Summary: The study determined the optimal temperatures for seed germination of Swietenia macrophylla, with germination rate peaking at 37.3°C and decreasing at ceiling temperature (52.7°C) and base temperature (12.8°C). The thermal time needed for 50% germination was approximately 190°Cd, which could be accumulated in 20 days in the current scenario. The CCSM4 model projected an increase in potential species distribution by 12.3% to 18.3% compared to the current scenario. Temperature plays a crucial role in the seeds' physiological processes and affects their distribution.

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: Salt stress is a significant challenge for crops, and this study investigates the effects of temperature, light, and salinity on the germination and growth of Hibiscus sabdariffa. The findings suggest that 30 degrees C in dark conditions is the optimal temperature for germination, while temperatures below 5 degrees C and above 30 degrees C restrict germination. Increasing salinity reduces germination characteristics, but halopriming can mitigate these effects. The best planting time for Hibiscus sabdariffa is in the spring when temperatures range from 25-35 degrees C. Salt sensitive soils during germination can be improved through halopriming to enhance germination rate and emergence percentage.

Summary: Climate change poses great threats to seed production and sunflower quality in semi-arid regions. Understanding the relationships between agrometeorological, genetic, and agronomic factors is crucial for maintaining crop sustainability. Shifting sowing dates and extending seed-filling periods can improve seed yield and quality, while high temperatures and drought negatively affect seed production.

Summary: The future projection of tropical cyclone frequency is highly uncertain. Recent studies suggest that the spread of seed patterns is correlated with the spread of cyclone patterns. The relationship between seed frequency and climate perturbations can be explained using a downscaling theory.

Summary: This study investigated the effect of elevated carbon dioxide (e[CO2]) on the quality of mungbean seeds, including germination and vigour. The results showed that exposure to e[CO2] did not have a major impact on seed viability, but in one season, there was a slight reduction in seed germination attributed to an increase in hard seeds. However, there were no differences in seed vigour between seeds produced in ambient and e[CO2] environments. Additionally, seeds from e[CO2] had lower protein and sugar content, but higher starch content compared to seeds from ambient [CO2].

Summary: This study used various temperatures and water potentials to investigate the germination response of fenugreek seeds, where the segmented model was found to be the most suitable to describe the germination behavior. Predictions for cardinal temperatures and time constants were also determined for both deteriorated and non-deteriorated seeds.

Summary: Cover crops can suppress weeds through direct competition, allelopathy, or physical barriers. Farmers adopting sustainable farming practices are using cover crops to achieve weed control. Poor and unstable establishment, volunteer cover crops as subsequent cash crops, and seed costs limit cover crop adoption. This study reviews the scientific literature on seed traits to choose suitable cover crops and improve establishment and growth. Seed priming and coating, as well as proper sowing patterns and depth, can enhance cover crop establishment. Different cover crop families exhibit varying germination percentages under water-deficit conditions. Seed dormancy in some Fabaceae species limits their use. The selection of suitable cover crop cultivars is crucial for weed suppression and multiple ecosystem services in the context of climate change.

Summary: Climate change presents challenges for plants due to increased temperature exposure. Phenotypic plasticity plays an important role in plant responses. Different traits show different responses to temperature. Temperature affects plasticity in germination, leaf, physiology, and reproductive traits, and plasticity variation among family lines is related to fitness.

Summary: This study demonstrates that invasive plant Ambrosia artemisiifolia adapts its seed traits in response to climate variations along latitudes and longitudes. Germination time is delayed with increasing latitude and longitude, while germination rate shows a reversed pattern. Temperature is identified as the dominant driver of the variability in seed traits and germination.

Summary: This study evaluated the spatial distribution of human thermal comfort in the state of Sao Paulo, Brazil, based on observed data from 2008 to 2016 and different future climate scenarios. The results showed the regions of greater and lesser discomfort due to cold and heat in the state, for present and future bioclimatic conditions. The study's contributions promote the development of public policies for prevention and adaptation to future climate changes, as well as addressing the increased thermal discomfort at local and regional levels.

Summary: Plant abundance and distribution are regulated by subtle changes in ecological factors under global climate change. This study compared the germination adaptability of two plant species, Halopeplis amplexicaulis and H. perfoliata, and found that H. perfoliata has a wider range of adaptability and tolerance compared to H. amplexicaulis.
