The Persimmon Creek meteorite

Persimmon growing in NSW

China is the world’s biggest producer, followed by Japan and Korea while Italy is the main European producer (70 000 tonnes in 1993). The Australian persimmon industry has a farm-gate value of between $9 million and $10 million, with 280 producers (2000). Annual production is 2100 tonnes from approximately 300 000 trees. Most plantings (65%) consist of young trees less than six years old; more ...

The Power of Plasticity in Polyploid Persimmon.

Most plants are hermaphrodites, producing perfect flowers with both male and female functions. In roughly 6%of plants, however, male (usually XY) plants produce only male flowers and female (XX) plants produce only female flowers. Thesedioecious plants cannot self-pollinate, ensuring genetic diversity and facilitating the breeding process. In the dioecious diploid persimmon (Diospyros lotus), s...

The Broken Belt: Meteorite Concentrations

Introduction: Since the first Antarctic meteorite concentrations were discovered more than 25 years ago, many theories regarding the role of iceflow in the production of meteorite concentrations have been put forward , and most agree on the basic principles [1-3]. These models suggest that as the East Antarctic icesheet flows toward the margins of the continent, meteorites randomly located with...

Meteorite studies

eteorites yield a wealth of information concerning Solar System origin, geochemical evolution of primitive parent objects, and irradiation histories of material in space. Since the numerous (approximately 16,000) antarctic meteorites include many of rare or unique types, current extraterrestrial materials research attention focuses on this population. Antarctic meteorites also have the potentia...
