Germination and growth improvement of papaya utilizing oxygen (O2) plasma treatment

In general, cold plasma treatment improves crop germination and growth. The purpose of this research is to examine the impact of low-pressure O 2 plasma treatment on the germination and growth kinetics of papaya seeds. Seeds were treated for 40 s at a discharge power of 80 W using O 2 as a monomer....

Description
Summary:In general, cold plasma treatment improves crop germination and growth. The purpose of this research is to examine the impact of low-pressure O 2 plasma treatment on the germination and growth kinetics of papaya seeds. Seeds were treated for 40 s at a discharge power of 80 W using O 2 as a monomer. Physical and chemical changes were studied to understand the mechanism of germination and growth improvement. Furthermore, changes in phytohormones and antioxidant activity that were beneficial to germination were also examined. O 2 plasma treatment improved wettability, surface etching, and oxidation, and affected other molecular-level changes leading to a 16% germination improvement in papaya.
