L-Proline has been shown to have a positive effect on plant growth and development, especially during times of stress. It acts as a biostimulant by improving the plant's ability to cope with environmental stressors such as drought, salinity, and extreme temperatures. Biostimulants are substances or microorganisms that are applied to plants to enhance their growth and development. Biostimulants are not fertilizers or pesticides, but rather they work by improving the plant's physiological processes.The monomeric Amino Acid L-Proline is popular in agriculture nowadays.

What will plants benefit as a Biostimulant from L-Proline?
1. Improves plant growth and yield
L-Proline has been shown to improve plant growth and yield in a variety of crops. It increases flowers setting and fruit setting, as well as the size and weight of the fruits. L-Proline also improves the quality of the fruits by increasing their sugar content and reducing their acidity.
2. Enhances plant tolerance to stress
L-Proline helps plants to cope with environmental stressors such as drought, salinity, and extreme temperatures. It acts as an osmoprotectant, protecting the plant cells from damage caused by water stress. L-Proline also helps to stabilize proteins and other cellular components, preventing damage caused by high temperatures.
3. Improves nutrient uptake
L-Proline has been shown to improve nutrient uptake in plants, especially nitrogen. It enhances the activity of enzymes involved in nitrogen metabolism, resulting in increased nitrogen uptake and assimilation. This leads to improved plant growth and increased output.
4. Increases plant resistance to diseases and pests
L-Proline has been shown to increase plant resistance to diseases and pests. It enhances the activity of enzymes involved in the synthesis of plant defense compounds, for example phytoalexins. This results in increased resistance to fungal and bacterial diseases, as well as insect pests.
5. Environmentally friendly
L-Proline is a natural substance that is non-toxic and environmentally friendly. It does not cause any harmful residues in the water or soil, thus it is a safe Biostimulants Raw Material.
