Lipid Thermal Fingerprints of Long-term Stored Seeds of Brassicaceae
Thermal fingerprints for seeds of 20 crop wild relatives of Brassicaceae stored for 8 to 44 years at the Plant Germplasm Bank—Universidad Politécnica de Madrid and the Royal Botanic Gardens, Kew’s Millennium Seed Bank—were generated using differential scanning calorimetry (DSC) and analyzed in relation to storage stability. Relatively poor storing... -

Comparative Seed Morphology of Tropical and Temperate Orchid Species with Different Growth Habits
Seed morphology underpins many critical biological and ecological processes, such as seed dormancy and germination, dispersal, and persistence. It is also a valuable taxonomic trait that can provide information about plant evolution and adaptations to different ecological niches. This study characterised and compared various seed morphological traits, i.e., seed and...Diantina, Surya ; McGill, Craig ; Millner, James ; Nadarajan, Jayanthi ; Pritchard, Hugh W. …

The negative effect of a vertically-transmitted fungal endophyte on seed longevity is stronger than that of ozone transgenerational effect

It is also a valuable taxonomic trait that can provide information about plant evolution and adaptations to different ecological niches.

Comparative in vitro seed germination and seedling development in tropical and temperate epiphytic and temperate terrestrial orchids
Ex situ conservation of orchid seeds requires the application of modern biotechnology to determine seed quality and to optimise in vitro regeneration. The nutrient requirements for germination and seedling growth in vitro can be species-specific and influenced by life history traits and habitats. Therefore, this study aimed to explore in... -

Seed Longevity—The Evolution of Knowledge and a Conceptual Framework.
The lifespan or longevity of a seed is the time period over which it can remain viable. Seed longevity is a complex trait and varies greatly between species and even seed lots of the same species. Our scientific understanding of seed longevity has advanced from anecdotal ‘Thumb Rules,’ to empirically...Nadarajan, Jayanthi ; Walters, Christina ; Pritchard, Hugh W. ; Ballesteros, Daniel ; Colville, Louise

Comparative Seed Cryopreservation of Indonesian and New Zealand Epiphytic And Terrestrial Orchids.
The atypical seed storage behaviour reported in several orchid species justifies cryopreservation as a complementary conservation strategy to conventional seed banking. This study aimed to assess the seed cryopreservation potential of five orchid species; tropical epiphytic, Indonesian species (Dendrobium strebloceras, D. lineale), one temperate New Zealand species (D. cunninghamii) and...
