Summary: The pH-dependent effect of chlorogenic acid (CA) on tall fescue (Festuca arundinacea) seeds was investigated. CA treatments at pH 4 significantly reduced seed germination and related physiological responses, while higher CA concentration led to increased activities of antioxidant enzymes and the induction of a specific peptide. The inhibitory effect of CA on seed germination at pH 4 was in contrast to its stimulating effect at pH 6.8, and pH significantly influenced the activity of CA.

Summary: This study investigated the effect of temperature and light on the germination behavior and early seedling growth of Abies pinsapo seeds from different populations. The results showed that seed origin had a significant influence on germination percentage, while temperature and light had different effects on seeds from different regions.

Summary: The study found that low doses of gamma radiation stimulated seed germination and seedling growth, while high doses significantly affected the growth and physiological indicators of plants. As radiation doses increased, the presence of endophytes in seedlings decreased significantly, indicating that high doses of radiation can impact the viability of endophytes.

Summary: In this study, the effects of ultrasonication treatments on adzuki bean sprouts were examined. The results showed that ultrasonication improved seed hydration, germination, sprout growth and yield, as well as enhanced the nutritional content and antioxidant activity of the sprouts. The treatments at 40 kHz or 80 kHz also effectively reduced microbial loads, making them suitable for adzuki bean sprout production.

Summary: This study investigated the effect of microbial communities on seedling biomass and diversity by seeding pots with native prairie seeds and a non-native competitor. The results showed that inoculating soil with prairie arbuscular mycorrhizal fungi and ex-arable soil increased abundance and diversity of native and late successional plants, leading to decreased abundance of the non-native grass S. faberi.

Summary: The objective of this greenhouse study was to evaluate tall fescue seedling growth when seeded after herbicide application. The results showed that seeding dates after herbicide application did not have a significant impact on growth, but the application of herbicides significantly reduced shoot and root growth. This may have implications for the subsequent growth and development of lawns.

Summary: This study demonstrated that the rice NAC transcription factor OsNAC2 increased ethylene sensitivity in rice roots during the seedling period, delaying seedling establishment by enhancing ethylene synthesis. OsNAC2 also delayed seed germination and coleoptile growth through the ABA pathway, and regulated downstream targets in a time-dependent manner by binding to the promoter of OsKO2 in the seedling period.

Summary: The production of high added value products from bioliquids obtained from the pyrolysis of Tall Fescue waste was studied through catalytic hydrogenation reactions. The optimal pyrolysis temperature was determined through analysis of biomass samples, and bench scale pyrolysis reactions were then conducted. The pyrolysis bioliquids exhibited high furfural concentration, which could be converted into high added value alcohols through catalytic hydrogenation.

Summary: The study demonstrated that ageing has a greater impact on lettuce than cabbage, and pretreatment of seeds with antioxidants enhances seedling growth and performance. The antioxidant treatments promote photosynthesis, protect the photosystems from oxidative stress, and enhance the antioxidant defense system during early development stages of seedlings.

Summary: This study investigated the effects of neodymium on biochemical components, the antioxidant protective system, and metabolism-related enzymes during germination of aged wheat seeds. Soaking seeds in a neodymium nitrate solution can help revive aged seeds by improving germination potential, increasing vigor index, and changing the biochemical composition of seedlings.

Summary: The studies suggest that tall fescue is a low radiocesium-uptake grass with the potential to replace orchardgrass for remediation of contaminated grasslands. Results from two field experiments showed that tall fescue exhibited lower Cs-137 uptake and transfer factor compared to orchardgrass, indicating its ability to reduce potassium fertilizer requirements in contaminated grasslands.

Summary: In this study, the optimal conditions for sunflower seed development were determined, including temperature, water, seed density, and fungal growth. The results showed that temperature significantly affected seed germination and seedling development, with temperatures between 15 and 35 degrees Celsius being optimal. Water availability at 0.6 mL or 125% of the TKW allowed sunflower seeds to germinate. A seed density of 10 to 12 seeds per 9 cm Petri dish showed the best results for future research and breeding projects. Seed priming was found to be a more effective antifungal application technique.
