Adverse environmental conditions at planting, such as cold temperature or water limitation, can lead to a reduced level of seed germination and plant establishment for cotton. Cold atmospheric-pressure plasma (CAP) treatment of cotton seeds prior to planting may help alleviate this problem. CAP is ionised gas that has a range of biological activities due to the formation of a mix of reactive oxygen and nitrogen species (RONS), excited molecules, charged particles and UV photons. Our results show that a 27 minutes CAP treatment using air can significantly increase water absorption of the seed, and improve warm germination, metabolic chill test germination and chilling tolerance in cotton. We also observe that the beneficial effect of CAP treatment is long-lasting and stable as improved germination activity is still seen when treatment occurs 4 months before germination testing, suggesting that future large-scale industrial seed plasma treatments may still be effectively applied well (months) before the seed planting. We conclude that CAP treatment is a promising new tool for use in the cotton industry that has the potential to significantly improve plant establishment in a wider range of environmental conditions.

“…The unique advantage of using plasmas over other methods of biological stimulation stems from its multi-modal activity, specifically the simultaneous production of chemical species, including reactive oxygen species (ROS) and reactive nitrogen species (RNS) noted for their catalytic activity and biological significance, highly-energetic electrons, electromagnetic radiation and thermal effects, which individually and synergistically affect the treated target 24, 25 . In agriculture, these effects have been exploited to induce stress and thus selectively stimulate seed germination 22, 26 , decontaminate seed surfaces 3 , improve seed disease resistance 27 , and enhance biochemical processes associated with higher crop yields 5 . Of particular value is the ability of plasma treatment to effectively decontaminate the surface of the seed at the same dose as that required to stimulate germination and growth 28 , and without compromising the quality and safety of these seeds as a food source 20 .…”

“…Indeed, despite a number of promising experimental results that demonstrate substantial improvements in seed germination and effective disinfection of seed surface as a result of plasma exposure, the exact identity of chemical species responsible for key events that lead to stimulation of biochemical activity of seed, e.g. changes in its surface physical and chemical properties, and microorganism removal and decontamination, remains a subject of debate 23, 26 .…”

Cold atmospheric plasma has recently emerged as a simple, low-cost and efficient physical method for inducing significant biological responses in seeds and plants without the use of traditional, potentially environmentally-hazardous chemicals, fungicides or hormones. While the beneficial effects of plasma treatment on seed germination, disease resistance and agricultural output have been reported, the mechanisms that underpin the observed biological responses are yet to be fully described. This study employs Fourier Transform Infrared (FTIR) spectroscopy and emission spectroscopy to capture chemical interactions between plasmas and seed surfaces with the aim to provide a more comprehensive account of plasma−seed interactions. FTIR spectroscopy of the seed surface confirms plasma-induced chemical etching of the surface. The etching facilitates permeation of water into the seed, which is confirmed by water uptake measurements. FTIR of exhaust and emission spectra of discharges show oxygen-containing species known for their ability to stimulate biochemical processes and deactivate pathogenic microorganisms. In addition, water gas, CO2, CO and molecules containing −C(CH3)3− moieties observed in FTIR spectra of the exhaust gas during plasma treatment may be partly responsible for the plasma chemical etching of seed surface through oxidizing the organic components of the seed coat.

“…Recently, studies show that cold atmospheric plasma systems could promote seed germination and growth [1,[3][4][5][6][7][8][9][10][11][12][13][14][15]. Increment seed germination rate, growth development, and crop yield by plasma treatment have been reported in various crops: spinach [16], wheat [8,13], soybean [9], and radish [17]. Cold atmospheric plasma systems consist of positively and negatively charged particles (free electrons and ions), and neutral activated species including excited molecules, UV photons, long and short lived free radicals, reactive oxygen species, reactive nitrogen species, and some ozone [18].…”

Recently, cold atmospheric plasma (CAP) with the unique bio-disinfection features is used in various fields of industry, medicine, and agriculture. The main objectives of this work were to design FSG plasma (a semi-automatic device) and investigate the effect of the cold plasma in the enhancement of the Pea and Zucchini seed germination. Plasma irradiation time was studied to obtain a proper condition for the germination enhancement of seeds. The growth rate was calculated by measuring length of root and stem and dry weight of plants treated by plasma. To investigate drought resistance of plants, all treated and untreated samples were kept in darkness without water for 48 h. From the experimental results, it could be confirmed both drought resistance and germination of seedlings increased after plasma was applied to seeds at 30 s, while seeds treated whiten 60 s showed a decrease in both germination rate and seedling growth.
