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: 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: The formation of soil seed banks is crucial for the survival of desert plant species. Stored seeds show higher germination percentages and changed light requirement for germination compared to fresh seeds. Additionally, stored seeds can persist in soil seed banks, offering great potential for maintaining and restoring desert ecosystems.

Summary: This study demonstrates that there is no trade-off between seed persistence and seedling emergence from the soil seed bank. Physically dormant seeds are more persistent but exhibit lower emergence. Monocarpic species have both higher persistence and emergence than polycarpic species. Seed mass has a marginal effect on persistence, while emergence increases nearly twofold from the smallest to the largest seeds.

Summary: Ploidy and species range size or threat status are associated with variation in seed and seedling traits, but their ecological outcomes are not well understood. The study found that polyploids have larger seeds, faster germination rates, and larger and taller seedlings compared to diploids. However, there is no clear relationship between range size and seed or seedling traits. These findings suggest that polyploids have a competitive advantage during the regeneration phase in fire-prone environments.

Summary: The transition from seed to seedling is a crucial step in the plant life cycle. In this study, the authors investigated the changes in water and oxidative status, as well as gene expression, during this transition in Pisum sativum seeds. They found that the accumulation of ROS and the shift in water and oxidative status were correlated with the loss of desiccation tolerance. RNA sequencing analysis revealed differentially expressed genes related to metabolism, photosynthesis, cell wall biosynthesis, redox status, and stress responses. The findings suggest that specific genes, such as LTI65, LTP4, and HVA22E, may play a crucial role in the desiccation tolerance loss during the transition.

Summary: The use of rock dust nanoparticles (RDNPs) as a nanopriming agent can improve seed germination and seedling vigor of native boreal forest species for mine reclamation purposes. Nanopriming techniques show promising results in improving germination percentage (GP) and seedling vigor index (SVI), indicating the potential for enhancing land reclamation using native plants.

Summary: The aim of this study was to investigate the effect of hydrolates obtained from the steam distillation process of Thymus vulgaris essential oil on seed germination and seedling growth. The results showed that the hydrolate had a minimal negative effect on the germination of cultivated species, while weed species showed high susceptibility. It can be concluded that Thymus vulgaris hydrolate has herbicidal potential and can be used as a biopesticide for integrated weed management.

Summary: This study investigated the germination, seedling growth, and vigor of Amaranthus palmeri seeds under different environmental conditions. It was found that temperature, light, moisture, and salt levels had significant effects on the germination and growth of Palmeri amaranth. Additionally, areas with hot and humid climates and low soil salinization had higher risks of invasion by Palmeri amaranth.

Summary: Temperature and water availability are important factors influencing seed germination and seedling development in maize. This study determined the optimal temperature, water supply, and planting density for maize seeds by manipulating factors such as temperature, water levels, and seed size. The results showed that 20 degrees C was the ideal temperature, and water requirements were associated with seed size. Priming seeds with an antifungal solution improved seedling development.

Summary: This study found that light can initiate seed germination of certain species in the soil seed bank when a gap is formed in closed-canopy forests. However, temperature alone cannot trigger seed germination. The combined effect of light and temperature can initiate seed germination of more species.

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 uncovered a molecular network triggered by the plant hormone brassinosteroid (BR) that inhibits the seed maturation program during the seed-to-seedling transition in Arabidopsis, working synergistically with the VAL1/2-mediated pathway to ensure full repression of the seed maturation program. This sheds light on how BR promotes seedling growth by suppressing the seed maturation program.

Summary: The decrease in ground surface height of coastal wetlands is a global concern due to its impact on peat loss, coastal carbon, and freshwater wetland biodiversity. This study investigates the possibility of using long-term changes in the environment and vegetation as indicators for impending transitions of freshwater swamps to other coastal types.

Summary: A long-term study in the Cache River floodplains of Southern Illinois reveals changes in ground height and sediment deposition. The study shows a decrease in the ground heights of certain swamps, potentially due to erosion, increased precipitation, and channel downcutting. These findings have implications for the conservation of natural forests in the area.

Summary: Population projection models based on long-term trends in regeneration and tree survival can be used to predict the future stability of swamp forest species using water management. This study compared the population growth and regeneration of Taxodium distichum, a foundational tree species in North American cypress swamps, in different regional swamps over several decades, and found that moisture gradient, irrigation, and dry conditions had significant effects on population stability and regeneration.
