Measuring Heat Stress on Forest Trees

January 30, 2024 at 6:27 pm | Updated January 30, 2024 at 6:27 pm | 12 min read

The impact of high temperatures directly and alone on trees is significant without the associated drought. Heat effects are recorded at cellular, leaf, and tree levels, inhibiting tree growth and productivity or even mortality. More research is necessary to fully understand the effects of heat stress, which must be supported by on-site, non-destructive data collection… 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 Does Crop Canopy Structure Affect Yield? 5 Key Factors Explained

Crop canopy attributes influencing yield are leaf area, inclination angle, ground cover fraction, and chlorophyll content. The attribute that could increase yield by optimizing photosynthetic efficiency, light interception, water use efficiency, or reducing weeds, stress, and disease can vary on the relevant crop physiology. Increasing emphasis on crop canopy attributes can maintain and increase yield… Continue reading…

What is Plant Productivity, and How to Measure It

Plant productivity provides society with ecosystem services and is the basis of all heterotrophic levels. Environmental factors like light, temperature, and precipitation, determined by latitudes, influence plant productivity patterns, which are most in the tropics and decrease towards the poles. The combined negative and positive interactions are essential biotic factors influencing plant productivity. Plant productivity… Continue reading…

Exploring Plant Nutrient Status: Q&A on Chlorophyll Fluorescence Measurements

This Q&A article explores the fascinating world of chlorophyll fluorescence, a process where plants emit light from energy loss during photosynthesis, and how it relates to plant nutrient status. Chlorophyll fluorescence measurements provide valuable insights into plants’ photosynthetic efficiency and overall health, allowing researchers and agriculturalists to optimize nutrient management techniques. By utilizing advanced root… Continue reading…

A Conversation with Forest Ecophysiologist Sybil Gotsch: Exploring Climate Change and Forest Productivity.

In this conversation between Galen George and Sybil Gotsch, a forest ecophysiologist based at the University of Kentucky, we gain insight into Gotsch’s research on how plants respond to stress and how different communities of plants are impacted by climate change. Gotsch shares her experiences leading fieldwork in Costa Rica and Georgia and her plans… Continue reading…
