Plasma Applications on Algriculture

I. Plasma-Activated Water (PAW)
(1) Doubled Chlorophyll
Leaf chlorophyll levels doubled in treated tomato plants
(2) +61% Wet Weight
Overall plant wet weight significantly increased vs. control group
(3) Sustainable Fertilizer
Chemical-free, enriched with reactive oxygen and nitrogen species

II. Seed Treatment
(1) Cotton Seeds — Cold Germination
Plasma treatment doubled germination rates under cold test conditions, demonstrating enhanced seed vigor and wettability.
(2) Soybeans — Nodule & Nitrogen
Fresh nodule biomass increased by 72%; nitrogenase activity boosted by 1.6-fold, improving biological nitrogen fixation.

III. Post-Harvest Preservation
(1) Vanda orchid
PAW-nitrate extended Vanda orchid vase life 12.63d
(2) Strawberry Bacteria
Aerobic bacteria & mold reduction 3 log
(3) Melon Lactobacilli
Reduction in fresh-cut melons 7 log

IV. Enhanced Extraction of Essential Oils
(1) Lemon Peel Oil 149%
Essential oil yield increase vs. microwave extraction
(2) Lemon Verbena 36.7%
Oil increase within 1 minute of treatment

Plasma-activated Water

Applying 30-minute plasma-activated water to tomato plants not only doubled their leaf chlorophyll levels but also significantly increased the overall plant wet weight by 61% over the control group.

Seed Treatment

Plasma treatment doubled cotton seed germination rates in cold tests. For soybeans, it increased fresh nodule biomass by 72% and boosted nitrogenase activity by 1.6-fold.

Enhanced Extraction

Cold plasma treatment increased lemon peel essential oil yields by an impressive 149.34% compared to microwave extraction. Lemon verbena essential oil content rapidly increased by 36.7% within just one minute of treatment.

Post-Harvest Preservation

Cold plasma and activated water extend the vase life of cut flowers. In-package plasma treatment of strawberries reduced aerobic bacteria and mold by ~3 log cycles. For fresh-cut melons, Lactobacilli decreased by up to 7 logs.
