Seeds of different species are believed to have characteristic shelf lives, although data confirming this are scarce, and a mechanistic understanding of why this should be remains elusive. We have quantified storage performance of c. 42,000 seed accessions, representing 276 species, within the USDA National Plant Germplasm System (NPGS) collection, as well as a smaller experiment of 207 cultivars from 42 species. Accessions from the NPGS collection were harvested between 1934 and 1975, and had…

The longevity of crop seeds stored under ambient conditions
- BiologySeed Science Research
- 2009
A significant correlation was obtained between germination performance in the laboratory and seedling emergence following autumn sowing, and Seeds in which oil was the major seed storage component were more short lived, whereas carbohydrates or proteins did not show an effect on seed longevity.
Variation in seed longevity among diverse Indica rice varieties

This is the first study to describe the extent of variation in σ within a species’ variety group as well as identify eight major loci associated with seed longevity parameters through genome-wide association (GWA) analysis.
Variation in seed longevity among different populations, species and genera found in collections from wild Australian plants

The data show that it can be risky to expect accurate prediction of seed longevity for a wild species on the basis of survival data from a single collection, and a relationship between variation in s and the breeding system is proposed for Wahlenbergia.

The more rapid loss of seed viability detected in the active chamber suggests that the seed conservation approach, based on the storage of the same seed accessions in two chambers with different temperatures, might be counterproductive for overall long-term conservation and that base conditions should be applied in both.

It is found that the seeds preserved in the MSB did not decrease in viability, with ultrastructural features similar to those in freshly harvested seeds, which contrast with previous reports that date seeds could remain viable for ∼2000 years in uncontrolled storage environments.
Germination of 151-year old Acacia spp. seeds
- Environmental ScienceGenetic Resources and Crop Evolution
- 2009
Germination tests were performed on a collection of seeds from five Acacia species made in Egypt in 1856 suggesting that these genera are suitable for studies on the characteristics of seeds with long storage performance and demonstrating that herbaria and seed collections stored in museums and institutional depositories can be alternate sources of plants genetic material.

The data suggest that the endospermic seeds of early angiosperms which evolved in forest understorey habitats are short-lived, and may have implications for re-collection and re-testing strategies in ex situ conservation.

Survival of dry and ultra-dry seeds of carrot, groundnut, lettuce, oilseed rape, and onion during five years' hermetic storage at two temperatures
- Biology
- 1996
Investigations were carried out to determine whether or not hermetic storage at lower moisture contents would provide better seed survival, particularly in circumstances where refrigeration cannot be provided, and to confirm that storage at -20°C rather than 20°C is beneficial to seed survival.

It is suggested that in dry tissues, enzyme-controlled turnover and repair may be temporarily suspended, and that this may be an important factor in the loss of seed viability in storage.

Agricultural production of food and fiber depends on the ability of seeds to dry and become quiescent for a period before planting for the next season’s crop. In many instances seed must be kept for…
Temperature and Seed Storage Longevity

The quantitative relation between seed longevity and temperature does not vary among diverse species, and the coefficient of the viability equation did not differ significantly among the eight species despite their contrasting taxonomy.

Regression analysis of data from storage periods up to 5-5 years at temperatures of 5-75 °C and seed moisture contents of 3*6-1 3-6 per cent yielded the following values, suggesting that for low moisture contents the viability equation can be applied to estimate longevity at sub-zero temperatures.

Seed Persistence: A Correlation Between Seed Longevity in the Soil and Ortho-Dihydroxyphenol Concentration
- Biology
- 1994
It is concluded that ortho-dihydroxyphenols, as a class, play an important role in maintaining seed persistence in the soil, probably by deferring or decreasing the rate of decomposition by microbes as well as by defending against herbivory.

Activity of the protein-repair enzyme L-isoaspartyl methyltransferase in the old lotus seed is persistent during germination and is as robust as that in the progeny, and the degree of aspartyl racemization in proteins of the two groups of plants is minimal and essentially identical.
