What is Stress? What Types of Stress Do Plants Experience?

Plants experience stress just like humans. This stress can be caused by environmental factors, diseases, pests or human activities. Stress can negatively affect the growth, development and production of plants.

The most common types of stress experienced by plants are:

• Environmental Stress: Factors such as drought, flood, extreme heat, extreme cold, salt stress, light stress, air pollution are considered environmental stress.
• Biotic Stress: Factors such as plant diseases, harmful insects, weeds are considered biotic stress.
• Anthropogenic Stress: Factors such as pollution, soil destruction, and excessive irrigation resulting from human activities are considered anthropogenic stress.

What are the Effects of Plant Stress?

Plant stress can cause many negative effects. These effects are:

• Regression in Growth and Development: Stressed plants grow and develop more slowly than normal. This condition manifests itself with symptoms such as yellowing, wilting and falling of the leaves.
• Decrease in Yield: Stressed plants give less yield than normal. This leads to a decrease in the size, quality and nutritional value of fruits and vegetables.
• Increased Susceptibility to Diseases and Pests: Stressed plants become more susceptible to diseases and pests. This causes plants to get sick more easily and become infested with harmful insects.
• Death: Excessive stress can cause plants to die.

The Importance of Liquid Fertilizers on Plant Stress Tolerance

Liquid fertilizers are an important tool in increasing the stress tolerance of plants. plays a role. Liquid fertilizers provide plants with the necessary nutrients quickly and easily. These nutritional elements increase the resistance of plants to stress and reduce the damages caused by stress.

The mechanisms of liquid fertilizers in increasing plant stress tolerance are as follows:

• Creating Nutrient Deficiency: Plants need more nutrients when under stress. Liquid fertilizers meet this need of plants and eliminate nutrient deficiency.
• Increasing Antioxidant Levels: Liquid fertilizers increase antioxidant levels in plants. Antioxidants prevent cellular damage caused by free radicals and increase plants’ resistance to stress.
• Supporting Osmotic Regulation: Liquid fertilizers support osmotic regulation in plants. Osmotic regulation helps maintain water balance in plants’ cells, which increases resistance to stress.
• Adapting Hormone Production: Liquid fertilizers help regulate the production of stress hormones in plants.

Liquid fertilizers utilize different mechanisms to increase plants’ tolerance to various stress factors. In this section, we will examine in more detail how liquid fertilizers increase plant stress tolerance.

How Do Nutrient Elements Increase Tolerance to Stress

Plants need various nutritional elements to develop healthily and be resistant to stress. Each of these nutrients allows plants to respond differently to stress.

• Macro Nutrient Elements: Nitrogen (N), Phosphorus (P), Potassium (K), Calcium (Ca), Magnesium (Mg) and Sulfur (S) are called macronutrient elements. These are essential nutrients required in large quantities for plant growth.
  • Nitrogen (N): Nitrogen, which is necessary for the protein and chlorophyll synthesis of plants, plays a critical role in the repair of plant tissues and new tissue formation under stress.
  • Phosphorus (P): Phosphorus, which is important for energy transfer and cell envelope structure, supports the energy production of plants against stress and protects the integrity of cell envelopes.
  • Potassium (K): Potassium, which regulates water retention and controls the opening and closing of stomata of plants, increases the tolerance of plants to stress by reducing water loss in situations such as drought stress.
  • Calcium (Ca): Calcium, which plays an important role in the cell wall structure, helps plants to be more mechanically resistant to stress.
  • Magnesium (Mg): Magnesium, found in the chlorophyll structure, increases the photosynthesis capacity of plants and reduces stress-related growth retardation.
  • Sulfur (S): Sulfur, which is necessary for protein synthesis and enzyme activities, strengthens the defense mechanisms of plants against stress.
• Micro Nutrient Elements: Iron (Fe), Manganese (Mn), Zinc (Zn), Boron (B), Molybdenum (Mo), Copper (Cu) and Chlorine (Cl) micronutrients are called elements. These are nutrients that are required in smaller amounts for plant growth but are still vital.
  • Iron (Fe): Iron, which plays a role in chlorophyll synthesis, helps plants maintain their photosynthetic capacity by reducing stress-related chlorophyll loss.
  • Manganese (Mn): Manganese, which is important for enzyme activities, strengthens the antioxidant defense systems of plants against stress.
  • Zinc (Zn): Zinc, found in enzyme activities and hormone structure, helps plants maintain their hormone balance against stress and continue their growth processes.
  • Boron (B): Boron, which is necessary for cell wall structure and pollen germination, supports important functions of plants such as fruit and seed setting against stress.
  • Molybdenum (Mo): Molybdenum, which is necessary for nitrogen fixation and enzyme activities, regulates nitrogen metabolism against stress, especially in legumes.
  • Copper (Cu): Copper, which plays a role in the defense mechanisms of plants, increases resistance to stress, diseases and pests.
  • Chlorine (Cl): Chlorine, which is important for stomatal movement and osmotic balance, increases plants’ tolerance to stress by regulating water retention in situations such as drought stress.

