Abstract Applying cold discharge plasma can potentially alter plants' germination characteristics by triggering their physiological activities. As a main crop in many countries, soybean was examined the present study using cultivars such as Arian, Katoul, Saba, Sari, and Williams argon plasma. This has been motivated importance of plant production worldwide, considering climate change increasing needs human populations for food. performed to inspect effect treatment on seed impact microbial decontamination investigated soybeans. Also, employed have not studied until now radicals generated from were detected optical emission spectrometry (OES), collisional radiative model used describe electron density. The properties, including final percentage (FGP), mean time (MGT), root length, electrical conductivity biomolecules released seeds, after treatments 30, 60, 180, 300, 420 s. Aspergillus flavus (A.flavus) Fusarium solani (F.solani) also examined. 60 s induced maximum FGP 23.12 ± 0.34% lowest MGT value 1.40 0.007 days. Moreover, ultimate length 56.12 2.89%, seeds treated exposure, however, failed yield significant enhancement conductivity, even when duration extended 180 or longer. Therefore, selected blotter technique. Both fungi showed successful sterilization; infectivity inhibition 67 4 65 3.1%, respectively. In general, soybeans preserved healthy qualities reduced degree fungal contamination.

Micro-greens or sprouts are commonly used in the diet of many cultures owing to their health benefits. In this work we use a non-chemical solution method stimulate germination and growth seeds for sprouting, based on non-thermal plasma discharge (NTP). Such technology could represent an alternative not only reducing production costs growing micro-greens but also as pre-sowing slow germinating species those under draught stress. To evaluate efficiency treatments, Brassica oleracea Lepidium sativum were exposed produced atmospheric air different conditions.

Effects of Seed Processing with Cold Plasma on Growth and Biochemical Traits of Stevia rebaudiana Bertoni Under Different Cultivation Conditions: In Soil Versus Aeroponics

Plants, Journal Year: 2025, Volume and Issue: 14(2), P. 271 - 271

Published: Jan. 18, 2025

This study compared the effects of seed treatment with low-pressure cold plasma (CP) and atmospheric dielectric barrier discharge (DBD) on morpho-biochemical traits in Stevia rabaudiana Bertoni plants cultivated by two methods: soil aeroponics. We investigated impact treatments germination, plant growth, content secondary metabolites, namely steviol glycosides (SGs), rebaudioside A (RebA), stevioside (Stev), as well phenolic compounds flavonoids. Seeds were treated for 2, 5, 7 min CP or DBD 5 vacuum six days before sowing. All growth parameters aeroponics exceeded seedlings corresponding groups soil. Seed stimulated SGs biosynthesis grown soil, except CP7. Although there no stimulating aeroponics, overall SG concentrations considerably higher to soil: RebA+Stev concentration was 1.8–2-fold control, V5-, CP-treated groups, 1.3-fold DBD5 DBD7 groups. Thus, aeroponic cultivation has potential improve synthesis stevia, while a combination only increases antioxidants antioxidant activity.

Stevioside (Stev) and rebaudioside A (RebA) are the most abundant steviol glycosides (SGs) responsible for sweetness of Stevia rabaudiana Bertoni. As compared to Stev, RebA has a higher sweetening potency, better taste therefore is preferred component stevia leaf extracts. The aim this study was determine effect pre-sowing seed treatment with abiotic stressors cold plasma (CP) electromagnetic field (EMF) on amount ratio Stev in leaves stevia. Additionally, total phenolic content, flavonoid content antioxidant activity investigated. Seeds were treated 5 7 min (CP5 CP7 groups) 10 (EMF10 group) six days before sowing. germination tests vitro demonstrated that all treatments slightly increased rate percentage. HPLC analysis revealed CP EMF had strong stimulating SGs accumulation. All concentration approximately 1.6-fold; however, RebA/Stev decreased from 8.5 control 1.9, 2.5 1.1 CP5, EMF10 groups respectively, since more than RebA, 7.1, 4.6 11.0-fold, control.
