Modeling Leaf Image, Chlorophyll Fluorescence, Reflectance From SPAD Readings

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2014
Many remote sensing technologies were used to evaluate plant physioecology. However, few studies currently existed on the comparisons and the relationships among various remote sensing analyses methods. The objective of our study was to investigate the relationship of leaf image, chlorophyll fluorescence, reflectance with SPAD, and build the models ...

Chlorophyll fluorescence imaging accurately quantifies freezing damage and cold acclimation responses in Arabidopsis leaves

Plant Methods, 2008
Background Freezing tolerance is an important factor in the geographical distribution of plants and strongly influences crop yield. Many plants increase their freezing tolerance during exposure to low, nonfreezing temperatures in a process termed cold ...

Chlorophyll fluorescence algorithm development for the FLuORescence Imaging Spectrometer (FLORIS)

, 2023
Modelar la reflectividad de los cuerpos de agua es un desafío debido a la variabilidad espectral causada por efectos de absorción y dispersión de los distintos componentes presentes en el agua. De igual manera, la detección de la Fluorescencia de la Clorofila Inducida por el Sol (SICF) es una tarea compleja, aún más complicada por la presencia de un ...
