Chlorophyll Fluorescence Detects Water Stress
Developing drought stress tolerance is one of the major targets of many crop breeding programs. Precise and efficient tools to measure drought stress is a vital requirement of these projects. One of the methods widely used by researchers is the measurement of chlorophyll fluorescence. Understanding the concept and the various plant processes that shape it… Continue reading…
Detect Stress by Measuring Photosynthesis
Plants face many environmental stresses, such as light, moisture, nutrients, temperature, and pollutants. Many of these factors are essential for plant growth, in optimum quantities; however, a dearth or excess can cause stress. As part of the plant’s overall response to stress, photosynthesis, which is one of the most important metabolic activities, also gets affected.… Continue reading…
A Tale of Two Lichens: Adaptations to Extreme Climate
In many extreme ecosystems, like deserts and polar regions, lichens play an important role as major carbon fixers and primary producers. Due to climate change, precipitation is expected to decrease and periods of dryness will lengthen. Lichens’ tolerance to periodic desiccation can make them vital for maintaining the carbon balance not only in their own… Continue reading…
Modifying Genetics, Physiology, and Biochemistry to Improve Drought Responses in Crops
Drought is the most common stress and has the largest effect on the growth and production of crops. Nearly a fourth of agricultural areas worldwide are affected by water shortage. Plants adapt to drought by altering their genetics, physiology, and biochemistry. Hence, these traits are being used to screen new cultivars, which can sustain growth… Continue reading…
Advances in Phytoremediation
Phytoremediation has many proponents to treat widespread chemical contaminants in soil, water, and air. It is low-cost, eco-friendly, and doesn’t require complicated technology and infrastructure. As it is a new branch of science, it is necessary to understand the processes involved in the different methods of phytoremediation to advise decision-making for application of this technology.… Continue reading…
How to Analyze Photosynthesis in Plants: Methods and Tools
Photosynthesis: Why is it important? Life as we know it would be impossible without photosynthesis. Outside of providing the essential elements that support life on earth, photosynthesis is of special importance to the food and agriculture industry, as well as for ecologists studying climate change. In addition, there are many commercial enterprises which depend heavily… Continue reading…
The Latest Advances in Photosynthesis Measurement
Photosynthesis Update 2019 Photosynthesis is undoubtedly one of the most important physiological processes on Earth. It is the process by which plants, algae, and bacteria produce food. Photosynthesis makes these organisms the primary producers of the earth, as all other organisms feed on them for their energy source. People depend on this important process for… Continue reading…
Versatile Uses of Leaf Spectral Information
Leaf spectral signatures are non-destructive and are collected with handheld instruments onsite or with remotely sensed imagery. They have applications that range from basic and applied research to the day-to-day management of farms. Leaf spectral information is used to inform decisions for better control over operations to optimize food, fiber, and timber production. Leaf spectral… Continue reading…
How Leaf Reflectance Measures Plant Stress
Photochemical Reflectance Index (PRI) can be measured remotely to estimate several types of stress and nutrient deficiency in plants. It has been shown that PRI is an indicator of photosynthetic efficiency, which changes when plants face stress. Portable but accurate spectrometers that can make easy and rapid measurements of leaf spectral interactions help in establishing… Continue reading…
Cadmium Toxicity in Plants
Cadmium is a heavy, non-biodegradable metal that is toxic to plants, people, and animals. With increasing pollution and emission of cadmium, its levels in agricultural soils are increasing. The risk to humans is high due to consumption of cadmium-contaminated food. Modern applications of gas analysis and laser measurements are speeding up research in addressing the… Continue reading…
