Nano- and Submicrometer Calcium Pectinate Particles as Carriers of Plant Growth Regulators

The calcium pectinate hydrogel particles with an average diameter of 100.0 ± 50.0 nm were synthesized by ionotropic gelation method. The possibility of incorporating of trans-cinnamic acid plant growth regulator into them up to 56.3 wt % was shown. The obtained calcium pectinate particles, including those containing a plant growth regulator, were characterized by transmission electron, atomic force microscopy, and IR spectroscopy. It has been shown that calcium pectinate particles containing trans-cinnamic acid contribute to the accumulation of photosynthetic pigments in the treatment of corn seeds.
