Summary: Weeds pose a significant challenge to agricultural production due to their adaptability and competitive abilities. The study found that soybean germination was greatly affected by salinity and low temperatures, while maize and rice maintained high germination rates under low salinity levels. Weed species showed varying responses to salinity levels, with some experiencing decreased germination rates. Overall, increasing salinity levels had a negative impact on germination and seedling growth in most species, but higher temperatures partially mitigated these effects.

Summary: This study found that waterbird endozoochory can incorporate seeds into wetland seed banks and delay germination until suitable conditions occur. This has positive impacts on long-distance dispersal and establishment of new populations in wetland plants.

Summary: The study aimed to optimize the germination process of Arthrocnemum seeds using different pretreatments. The results showed that salt priming in darkness at a concentration of 600 mM NaCl improved germination percentages by approximately 25% in both Tunisian and Spanish species. Keeping seeds at different salt concentrations for 30 days produced higher improvement percentages at lower concentrations in A. meridionale (100-200 mM NaCl), while in A. macrostachyum the highest improvement percentages were obtained at 600 mM NaCl (percentage improvement of 47%). Reducing the dark time period to 5 days at higher salt concentrations (800 mM NaCl) resulted in higher germination percentages in all samples, increasing the improvement of germination between 17 and 50%. The optimal conditions for seed germination were found to be pH = 7, pretreatment in darkness at 800 mM NaCl, and 400 μM of iron.

Summary: The study synthesizes the effects of climate change on early life-history stages of high altitude and high latitude plants, highlighting potential impacts on seed germination and seedling establishment. While there is variability in methods and studied species across the literature, the analysis reveals patterns and gaps in knowledge, indicating a need for further research to understand the impacts of climate change on reproductive processes of plants in these environments.

Summary: Temperature and salinity have significant effects on seed germination, but the sensitivity to these factors varies among plant species. Festuca arundinacea is less sensitive to temperature and salinity, while Bromus inermis and Elymus breviaristatus are sensitive to high salinity levels. These findings can enhance our understanding of seed germination in saline soils under changing climate conditions.

Summary: Studies show that precipitation has a significant positive effect on state-level flood damages in the United States, with historical precipitation changes contributing approximately one-third of cumulative flood damages between 1988 to 2017. Climate models indicate that anthropogenic climate forcing has increased the probability of exceeding precipitation thresholds, which are responsible for most flood damages, and that a trajectory consistent with the UN Paris Agreement goals would significantly reduce this intensification of wet conditions.

Summary: This study investigated the effect of different concentrations of NaCl on the germination process of Triticum durum grains, and found that the optimal salinity level for maximizing the production of phytochemicals, particularly phenolic compounds, needs further investigation. The results showed that higher concentrations of NaCl significantly affected germination performance. Salinity induced the accumulation of phenolic compounds in both roots and shoots, with the highest accumulation observed at 200 mM NaCl.

Summary: Soil seed banks play a crucial role in the resilience of communities to global changes. This study found that nutrient enrichment and increased rainfall can significantly impact the composition and diversity of both aboveground and belowground communities. The vulnerability of seed banks to shifts in aboveground communities highlights the importance of understanding the interactions between aboveground and belowground components in grassland ecosystems.

Summary: This study reveals that flooding stress inhibits soybean seed germination by regulating glycometabolism, anaerobic respiration, and phytohormones biosynthesis, which decreases seed vigor and impacts plant growth and development significantly.

Summary: This study investigates the potential role of soil seed banks in different habitats in Europe and finds that high seed bank diversity and compositional similarity with the herb layer may act as a functional buffer against the impact of global environmental changes on plant communities. However, climate warming could threaten this capacity. Dormant life-history stages can be important sources of diversity in changing environments, but their ability to buffer change may only be temporary.

Summary: This study assessed the variation in seed germination among different populations of two desert halophytes and examined the correlation between seed fresh weight and germination. The results showed that the provenance had a significant impact on the germination of Suaeda vermiculata seeds, while the impact was less clear for Arthrocnemum macrostachyum. Additionally, a lower soil pH promoted seed germination.

Summary: Responses to climate change often lag behind warming rates. Soil seed banks can buffer unsuitable conditions, containing species with warm and wide climatic ranges. Seed banks may play a role in climate-driven community shifts and the spread of generalist species.

Summary: This study investigated the effects of different concentrations of exogenous melatonin on the germination and physiological characteristics of rice seeds under flooding conditions. The results showed that the administration of 100 μM melatonin significantly improved seed germination and growth, and alleviated the damage caused by flooding stress by increasing antioxidant enzyme activity and reducing malondialdehyde content. Furthermore, flooding stress treatment and melatonin treatment had a more significant effect on rice seed germination, with the optimal number of days to resist flooding stress being two and the optimal melatonin concentration for seed soaking being 100 μM.

Summary: Seed priming with KNO3 for 20 hours can improve germination and seedling establishment in cotton genotypes under saline conditions. GH-Baghdadi showed higher germination index and final germination percentage. Mean germination time was significantly reduced in both genotypes at 20 hours priming duration with 1.5% KNO3.

Summary: Coastal freshwater wetlands in southeast Queensland, Australia are understudied and vulnerable to climate changes. The study found that vegetation patterns were associated with gradients of rainfall, soil moisture, salinity, and pH. Species composition in the understorey was related to wetland species, native grasses and herbs, and canopy vegetation. Common species like Melaleuca quinquenervia and Eucalyptus tereticornis dominated tree variation.
