Detecting the Impact of Drought on Plants with User-Friendly and Inexpensive Techniques

Drought is a major environmental stressor that affects plant growth and survival. It is a common phenomenon in many parts of the world, and its impact on agriculture and food security cannot be overemphasized. However, detecting the impact of drought on plants has been a challenge for scientists due to the lack of user-friendly and inexpensive techniques. In this article, we will explore some of the techniques that have been developed to detect the impact of drought on plants.

Introduction

Drought is a natural disaster that affects plant growth and survival. It occurs when there is a prolonged period of low precipitation or when there is an imbalance between precipitation and evapotranspiration. Drought can lead to reduced crop yields, loss of biodiversity, and even famine in extreme cases. Therefore, it is important to detect the impact of drought on plants so that appropriate measures can be taken to mitigate its effects.

Traditional Techniques for Detecting Drought Stress

Traditionally, scientists have used various techniques to detect drought stress in plants. These techniques include:

Leaf Water Potential

Leaf water potential is a measure of the water status of a plant. It is determined by measuring the pressure required to extract water from a leaf. A decrease in leaf water potential indicates that the plant is experiencing water stress.

Stomatal Conductance

Stomatal conductance is a measure of the rate at which water vapor diffuses through stomata in leaves. A decrease in stomatal conductance indicates that the plant is experiencing water stress.

Chlorophyll Fluorescence

Chlorophyll fluorescence is a measure of the efficiency with which photosystem II (PSII) converts light energy into chemical energy during photosynthesis. A decrease in chlorophyll fluorescence indicates that PSII has been damaged due to water stress.

New Techniques for Detecting Drought Stress

In recent years, new techniques have been developed to detect drought stress in plants. These techniques are user-friendly and inexpensive, making them accessible to a wider range of scientists and farmers. Some of these techniques include:

Infrared Thermography

Infrared thermography is a non-destructive technique that measures the temperature of leaves using an infrared camera. A decrease in leaf temperature indicates that the plant is experiencing water stress.

Chlorophyll Content

Chlorophyll content is a measure of the amount of chlorophyll present in leaves. A decrease in chlorophyll content indicates that the plant is experiencing water stress.

Proline Content

Proline is an amino acid that accumulates in plants under water stress. Proline content can be measured using spectrophotometry or high-performance liquid chromatography (HPLC).

Conclusion

Detecting the impact of drought on plants is crucial for ensuring food security and mitigating the effects of climate change. Traditional techniques such as leaf water potential, stomatal conductance, and chlorophyll fluorescence have been used for many years to detect drought stress in plants. However, new techniques such as infrared thermography, chlorophyll content, and proline content have been developed to make detection more user-friendly and inexpensive.
