Summary: Seed germination and seedling establishment of Zostera marina L. are significantly influenced by water depth and seed burial depth, with seeds buried at shallower depths in sand showing higher percentages of successful germination and establishment. However, once plants are established, sediment type and burial depth do not play a decisive role in plant growth.

Summary: The transition from seed to seedling is a crucial stage in the life cycle of plants, involving tissue hydration, mobilization of nutrients, and activation of metabolic activity in seeds. This process requires extensive reprogramming of genetic, epigenetic, and hormonal switches, leading to the activation of vegetative growth genes and silencing of seed maturation genes.

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: This study found that cold-tolerant maize varieties have higher germination rates and growth potential under low temperature conditions, with lower hydrogen peroxide content and higher activity of enzymes related to AsA-GSH recycling. Transcription profile analysis revealed increased expression of ZmVTC2 gene in cold-tolerant varieties, suggesting coordinated improvement of AsA biosynthesis and AsA-GSH recycling can increase total antioxidant capacity to alleviate oxidative stress during maize seed germination under low temperature.

Summary: The application of biostimulants is an innovative and promising strategy to improve crop productivity by promoting seed germination. This technique is considered simple, beneficial, and sustainable. However, the mechanisms involved in regulating seed germination and seedling establishment by non-microbial biostimulants are still unclear.

Summary: Seagrasses globally decline and restoration efforts face challenges, such as predation by macroinvertebrates. The study investigates how common ragworms may act as predators on eelgrass seeds, hindering seed-based restoration. Experimental findings show that high ragworm biomass can completely hamper seedling establishment, indicating a potential bottleneck for restoration efforts. Furthermore, the study reveals that ragworm infestations overlap with potential eelgrass growth sites, highlighting the significance of this finding for restoration efforts.

Summary: This study identified and analyzed ZmAQPs and determined their expression patterns during seed germination and early seedling development. It found that ZmTIP3-1 improved seed vigor and played a positive role in seed germination and seedling growth. These findings provide valuable insights into the function and regulation of ZmAQPs.

Summary: To maximize the potential of seagrass as a nature-based solution, large-scale restoration is needed. This study investigated the success of planting seagrass seeds using various treatments. The results showed that the addition of nutrients to sediment can improve seagrass shoot emergence and growth. However, the study also highlighted the variability in planting methods and the need for further research in seagrass restoration.

Summary: Karrikins (KARs) are small butenolide compounds found in burning vegetation smoke, with stimulating effects on seed germination and regulation of seedling growth and adaptive behaviors. The SMAX1 signaling repressor plays central roles in these processes, integrating multiple growth hormone signals to optimize seedling establishment. This article summarizes the versatile roles of SMAX1 and discusses the evolutionary relevance of the SMAX1-mediated signaling pathways during the colonization of aquatic plants to terrestrial environments.

Summary: Climate change can impact tree recruitment by affecting post-dispersal seed fates and impairing seedling development. Seed biomass plays a crucial role in tree recruitment processes, especially in harsh environmental conditions. The study findings suggest that climate change may alter seed-parasite interactions and favor larger seeds over smaller seeds during the recruitment of certain tree species.

Summary: The use of seed- and shoot-based restoration approaches for Z. muelleri in Victoria, Australia was explored through field trials. Seed collections and germination achieved good results, with seed collection rates improving from 489 to 1,939 seeds/hour over 2 years and in situ seedling germination rates increasing from a maximum of 10.80% to 25.25% over 2 years. In contrast, shoot-based restoration approaches were more variable, with plants transplanted with their sediment-intact outperforming all bare-rooted approaches. Seed-based approaches have the potential to be viable and scalable for Z. muelleri, but further studies are needed to improve seedling survival and in situ germination rates.

Summary: BPS can impact plant growth and community structure, especially in coastal restoration areas. The study in the Yellow River Delta of China highlighted the importance of biogeomorphological structures, such as concave hollows from crab burrowing and around plant roots, in trapping seeds and influencing seedling establishment. Creating artificial concave hollows also proved beneficial in facilitating seedling establishment.

Summary: A mechanistic model was developed to assess the removal efficiency of pollutants in a wetland system, particularly in oil sands process-affected water (OSPW). The model simulated wetland mechanisms of chemical removal and showed that sustained wetland treatment is feasible. It is a helpful tool to evaluate the feasibility of treatment systems and to assess trade-offs in wetland design and operation.

Summary: The Everglades Stormwater Treatment Areas (STAs) are constructed wetlands built to remove phosphorus (P) from agricultural and urban runoff in support of Everglades restoration. Research shows that the levels of calcium (Ca) and alkalinity (Alk) have an impact on phosphorus removal in these wetlands.

Summary: This study examined the long-term phosphorus retention in Stormwater Treatment Areas (STAs) and identified the factors influencing their performance. The results showed that the operational performance of STAs improved over time. There were notable differences among individual STAs, with the co-precipitation of phosphorus with calcium playing a critical role in one of the STAs. This highlights the complexity of phosphorus removal in STAs and the need for site-specific management strategies.

Summary: The biogeochemical response to different flow conditions within two parallel flow-ways in Everglades Stormwater Treatment Area (STA)-2 was studied. It was found that there was a gradual decrease in the total phosphorus (TP) concentration from inflow to outflow for both emergent aquatic vegetation (EAV) and submerged aquatic vegetation (SAV) dominated systems, with EAV showing a higher reduction rate. Significant increase in TP concentration was observed in the SAV system under no flow condition, possibly due to the production of particulate phosphorus (PP) through various mechanisms.
