Abstract: Elucidating the physiological and ecological mechanisms of seed dormancy germination is great significance for species conservation application plant resources. Based on Baskin Baskin’s classification system dormancy, cause in Tarenaya hassleriana (Cleomaceae) seeds was studied using alternating temperature, cold moist stratification, dry storage, GA3 soaking treatment. The results in...

Abstract Seed dormancy ensures seedling establishment in the favorable season a seasonally changing environment. Korean pine (Pinus koraiensis Sieb. et Zucc.) seeds have morphophysiological after dispersal autumn. A small fraction of germinates first spring, but most germinate second spring following dispersal. It is not clear how status changes and thus drives germination characteristic. Fresh...

Abstract Background Euphorbia jolkinii Boiss. is a perennial species native to Jeju Island and the southern coastal area of Korea. Particularly on Island, yellow flowers E. have high ornamental value because their contrast with basalt. This study was conducted investigate effects different temperatures (5, 15, 20, 25 °C) gibberellic acid (GA 3 ) concentrations (0, 10, 100, or 1000 mg/L) seed do...

Knowing the determinants of seed germination helps us understand plant adaptive strategies to environment and predict population community regeneration under climate change. However, multiple factors, including traits that influence their relative importance, have received little attention. Here, experiments were conducted on newly collected seeds for 89 herbaceous species from salinized Songne...

Germination inhibitors, which inhibit the germination of seeds, spores and other plant reproductive material, are abundant in kingdom include phenols, cyanides, alkaloids, essential oils, amino acids, etc. These inhibitors can be classified as destructors retarders depending on whether they harm morphology, structure physiology seed. closely related to seed dormancy, exogenous used extend “dorm...

Paeonia lactiflora is one of the most famous species of herbaceous peonies with gorgeous flowers. Bud dormancy is a crucial developmental process that allows P. lactiflora to survive unfavorable environmental conditions. However, little information is available on the molecular mechanism of the bud dormancy in P. lactiflora. We performed de novo transcriptome sequencing using the Illumina RNA s...

galbanum (ferula gummosa bioss) is a medicinal, commercial and industrial plant in iran but its cultivation is restricted by seed dormancy. therefore, a study was conducted to determine class and environmental requirements for breaking of seed dormancy. during imbibition study, both scarified and intact seeds exhibited similar pattern in water uptake and it seems there is not physical dormancy....

Germination ability is regulated by a combination of environmental and endogenous signals with both synergistic and antagonistic effects. Nitric oxide (NO) is a potent dormancy-releasing agent in many species, including Arabidopsis, and has been suggested to behave as an endogenous regulator of this physiological blockage. Distinct reports have also highlighted a positive impact of NO on seed g...
