Seed ageing, survival, and the improved seed viability equation; forty years on [PDF]

, 2022
Seed Science and Technology published ‘The quantification of ageing and survival in orthodox seeds’ four decades ago. That paper explained the improved seed viability equation, which quantifies seed longevity in response to storage environment, and the ...

Quality of peanut mechanical sowing in function of seeding density and size of the seeds [PDF]

Engenharia Agrícola, 2015
ABSTRACT Peanut crop (Arachis hypogaea L.) mechanization has been improved over the years; however there are drawbacks that affect the quality of operations. Thus, this article’s objectives were to evaluate the operational performance of the mechanized sowing of peanut crop according to seeding densities (10, 14, and 18 seeds m-1) and seed sizes (21 ...

Spatial and temporal patterns of carabid activity-density in cereals do not explain levels of predation on weed seeds [PDF]

, 2008
Seed predation is an important component of seed mortality of weeds in agro-ecosystems, but the agronomic use and management of this natural weed suppression is hampered by a lack of insight in the underlying ecological processes.

Genome-Wide Association Analysis Identifies Candidate Genes Regulating Seed Number per Silique in Arabidopsis thaliana

Plants, 2020
Seed weight and number ultimately determine seed yield. Arabidopsis seed number comprised of silique number and seed number per silique (SNS). Comparing seed development and weight, determinants of seed number remain largely uncharacterized.
