Alfalfa (Medicago sativa L.) is one of the most widely cultivated perennial forage legumes worldwide. Fall dormancy is an adaptive character related to the biomass production and winter survival in alfalfa. The physiological, biochemical and molecular mechanisms causing fall dormancy and the related genes have not been well studied. In this study, we sequenced two standard varieties of alfalfa ...

henbane hyoscyamus reticulatus l. is a plant species in solanaceae family that seeds hardly germinate because of seed dormancy. in order to determine the best methods for seed dormancy breaking in henbane, a experiment was conducted as a completely randomized design with three replications. the treatments included moist pre-chilling (at 4 °c) for 7, 14, 21 and 28 days, combined treatment of gib...

Abstract Information in the literature and unpublished results of authors on Dobinea were used to determine kind [class(es)] seed (true + endocarp) dormancy non-dormancy genera all five tribes Anacardiaceae, examined relation taxonomic position endocarp anatomy within family. Reports both germination found for 15 tribe Spondiadeae, 6 Anacardieae, 30 Rhoeae, 3 Semecarpeae 1 Dobineeae. In Spondia...

Wild barley (Hordeum vulgare ssp. spontaneum) has strong grain dormancy, a trait that may enhance its survival in non-cultivated environments; by contrast, cultivated barley (Hordeum vulgare ssp. vulgare) has weaker dormancy, allowing uniform germination in cultivation. Malting barley cultivars have been bred for especially weak dormancy to optimize their use in malt production. Here, we analyz...

Abstract The study was conducted to determine the dormancy and physiological age characteristics of diverse potato genotypes as influenced by growing altitudes seasons for future breeding strategies optimal patterns use. Dormancy sprouting have an impact on tuber production, storability seed quality planting ware consumption market. This presents results measurements 47 grown at three with repl...

Eastern black walnut (Juglans nigra L.) is used as a rootstock for the Persian walnut (Juglans regia L.) in some parts of the world and also has an important role in forestry and wood industry. Due to the deep physiological dormancy, the seed often shows an inconsistent or low germination percentage, making establishment difficult. This experiment was carried out as a completely randomized desi...

Abstract: Seed conditioning improves germination uniformity, speed, and dormancy release. This work aimed the study physiological of Urochloa humidicola cv. Llanero, using two lots dormant seeds conditioned by imbibition with water, commercial bioregulator (auxin, gibberellin - 0.144 mM cytokinin), (0.144 1.44 mM) or 5% ethanol. Germination, dormancy, SOD activity, MDA H2O2 content were evaluat...

Studying seed dormancy and its consequent effect can provide important information for vegetation restoration and management. The present study investigated seed dormancy, seedling emergence and seed survival in the soil seed bank of Stipa bungeana, a grass species used in restoration of degraded land on the Loess Plateau in northwest China. Dormancy of fresh seeds was determined by incubation ...

The life stages of seed germination and seedling establishment play a vital role in maintaining plant populations and determining range dynamics of species. Thus, it is not surprising that specific germination requirements and dormancy mechanisms have evolved in all major angiosperm clades. In a rapidly changing climate, we face growing pressure to manage, conserve and restore native plant spec...
