A new study found that seeds from different orchid species could stay alive and ready to grow for over 10 years even when stored in a deep freezer, showing that saving orchid seeds for the long term in seed banks is...

Dormancy and endosperm presence influence the seed longevity of central European calcareous grassland plants
Despite increasing efforts towards habitat and species protection in Europe since the 1990s, when the Fauna-Flora-Habitat directive was adopted, the proportion of threatened plant species has steadily increased. One...

High-temperature drying increases longevity of rice seed
This study investigates the conditions routinely used by genebanks and finds that standard practice may not be optimal for subsequent seed longevity.

Transgenerational changes in seed longevity in Silene
A study of seeds from alpine & lowland populations of Silene vulgaris shows that seed longevity has a genetic basis, but may show strong adaptive responses.
Seed ageing at elevated oxygen pressure
Subjecting seeds to elevated oxygen concentrations may provide a novel method for studying ageing processes. Groot et al. test this hypothesis by storing dry seed of barley (Hordeum vulgare), cabbage (Brassica...
Seed of alpine plants are short-lived in storage
Seed of alpine plants are short-lived in storage Alpine ecosystems are considered as being particularly vulnerable to the effects of climate change. Mondoni et al. report that seeds of alpine plants are short-lived in...
