [63], whereas the resource constrained plants do not reach senescence during the experimental period
