Aluminate flocculants are employed widely in water treatment for precipitating suspended solids and emergency treatment of algal blooms in eutrophic lake, but the residual aluminum (Al) may have phytotoxic effects on aquatic organisms after entering aquatic ecosystems. To elucidate the potential impacts of Al on turion germination and early growth in Potamogeton crispus , we conducted a mesocosm experiment using five Al concentrations (0 (control group), 0.3, 0.6, 1.2, and 1.5 mg/L) in alum solutions. The results showed that the germination of turions and the early growth of P. crispus were reduced and inhibited by Al. The maximum numbers of germinating turions and newly-formed seedlings occurred in the control group, and their numbers declined in the end of the experiment as the Al concentration increased. Al at a concentration of 1.5 mg/L decreased the number of germinating turions 3.0 times and the number of newly-formed seedlings 30.7 times compared with the control. The chlorophyll content and root activity decreased when the Al concentration increased. The maximum soluble protein contents in seedling tissues (1.953 mg/g fresh weight) occurred in the 0.6 mg/L treatment group, which differed significantly from the other treatment groups. The Al contents in the seedling tissues had a significant positive correlation with the Al treatment concentrations ( P < 0.05, r = 0.763), but negative correlations with the biomass, root number, stem weight, soluble protein, and root activity (r = −0.935, −0.975, −0.907, −0.721, −0.944, respectively). Persistent Al concentration ≥1.2 mg/L significantly decreased the germination of turions and seedling growth in P. crispus . These results may facilitate the restoration of aquatic macrophytes and ecological risk assessments in Al-exposed lakes.

As a persistent organic pollutant in the environment, perfluorooctanoic acid (PFOA) has been extensively investigated. It can accumulate in food chains and in the human body. This work investigated the effect of PFOA on wheat ( Triticum aestivum L.) germination and seedling growth by conducting a germination trial and a pot trial. A stimulatory effect of PFOA on seedling growth and root length of wheat was found at <0.2 mg kg −1 , while >800 mg kg −1 PFOA inhibited germination rate, index, and root and shoot growth. In the pot trial, PFOA concentration in root was double that in the shoot. Soil and plant analyzer development (SPAD) and plant height of wheat seedling were inhibited by adding 200 mg kg −1 PFOA. Proline content and POD activity in wheat seedlings increased as PFOA increased, while CAT activity decreased. Using logarithmic equations, proline content was selected as the most sensitive index by concentration for 50% of maximal effect (EC 50 ). Hence, the tolerance of wheat seedlings to PFOA levels could be evaluated on the basis of the physiological index.

To improve the conventional germination process and improve the nutritional quality of red kidney beans , this study employed high-intensity ultrasound (HIU) supplemented with hydrogen peroxide as a pre-germination treatment. The results showed that the 350 W-10 min treatment yielded the highest germination rate (77.09%), with its sprout length 81.13% greater than that of the control group. The 350 W-10 min treatment increased total protein, soluble protein, and ash content, while simultaneously reducing the fat, starch, and soluble sugar content. The HIU treatment accelerated the accumulation of phenolic and flavonoid compounds, ascorbic acid , and γ-aminobutyric acid. The 350 W-10 min treatment also decreased the levels of phytic acid , trypsin inhibitor activity, and tannin by 42.71%, 65.58%, and 53.18%, respectively. Furthermore, ultrasonic cavitation enhanced antioxidative capacity and improved amino acid composition and protein digestibility . Consequently, HIU serves as a cost-efficient method to accelerate the germination process and enhance their nutritional composition.

Zea mays (Maize) is prone to mildew due to its rich nutrition and large embryo, resulting in the decline of edible quality, germination rate and even threatening people's health. In this study, ZnO nanoparticles were prepared by hydrothermal method to inhibit the growth of microorganisms on the surface of Zea mays . For its safe and efficient application, mesoporous silica (mSiO 2 ) was modified on its surface and successfully prepared ZnO@mSiO 2 Nanocomposites. The ZnO@mSiO 2 nanocomposites were successfully prepared and characterized by TEM, EDS, XRD, FT-IR, and it could significantly inhibit two model bacteria and three model fungi. After mixing with Zea mays and 42 days of simulated storage, they could significantly inhibit the growth of microorganisms in Zea mays , ensure the stability of Zea mays quality and improve the germination rate of Zea mays . The ZnO@mSiO 2 nanocomposites prepared in this study provide a new idea for the safe storage of Zea mays .

The present work aimed to investigate the effect of plasma-activated water (PAW) on seed germination and seedling growth of mung bean sprouts. Distilled water was exposed to non-thermal plasma for 15, 30, 60, and 90 s to prepare PAW, which was defined as PAW15, PAW30, PAW60, and PAW90, respectively. The germination rate, growth characteristics, total phenolic and flavonoid contents were all maximized when mung bean seeds were treated by PAW15, then followed by a decline over the prolonged plasma activation time (30–90 s). PAW15 caused no remarkably changes in the antioxidant capacity of sprouts as compared to DW (p > 0.05). However, the antioxidant activity of sprouts prepared with PAW30, PAW60, and PAW90 were decreased significantly (p < 0.05) compared with that of sprouts soaked in distilled water. In summary, PAW may be used to improve the production of sprouts, but the process parameters should be optimized for each application.

Plant biostimulants (PBs) are a potential strategy to improve crop growth and grain quality. In the present study, 100 mg/L trehalose, chitosan, humic acid and gamma-aminobutyric acid treatments were applied to analyze the effects of maize production and reproductive characteristics. The contents of nitrogen, phosphorus and potassium and grain quality were significantly affected by the PBs, but not yield. The seed germination rate of all PB treatments was significantly reduced, but the drought resistance of progeny seedlings was significantly improved, with humic acid having the strongest effect. Liquid chromatography mass spectrometry analysis indicated that the disruption of the tricarboxylic acid cycle, probably due to the blockage of intermediate anabolism, reduced the supply of energy and nutrients in the early stages of germination, thus inhibiting seed germination, while the increased resistance of the offspring seedlings may be due to the up-regulation of the synthesis of unsaturated fatty acids and alkaloids by humic acid treatment. This study revealed the similarity and heterogeneity of the effects of different PBs on nutrient accumulation, yield characteristics and grain quality of maize, providing guidance for the application of PBs in intensive and sustainable agricultural production.
