What are seed primers?

Seed primers are a type of treatment used to enhance the germination and early growth of seeds. They are designed to activate dormant genes and improve the ability of seeds to absorb water, increase enzyme activity, and deliver essential nutrients. Seed primers can be in the form of biostimulants, priming solutions, or seed coatings, and they help to improve seedling vigor, increase resistance to stress, and enhance nutrient uptake.

Benefits of using seed primers

Enhanced germination rate

One of the major benefits of using seed primers is an enhanced germination rate. Seed priming treatments help to break seed dormancy and stimulate seed germination. By activating dormant genes and improving water absorption, seed primers promote faster and more uniform germination, leading to a higher overall germination rate.

Faster early growth

Seed primers also contribute to faster early growth of seedlings. By improving enzyme activity and nutrient delivery, seed primers enable seeds to utilize their energy reserves more efficiently during the early stages of growth. This results in quicker emergence and establishment of seedlings, giving them a head start in terms of growth and development.

Improved seedling vigor

Seedling vigor refers to the overall health and strength of young seedlings. Seed priming treatments have been shown to enhance seedling vigor by improving the physiological processes within the seeds. Activating dormant genes, enhancing enzyme activity, and providing essential nutrients all contribute to healthier and more robust seedlings, which are better equipped to withstand environmental stresses and compete with weeds.

Increased resistance to stress

Stress can have a detrimental effect on seed germination and early growth. Seed primers help to increase the resistance of seeds and seedlings to various forms of stress, such as drought, salinity, and disease. By inducing stress tolerance mechanisms, seed priming treatments provide a protective shield for seeds and seedlings, allowing them to overcome adverse conditions and continue to grow and develop.

Enhanced nutrient uptake

Nutrient uptake is essential for the growth and development of plants. Seed primers improve nutrient uptake by activating dormant genes and enhancing the physiological processes within the seeds. This results in improved efficiency of nutrient absorption and utilization by the seedlings, leading to healthier growth and higher crop yields.

Types of seed primers

Biostimulants

Biostimulants are a type of seed primer that contain naturally occurring substances, such as plant growth hormones, microorganisms, and organic matter. These substances stimulate plant growth and enhance plant tolerance to abiotic stress. Biostimulants can be applied directly to seeds or used as a seed treatment solution.

Priming solutions

Priming solutions are liquid formulations used to treat seeds before sowing. These solutions typically contain compounds that help to activate dormant genes, improve water absorption, and enhance enzyme activity. Priming solutions are commonly used for large-scale seed treatments, as they can be easily applied using seed treatment equipment.

Seed coatings

Seed coatings involve applying a thin layer of material onto the surface of seeds. These coatings can contain biostimulants, polymers, or other substances that provide specific benefits to the seeds. Seed coatings are often used to protect seeds from environmental conditions, improve seedling establishment, and enhance nutrient availability.

How do seed primers work?

Activation of dormant genes

Seed primers work by activating dormant genes within the seeds. Many seeds have a state of dormancy, which prevents them from germinating under unfavorable conditions. Seed priming treatments help to break this dormancy and trigger the activation of specific genes that are responsible for seed germination and early growth.

Improved water absorption

Water is essential for seed germination, as it initiates the enzymatic processes that lead to cell division and growth. Seed primers improve water absorption by enhancing the permeability of the seed coat and activating mechanisms that facilitate water uptake by the embryo. This allows seeds to effectively absorb water and initiate the germination process.

Enhanced enzyme activity

Enzymes play a crucial role in seed metabolism and growth. Seed primers can enhance enzyme activity by providing specific compounds that stimulate enzyme synthesis and activation. Increased enzyme activity promotes the breakdown of storage reserves within the seed, leading to the release of energy and nutrients necessary for seedling growth.

Delivering essential nutrients

Seed primers can also deliver essential nutrients to the seeds, ensuring that they have an immediate supply of nutrients for early growth. Priming solutions and seed coatings can contain nutrients such as nitrogen, phosphorus, and potassium, as well as micronutrients like zinc and iron. These nutrients are readily available to the seedlings once germination occurs, promoting healthy growth and development.

Inducing stress tolerance

Seed priming treatments can induce stress tolerance in seeds and seedlings. By activating specific genes and metabolic processes, seed primers help plants to better cope with stressful conditions, such as drought, salinity, and disease. This increased stress tolerance allows seeds and seedlings to survive and continue to grow in challenging environments.

Application methods for seed primers

Soaking

Soaking seeds in a priming solution is a common method of applying seed primers. This involves immersing the seeds in a solution containing the desired priming agents for a specific period of time. Soaking allows the priming agents to permeate the seed coat and come into direct contact with the embryo, activating dormant genes and initiating the germination process.

Coating

Coating seeds with a seed primer is another application method. Seed coatings involve applying a thin layer of the priming material onto the surface of the seeds. This can be done using specialized equipment that ensures uniform coverage of the seeds. Coating is often used for large-scale seed treatments, as it allows for efficient and precise application of the seed primer.

Spraying

Spraying priming solutions onto seeds is a convenient method for large-scale treatments. This involves using sprayers or misters to evenly distribute the priming solution onto the surface of the seeds. Spraying allows for quick and uniform application of the seed primer, ensuring that all seeds receive the desired treatment.

Factors to consider when choosing a seed primer
