Cold Plasma Poration And Corrugation Of Pumpkin Seed Coats, Alexander G. Volkov, Jewel S. Hairston, Darayas Patel, Ryan P. Gott, Kunning G. Xu Apr 2019

Cold Plasma Poration And Corrugation Of Pumpkin Seed Coats, Alexander G. Volkov, Jewel S. Hairston, Darayas Patel, Ryan P. Gott, Kunning G. Xu

PRC-Affiliated Research

The treatment of seeds and plants by electrically generated cold atmospheric pressure plasma can accelerate seed germination and radicle growing rates. The plasma generated reactive oxygen and nitrogen species, UV photons, and high frequency electromagnetic fields can penetrate into seed coats and modify their surface properties. Atomic force microscope data shows that cold helium or argon plasma induces strong corrugation of pumpkin seed coats, produces pores and surface defects. These structural deformations and poration enhance water uptake by seeds during the imbibing process, accelerate seeds germination, and increase seed growth. The cold atmospheric pressure plasmas treatment of pumpkin seeds also …
