Seed Priming and Smoke Water Effects on Germination and Seed Vigor of Selected Low-Vigor Forage Legumes
A commercial solid matric priming method and an osmotic priming method were used to measure seed priming responses of birdsfoot trefoil, kura clover, and sericea lespedeza. Differences were not observed using standard germination tests, but both priming methods show potential for increased …

Grain Sorghum Field Emergence and Seed Vigor Tests
… among field emergence data and laboratory seed vigor tests. Thirty-two and 30 hybrids of sorghum were planted at three Virginia locations in 1995 and 1996, respectively. Field emergence was subsequently compared with results from laboratory tests that included: 1) standard germination; 2) …

Engineering apomixis in plants to stabilize intergenerational hybrid vigor
… in crops it could be used to stabilize hybrid vigor throughout multiple generations without requiring continual hybrid crosses for seed production. Moreover, apomixis could unlock hybrid seed production in many species and lines where it is not yet possible. Here, I will discuss apomictic …

Cell cycle parameters and sweet corn emergence and seedling vigor
… with reduced emergence and poor seedling vigor. Shrunken2 genotypes with known differences for field emergence and vigor were used to investigate the contribution of seedling cell division to emergence and seedling growth. Variation among genotypes was observed for all of the cell division …

GERMINACIÓN, VIGOR, VIABILIDAD, CALIDAD Y MEJORA DE SEMILLAS DE CEBOLLA (ALLIUM CEPA L.)
In this work, it has been attempted to improve the value of a non-commercial seed lot of an onion (Allium cepa L.) local variety from Galicia, Spain. Different seed conditioning treatments have been done: prehydration, osmotic and matrix priming, hormonal and disinfection treatments. A densimetric …

The Vigor of Creative Materialism: Making the Hidden Stories of Underrepresented Engineering Students Visible
<p>Despite decades of initiatives, engineering education continues to lack diversity. The proportion of women, BIPOC, LGBTQA+, low-income, first-generation, and disabled students in engineering education remains below national population levels. The culture of engineering is a barrier to increasing …

Effects of prescribed fire timing on vigor of sericea lespedeza in the Kansas Flint Hills
… effects of annual, prescribed burning on vigor of the noxious weed, sericea lespedeza (Lespedeza cuneata; SL) in native tallgrass prairie over a 4-yr period. We hypothesized that annual prescribed burning conducted during the growing season would selectively pressure SL, whereas …

Media concentration of ownership and its effects on editorial page vigor of West Virginia daily newspapers
… concentration of ownership on editorial page vigor of West Virginia daily newspapers that changed from independent to non-independent ownership from 1965 to present. A content analysis over two-time periods, a one-week constructed sample while under independent ownership and a one-week …

The effects of priming on vigor and viability of broccoli (Brassica oleracea var. italica Plenck) seeds
… yield threshold as indicated by a significant invigoration of seeds with split testae. Despite the increased volume as a result of the formation of free spaces, primed broccoli seeds did not imbibe more water or have a greater turgor at full hydration. Priming did not lower the minimum water …

Eastern Deciduous Forest Phenology and Vegetative Vigor Trends From 2000 to 2013, Mammoth Cave National Park, KY
<p>Global climate change is predicted to affect environmental systems at the midlatitudes, but the scope, severity, and outcomes of these impacts are yet to be fully understood. This study focuses on the implications of short-term climate variability for forests in central Kentucky. Using a …

The contribution of repeat associated small RNAs to genetic variation, hybrid vigor and inbreeding depression in maize
… insight into mechanisms contributing to hybrid vigor in plants. We used Illumina sequencing to assess how sRNA populations vary between two maize inbred lines (B73, Mo17) and their vigorous hybrid (B73 x Mo17). We sampled sRNAs from the seedling shoot apex and the developing ear, two rapidly …

Effects of priming and stage of development on vigor and longevity of muskmelon (Cucumis melo L.) seeds
… determine the optimal treatment for maximal seed vigor and to test the effects of priming on seed storage life. The most effective priming treatments for improved germination of muskmelon seeds occurred at water potentials (Ψ) between -1.5 and -1.8 MPa and at priming durations of 4 to 7 days. …

Estratégia de indução de déficit hídrico em soja e desenvolvimento de GWAS para germinação e vigor de sementes
… foram realizadas análises de germinação e vigor de sementes em 97 genótipos de soja, genotipados com marcadores moleculares SNPs. A partir desses resultados se confirmou que as características relacionadas à germinação e vigor de sementes são governados vários por locus em diferentes …

Effects of maturity and seed size on seed vigor and plant growth in snap bean (Phaseolus vulgaris L.)
… harvest and relative seed size can affect seed vigor. Greenhouse and field studies were conducted to determine the effect of seed maturity on seed vigor, storability, and subsequent plant growth of four cultivars of snap bean (Topcrop, Provider Black, Provider White, and Cherokee Wax). Seeds …
