Summary: The study revealed that various polymer types in the Arabidopsis seed coat provide protection against chromium (Cr3+) toxicity through different mechanisms and degrees. Suberin was identified as the main physical barrier against Cr3+ toxicity. The results also emphasized the risks associated with Cr3+ toxicity on the persistence of seeds with relatively low seed coat suberin in soils contaminated with high levels of chromium.

Summary: This study investigated the effect of seed color on the germination and growth of alfalfa under salt stress. The results showed that brown seeds had significantly lower germination and seedling performance compared to green and yellow seeds. Yellow seeds exhibited higher vigor. Factors such as water uptake rate and hormone content may have contributed to the differences in stress resistance among seed colors.

Summary: The domestication process of legume seeds has resulted in altered dormancy patterns, leading to faster and more uniform germination compared to wild progenitors. By studying the physiological and anatomical aspects of seed dormancy, significant differences were observed between cultivated chickpeas and wild progenitors, providing insights into potential molecular mechanisms of seed dormancy in chickpeas.

Summary: Understanding the germination pattern and seed longevity of Echinochloa colona in field conditions is crucial for effective weed management. The study found that the populations of E. colona exhibited innate dormancy, with some seeds capable of germinating in the next season. The research also indicated that seed persistence and germination patterns of E. colona can vary with different soil and agro-climatic conditions.

Summary: The sunflower seed dormancy is regulated by the interaction between the one-layered endosperm, seed coat, and embryo, and the levels of ABA, JA, and IAA in these tissues. The release of dormancy is associated with increased ABA and JA levels in the seed coat and endosperm, but decreased levels in the embryo. The anatomy of the seed coat and one-layered endosperm showed no significant differences between lines. The findings highlight the importance of hormone metabolism and tissue interactions in the release of sunflower seed dormancy.

Summary: This study found that the proportion of water-impermeable seed coats (physical dormancy) in Fabaceae seeds increases with the dryness of the habitat. It also discovered that species with non-dormant seeds have lower seed coat:seed mass ratios and higher seed shape index values compared to species with physical dormant seeds.

Summary: The study aimed to investigate whether radicle emergence (RE) is correlated with storage potential of watermelon seed lots. Results showed that measuring RE percentage between 34-60 hours after germination is highly correlated with seed survival after 63 days of storage at 25 degrees Celsius

Summary: The study found that under water stress conditions, brown-seeded families had significantly higher heritability and genetic advance for seed yield compared to yellow-seeded families. Additionally, while yellow-seeded families had higher SDG content in non-stress environments, brown-seeded families showed an increase in SDG content under water stress conditions.

Summary: The processes of seed water absorption and germination are crucial for plant seedling establishment. Our study found that low levels of tetracycline (TC), a commonly used antibiotic, have negative effects on the seed water absorption and germination of Chinese cabbage and edible rape seeds.

Summary: Seed germination and subsequent seedling growth of alfalfa are not significantly affected by vanadium concentrations up to 10 mg L-1 V, however, root vitality and elongation are inhibited at concentrations of 0.5 mg L-1 V or higher. Accumulation of vanadium in the testa is beneficial for alleviating its toxicity to seed germination, while leaf proline content significantly increases at concentrations of 0.5 mg L-1 V or higher. Alfalfa shows potential for phytoremediation in vanadium-contaminated environments within determined thresholds.

Summary: The widespread use and mishandling of plastics have led to severe environmental issues, impacting seed germination and seedling growth. This study used Biospeckle Optical Coherence Tomography (bOCT) to investigate the effect of polyethylene microplastics (PEMPs) on lentil seed germination and seedling growth. The results showed that PEMP presence significantly reduced internal activity during the initial stages of germination.

Summary: Global change and environmental pollution have raised the alarm for ecologists about the significant threat of multi-stress interactions to plant growth stages. This research focused on the effects of sand burial, salinity, drought, and their interactions on the germination of Sophora alopecuroides L. seeds. The results showed that sand burial and salinity stress had significant effects on seed germination, while drought stress had no significant effect, but the interaction of the three stresses had a significant effect. The study also found that sand burial stress was the most limiting factor for seed germination, and moderate increase in soil saline-alkali content and soil moisture could improve germination ability.

Summary: Parthenolide disrupts the expression pattern of COP1 and cold responsive genes, reducing freezing tolerance of hydrated seeds by affecting protein degradation pathways. The inhibition of proteolysis and reduction of molecular chaperons in parthenolide-treated seeds may contribute to the decrease in freezing tolerance of hydrated seeds. Further research on the molecular mechanisms involved in this process is needed.

Summary: The study reveals that some Arecaceae species exhibit both dormancy and desiccation sensitivity, which could impact their germination ecology. The ecological significance of this relationship in tropical forests is currently unknown, calling for further research in germination ecology focusing on dispersal and burial.

Summary: The impermeable pericarp of recalcitrant acorns in temperate oak species plays a crucial role in preventing the drying of the embryo axis, but its effectiveness depends on moisture content. Factors such as acorn anatomy, moisture content, microhabitat, and position in the soil can influence the survival of acorns during winter in temperate regions. However, in-situ experiments are needed to test the hypothesis that survival also depends on continuous erratic rainfall.

The results showed that the acorns are non-dormant and have high recalcitrance. Moreover, the study revealed the development of a tubular structure during germination, which requires further investigation for its ecological significance.

Summary: Seeds with physical dormancy (PY) dominate dry tropical forests. This study reveals that the moisture content and temperature play crucial roles in the preconditioning and 'water-gap' opening stages of PY. High temperature breaks PY in seconds, while seasonal temperature fluctuations and constant temperatures require a longer time. The moisture content of seeds and its interaction with biochemical compounds may explain why only a portion of PY seeds become permeable each year.
