Phycocyanin is a pigment found in blue-green algae, including the species Spirulina platensis, which is known for its high concentration of this pigment. It is a water-soluble protein that has been found to have positive effects on plant growth and development.
A study published in the Journal of Applied Phycology in 2016 found that when phycocyanin was applied to tomato plants, it led to an increase in the number of leaves, branches, and fruits, as well as an increase in the chlorophyll content of the leaves.
Another study published in the Journal of Plant Interactions in 2018 found that when phycocyanin was applied to wheat plants, it led to an increase in plant growth and biomass, as well as an increase in the protein content of the grains.
A study published in the Journal of Plant Growth Regulation in 2018 found that when phycocyanin was applied to lettuce plants, it led to an increase in the antioxidant content of the leaves and improved plant tolerance to salt stress.
It's important to note that the optimal concentration of phycocyanin for plant growth depends on the plant species, growth stage, and environmental conditions. It's best to consult with a professional agronomist for more information.
