How Does the Red-to-Far-Red Fluorescence Ratio Reveal Plant Stress?
The red-to-far-red fluorescence ratio is sensitive to changes in environmental and growing conditions; therefore, it can be used as an early indicator of plant stress. Photosynthesis, especially the sensitivity of photosystem II (PS II) to stress, is leveraged while using the ratio. The red-to-far-red ratio has several practical applications in precision agriculture and in developing… Continue reading…

What is Senescence in Trees and Why Is It Important?
Senescence occurs at the cell, tissue, organs, and individual levels. Organ senescence is consequential in trees as it helps “recycle materials” within an individual tree to maintain function and productivity. Organ and whole tree senescence are also crucial for nutrient cycling, wildlife diversity, and forest productivity. Senescence is an integral part of all living organisms,… Continue reading…
Can Spectroscopy Predict Leaf Traits Across Ecosystems?
Yes, but with caveats. Leaf traits are used to understand plant growth, functional diversity, and ecosystem processes. Several traits spanning functional groups and geographies can be easily predicted using general models based on spectral data. However, all models cannot have global applications without validation, as the relationship between traits and spectral data is not the… Continue reading…

Plant Responses to Heat Stress
Heat stress affects crop development, growth, and productivity. Plants have adaptive responses for either avoidance or tolerance of heat stress. The plant responds to heat, which can be molecular, biochemical, cellular, physiological, and morphological, and is being used by scientists to develop new cultivars for the future. The increase in temperature due to climate change… Continue reading…
How to Measure 7 Types of Stress in Plants Using Leaf Spectroscopy
Leaf Spectroscopy can measure seven common stresses that crops encounter. The crop leaf stressors are drought, nutrient deficiency, temperature, pests, diseases, salinity, and herbicides. Spectral changes due to physiological, anatomical, and chemical alterations triggered by stress are used in its measurement. Various methods are visual, multispectral, hyperspectral, thermal imaging, and light interaction. Yield depends on… Continue reading…
How Climate Change Impacts Leaf Pigments
Chlorophylls, carotenoids, and anthocyanins are the pigments coloring leaves green, orange, and red, respectively. Chlorophyll degradation, a crucial phenomenon in autumn, is getting delayed due to climate change cutting the fall color change time short with repercussions on nitrogen cycling and carbon storage. Warm temperature makes tropical forest leaves darker and reduces light reflection, which… Continue reading…
