Cold Radiofrequency Plasma Treatment Modifies Wettability and Germination Rate of Plant Seeds

The incorporation of native plant species is central to restoration efforts, but this is often limited by both the availability of seeds and the relatively low viability and germination rates of commercially available seeds. Although pre-sowing treatments are commonly used to improve germination rates of seeds, the efficacy of these treatments is found to vary across species. In this study, we tested how four pre-sow treatments (physical scarification, acid scarification, cold stratification, and aerated hydropriming) affected the viability and seed germination rates of 12 commercially available plant species native to south Texas and commonly used in restoration efforts. Our results show that the viability of the seeds have a wide range, from 78% to 1.25%. Similarly, the total germination rate ranged from 62% to 0%. We found that pre-sowing treatments accelerated the germination rate in 9 of 12 plant species tested, but the effect varied by treatment. Collectively, our results identify various methods to achieve the best germination rates for native plants of south Texas, to help improve restoration efforts across the region.

Abstract. Zairina A, Mondiana YQ. 2020. The effect of slope level and hydroseeding formula on the growth of Cyperus brevifolius and Pueraria javanica seedlings. Biodiversitas 21: 5008-5012. The aim of this study was to analyze the effect of the slope level on the growth of green kyllinga (Cyperus brevifolius) and puero (Pueraria javanica) seedling in a hydroseeding formula. The hydroseeding mixture consists of plant seeds, compost, soil conditioner, manure, and water. In addition, to all hydroseeding compositions, guar gum and a local microorganism mix were mixed until colloidal mulch was obtained. This study applied factorial design with slope level dan hydroseeding treatment as independent variables, while seed height, number of shoots, and number of leaves were the dependent variables. Data were replicated four times. The hydroseeding formula had a significant effect on all variables, except for the height of C. brevifolius seedlings. There was a significant interaction effect between the slope level and hydroseeding treatment on the germination rate of both species but the effect of this interaction was not significant on plant height and leaf number. The best germination rates were found in boxes with a slope of 100%. This situation was consistent for both species. This indicated that both species had the potential to be used as pioneer plants in post-landslide reclamation with a slope of 100%.

Abstract Plasma agriculture is an emerging technology, although the application of non-thermal plasma in wheat productivity is still in its early stage. This study deciphers the effect and mechanistic basis of non-thermal air-generated LPDBD (low-pressure dielectric barrier discharge) plasma in boosting germination, growth and nutritional properties in wheat. Seeds treated with LPDBD plasma exhibited cracked periphery and 6 min treatment showed a 22.11% increase in the germination rate compared to non-treated controls. At the cellular level, the concentration of H2O2 in leaves significantly increased (3.56 µM g-1FW) due to LPDBD plasma treatment, may act as a stimulating agent to trigger the physiological functions in wheat plants. In addition, plants sprouted from air-treated seeds exhibited a marked elevation in CAT and SOD activity accompanied by the increased expression of TaCAT and TaSOD genes in roots of wheat. Interestingly, the grain yield of wheat increased by 27.06% in response to plasma treatment compared to control. Further, grains harvested from plasma-treated plants showed a substantial elevation in iron and fat content as well as decreased moisture content that may contribute to the increased shelf life. The study will open up a new avenue for practical application of plasma in agriculture.

Significant Attention

Cold plasma technology has received significant attention in agriculture due to its effect on the seeds and plants of important cultivars, such as wheat. Due to climate change, wherein increasing temperatures and droughts are frequent, it is important to consider novel approaches to agricultural production. As increased dormancy levels in wheat are correlated with high temperatures and drought, improving the germination and root growth of wheat seeds could offer new possibilities for seed sowing. The main objective of this study was to evaluate the influence of direct (glow) and indirect (afterglow) radio-frequency (RF) oxygen plasma treatments on the germination of two winter wheat varieties: Apache and Bezostaya 1. The influence of plasma treatment on seed surface morphology was studied using scanning electron microscopy, and it was observed that direct plasma treatment resulted in a high etching and nanostructuring of the seed surface. The effect of plasma treatment on germination was evaluated by measuring the germination rate, counting the number of roots and the length of the root system, and the fresh weight of seedlings. The results of this study indicate that the response of seeds to direct and indirect plasma treatment may be variety-dependent, as differences between the two wheat varieties were observed.

Ionized Gas

Plasma also called as ‘fourth state of matter’ encompasses ionized gas, atoms, free molecules, radicals and free electrons. Considering its discovery in late 19th century plasma is extensively used as low pressure or high pressure plasmas in many applications commercially such as microelectronic technology, textile industry, organic waste management etc. When a gas is passed through an electric field in a plasma chamber, three types of collisions are known to take place in it particularly, excitation, ionization and deposition that provide plasma its characteristic glow, ion-electron pair, reactive species respectively. Plasma treatment of different object can change their chemical and physical properties. In Seed Science and Research, many seed quality enhancement techniques are used to improve seed quality in crop plants such as, seed priming, fortification, solid matrix priming, chemical treatment, hardening etc. Plasma treatment of seeds is a unique tool that utilizes an ionized gas to modify the physical and chemical properties seed viz., wettability, porosity, water absorption, activity of antioxidant enzymes. It can also decontaminate the seed surface off micro flora and convert hydrophobic seeds to hydrophilic. It also enhances soluble sugar content, protein content and causes a reduction in lipid peroxidation. Thus plasma treatment in turn improves seed germination rate, seedling characteristics, seed physical quality and seed health.
