Summary: This study reports on the influence of testa and endosperm on seed germination of the caper shrub, as well as the effect of gibberellic acid (GA(3)) solutions in breaking seed dormancy. The best germination results were observed with seeds devoid of testa wetted with water and intact seeds wetted with a GA(3) solution. GA(3) addition increased endogenous gibberellin content and the GA/abscisic acid ratio, promoting seed germination. Germination of caper seeds involved testa cracking and endosperm piercing, with puncture force decreasing during imbibition and remaining constant until testa cracking occurred.

Summary: Smyrnium cordifolium Boiss, a biennial medicinal plant, is widely distributed in the Iranian-Turanian phytogeography region. Limited knowledge exists about the seed germination and dormancy of this species. The study revealed that the seeds of S. cordifolium did not germinate after 30 days of incubation at different temperatures, indicating that the seeds were dormant. Increasing the stratification period and temperature regimes had a positive effect on germination. Germination was observed after 4 weeks of incubation at 5 degrees C and peaked at 16 weeks. Darkness and gibberellin concentration also influenced germination.

Summary: The dormancy-breaking requirements and level of morphophysiological dormancy (MPD) were investigated for Ilex formosana, I. uraiensis, and I. rotunda seeds from subtropical and tropical regions of Taiwan. Warm stratification was found to break the shallow simple MPD of I. rotunda seeds. The seeds reached 50% germination after 11-45 weeks of warm stratification at 25/15°C. GA treatment increased the germination rate of I. formosana and I. rotunda (tropical) seeds but had no significant effect on I. uraiensis and I. rotunda (subtropical) seeds. These findings indicate that Ilex species in subtropical and tropical regions of Taiwan have non-deep simple and deep simple MPD, which can be broken by warm stratification. Additionally, GA treatment enhances the germination rate and percentage of Ilex seeds with non-deep simple MPD, while cold stratification promotes the seed germination rate of Ilex species with non-deep simple MPD in the tropical region.

Summary: Nitric oxide (NO) releases dormancy in Avena fatua caryopsis, and its effect depends on the level of dormancy. NO reduces the sensitivity of caryopsis to ABA and decreases the ABA to GA(s) ratio by reducing ABA levels. The levels of GA(s) are not affected by NO before germination is completed.

Summary: Desiccation tolerance is a key adaptation feature of photoautotrophic organisms in terrestrial habitats. Vascular plants have developed complex anatomy structures and molecular mechanisms to maintain cell hydration, with different genes encoding mechanisms playing varying roles in different stages of plant evolution.Mechanisms behind desiccation tolerance include LEA proteins, sHSP, oligosaccharides, and antioxidants, activated during late seed maturation stage. Regulation is controlled by abscisic acid and protein DOG1, along with a network of transcription factors and epigenetic regulation.

Summary: The study identified interactions among starch, sugars, plant hormones, and antioxidant enzymes during bud dormancy release in a low chill peach variety. The changes in abscisic acid and bioactive gibberellins levels were closely related to dormancy release, with a decrease in ABA/GAs ratio being a key factor. Additionally, glucose levels correlated with chill accumulation, peak at ecodormancy and dormancy release, accompanied by increases in antioxidant enzymes.

Summary: Seed germination and dormancy are crucial for the regeneration strategy of plants. This study focused on the dormancy characteristics and regeneration strategies of Clematis hexapetala seeds, revealing deep complex morphophysiological dormancy in freshly matured seeds. Natural cold stratification in winter breaks dormancy and allows the seeds to germinate at the start of the next growing season.

Summary: The timing of seed germination in alpine plants is regulated by dormancy, with seeds needing to germinate early in the spring to ensure seedlings can grow to a critical size during the short growing season. Factors such as burial time and dormancy cycle affect the germination timing and season, with seeds remaining dormant until optimal conditions for growth are met.

Summary: Through studying the seeds of Bunium persicum, we found that the growth of embryos inside the seeds is closely related to the requirements for seed dormancy break and germination. Seeds from different populations of Bunium persicum have varying degrees of physiological dormancy, which are influenced by temperature and the hormone GA3. Seeds developed in cool and wet conditions have a stronger dormancy.

Summary: Appropriate timing of seed germination is crucial for plant survival and agricultural production. Recent studies have shown that ABI5 is a central mediator in the light, abscisic acid, and gibberellin signaling pathways, precisely controlling seed germination. ABI5 is regulated by numerous light-regulated factors at both the transcriptional and protein levels.
