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: Certain substances called germination inhibitors can inhibit the germination of seeds. They can be classified as germination destructors or germination retarders, with the former causing harm to the seed and the latter being closely related to seed dormancy. These inhibitors have important applications in seed preservation and herbicide use.

Summary: This study investigated the mechanisms underlying interspecific differences in seed thermotolerance in desert Cactaceae species. It was found that enhanced dry seed thermotolerance is realized through enhanced recovery from heat stress during imbibition, particularly during critical stages in the plant life cycle. The study highlights the importance of heat-responsive gene expression patterns in contributing to higher dry seed thermotolerance in extremophile Cactaceae species.

Summary: This study investigated the effect of nitrogen fertilization on tomato seed yield and quality. The results showed that increasing nitrogen fertilization led to a decrease in seed weight, but had no effect on standard germination and mean germination time. The germination percentage and rate decreased when seeds were immersed in solutions with reduced osmotic potential, but this effect was less pronounced in seeds from the high nitrogen treatment. Additionally, seeds from the high nitrogen treatment exhibited greater longevity when evaluated after accelerated aging.

Summary: This study focused on breaking the seed dormancy of Dracaena steudneri Schweinf. Ex Engl. seeds using different presowing treatments. However, the results showed that the treatments did not improve the germination rates of the seeds. More research on the seed ecophysiology of this species is recommended.

Summary: The recovery of dryland plants after wildfire is uncertain and fire legacies have long-lasting effects on aboveground plants. However, our knowledge of how fire impacts soil seed banks and their succession is limited. To address this, we studied soil seed bank changes 15 and 30 years after wildfire in four North American deserts. We found that warm desert sites had seed banks dominated by annual plants while cold desert sites had greater proportions of perennial species, regardless of fire history. Fire significantly altered seed bank species composition in cold desert sites even after 30 years. Microsites had no observed influence on seed bank composition in any desert. Non-native species were present in all deserts' seed banks, suggesting vulnerability to future disturbances.

Summary: Seed banks are crucial for population survival in highly variable environments, and the response of desert species' seed banks to climate change is a key concern. The rare desert plant Arctomecon californica has shown a remarkable ability to maintain a long-lived seed bank, with up to 20 years of seed viability. Protecting known population areas is crucial for the conservation of this species' seed bank.

Summary: Seed quality and moisture content affect the germination of Cardiospermum halicacabum seeds, with seeds with water-impermeable seed coats showing different responses in different climatic zones. Seeds from DZ and WZ1 showed higher imbibition rates compared to WZ2 seeds, indicating that scarified seeds are more likely to germinate.

Summary: The ability of weed seeds to survive and emerge from different soil textures and burial depths is influenced by factors such as soil texture, seed weight, and the maximum hypocotyl elongation. The inhibitory effects on seed emergence are found to be more pronounced in clay soil compared to sandy soil. Evaluating the performance of buried seed banks in different soil textures can help improve the forecast models of emergence dynamics and lead to more rational and sustainable weed management practices.

Summary: The germination of Paeonia ostii seeds is dependent on a warm-cold-warm temperature sequence, with warm stratification breaking physiological dormancy of the embryo and cold stratification breaking dormancy of the epicotyl. The results indicate that P. ostii seeds have morphophysiological dormancy.

Summary: A model that simulates seasonal dormancy changes in buried Arabidopsis thaliana seeds can accurately predict germination in a realistic global warming scenario by analyzing changes in the thermal range permissive for germination. The study reveals the importance of understanding how the environment regulates seed-bank dormancy changes for predicting seedling emergence and interpreting dormancy mechanisms.

Summary: The study found that Agave striata and Agave salmiana have different mechanisms for tolerating drought and varying shade conditions. Agave salmiana showed increased carotenoid concentration with decreasing shade levels, while Agave striata exhibited significantly decreased pigment concentrations under drought conditions. Additionally, drought reduced water potential in Agave striata but not in Agave salmiana, indicating species-specific responses to stressors.

Summary: The aerenchyma in mangrove stem bark allows gas flow into the roots through a network of gas spaces, with variations in structure between Rhizophora mangle and Avicennia germinans. Both species exhibit honeycomb-like aerenchyma in the lower stem level, contributing to resistance against internal pressure. They have developed common functional adaptations for living in temporary anaerobic root environments.

Summary: Recent studies show that warming has negative effects on the physiological performance of plants, but the extent of these effects depends on the thermal tolerance of each plant species. Despite the increasing global demand for oats, there is limited research on the warming effects on oat ecophysiology and biomass production. This study used induced warming experiments to evaluate the impact of warming on oat ecophysiology and biomass production.

Summary: Viviparous cactus seedlings develop larger and wider wide-band tracheids (WBTs) and vessel elements under water deficit stress, indicating more efficient water conduction compared to non-viviparous seedlings. This adaptation increases the survival chances of Echinocactus platyacanthus populations and contributes to their natural regeneration in arid environments.
