Experiment on estimation of qualitative changes in populations of meadow fescue (Festuca pratensis Huds.) after seed storage in different conditions were taken. Phenotypical traits for plants derived from seeds stored during 54 months in two different kind of storage conditions were compared. Storage of meadow fescue seed during 54 months in unfavourable conditions resulted in decrease of initi...

in order to evaluate the genetic diversity of common bean (phaseolus vulgaris l.) and the relationships between studied characteristics with seed storage proteins, 60 genotypes with three colors (white, red and pinto bean) were studied using an augmented design with three blocks and four varieties as controls. the majority of studied traits were significantly different between large and small s...

Proteomics approaches have been a useful tool for determining the biological roles and functions of individual proteins and identifying the molecular mechanisms that govern seed germination, vigour and viability in response to ageing. In this work the dry seed proteome of four Arabidopsis thaliana genotypes, that carry introgression fragments at the position of seed longevity quantitative trait...

Seed banking is now widely used for the ex situ conservation of wild plant species. Many seed banks that conserve wild species broadly follow international genebank guidelines for seed collection, processing, storage, and management. However, over the last 10-20 years, problems and knowledge gaps have been identified, which have led to more focused seed conservation research on diverse species....

Breeding soybean for high seed quality is an important approach for developing cultivars for tropical regions, and the lignin content in the seed coat is one of the screening parameters for this trait. Considering that many breeding lines are evaluated in each growing season using the presently recommended method for lignin determination, a long period is required for the evaluation of the whol...

A comparative study of proteome and transcriptome changes during Medicago truncatula (cultivar Jemalong) seed development has been carried out. Transcript and protein profiles were parallel across the time course for 50% of the comparisons made, but divergent patterns were also observed, indicative of post-transcriptional events. These data, combined with the analysis of transcript and protein ...

during the fragmented phases of the tree-improvement delivery system are reviewed. The impacts of intentional and unintentional directional selection during phenotypic selection, seed production (with its associated reproductive-phenology asynchrony, fecundity differential and varying propensity to inbreeding), seed processing and storage, and seedling production are evaluated. In general, gene...

Seed priming is a commercially successful practice, but reduced longevity of primed seeds during storage may limit its application. We established a series of experiments on rice to test: (1) whether prolonged storage of primed and non-primed rice seeds for 210 days at 25°C or -4°C would alter their viability, (2) how long primed rice seed would potentially remain viable at 25°C storage, and (3...