Liquid fertilizers contain the macro and micro nutrients needed by plants in a balanced manner. In this way, plants can easily access the necessary nutrients when exposed to stress and become more resistant to stress.

Role of Hormones and Osmolytes

Liquid fertilizers not only provide the nutrients that plants need, but may also contain components that support plants’ own defense mechanisms against stress. Some of these components are:

• Hormones: Plants try to protect themselves by producing various hormones when exposed to stress. Natural or synthetic hormones contained in liquid fertilizers can strengthen the effect of hormones produced by plants themselves. For example, some natural hormones obtained from algae have the effect of increasing the root development and stress tolerance of plants.
• Osmolytes: Plants under stress increase the amount of low-molecular organic compounds called osmolytes in their cells. These compounds regulate water retention, reducing stress-related water loss of plants and increasing the resistance of cells to stress. Some liquid fertilizers support the natural osmolyte production mechanism of plants, thanks to artificially added osmolytes.

Antioxidants and Stress Tolerance

Plants produce harmful molecules called free radicals in situations of stress. These molecules cause damage by causing oxidative stress in plant tissues. Liquid fertilizers may be enriched with antioxidants. Antioxidants protect plant tissues from oxidative stress by destroying free radicals and reduce stress-related damage. For example, natural ingredients such as humic substances and vitamins can be added to liquid fertilizers to increase their antioxidant capacity.

Effects of Liquid Fertilizers Against Different Types of Stress

The effects of liquid fertilizers in increasing plant stress tolerance may also vary depending on the type of stress. Below, we will examine how liquid fertilizers provide benefits against the most common stressors:

• Drought stress: Liquid fertilizers help plants lose less water under drought stress because they contain elements such as potassium and chlorine that regulate water retention of plants. Additionally, if liquid fertilizers can contain ingredients that promote root development, they can also increase plants’ ability to absorb water from deeper in the soil.
• Salt stress: Salt stress occurs when dissolved salts in the soil prevent plants from absorbing water. Liquid fertilizers can increase plant tolerance to salt stress if they can contain components that support the osmotic regulation of plants.
• Heat stress: High temperature stress negatively affects growth and development by disrupting the enzyme activity of plants. Liquid fertilizers may contain ingredients that can help plants maintain their metabolic activity under heat stress. For example, some algae extracts have an increasing effect on the resistance of plants to heat stress.
• Cold stress: Low temperature stress causes ice crystals to form in the cells of plants, leading to tissue damage. If liquid fertilizers can contain elements such as calcium that strengthen the cell wall structure of plants, they can increase the resistance of plants to cold stress.

As a result, liquid fertilizers have a versatile effect in increasing the resistance and tolerance of plants to stress. Thanks to components such as balanced nutritional content, hormones, osmolytes and antioxidants, liquid fertilizers contribute to a healthy and sustainable agriculture by reducing the stress-related yield loss of plants.
