CURITIBA, Brazil, February 11, 2011 /PRNewswire/ -- Limagrain has just signed a strategic alliance in corn, through its subsidiary Vilmorin & Cie[1], with the Brazilian seeds company Sementes Guerra in Curitiba in Brazil. This entry on the Brazilian corn seed market is part of the Group's international development strategy. This agreement will extend the genetic heritage of the two parties to create more efficient varieties for the benefit of farmers. Sementes Guerra, based in...

Mechanism of spring-loaded seed launch discovered Even by invading plants' standards, the filaree, or common stork's bill, has been remarkably successful. Introduced into North America in the eighteenth century, it is now endemic in south-western states such as California, and the plant's intriguing seed dispersal mechanism seems to lie at the root of their success. Having launched as far as possible from the mother plant, the seed drills itself into the ground by repeatedly curling and...

It's commonly known, at least among microbiologists, that microbes have an additional option to living or dying "” dormancy. Dormant microbes are less like zombies and more like hibernating bears. What isn't known, however, is how large numbers of dormant microorganisms affect the natural environments when they act as microbial seed banks. In the current issue of Nature Reviews: Microbiology, Jay Lennon, Michigan State University assistant professor of microbiology and molecular...

Global warming is already affecting the earth in a variety of ways that demand our attention. Now, research carried out at the Hebrew University of Jerusalem indicates that many tree species might become extinct due to climate change if no action is taken in time. According to the research, trees which disperse their seeds by wind, such as pines and maples, will be unable to spread at a pace that can cope with expected climate changes. The research, which focused on the ecological...

Study yields new model that can help managers calculate when plants will burst bud under different climate scenariosThe opening of buds on Douglas-fir trees each spring is the result of a complex interplay between cold and warm temperatures during the winter, scientists with the U.S. Forest Service's Pacific Northwest Research Station have found.Their research"”which is featured in the December issue of Science Findings, a monthly publication of the station"”led to the development...

Mechanical properties of explosive seed dispersal in Cardamine Catapults are often associated with a medieval means of destruction, but for some plants, they are an effective way to launch new life. Dispersing seeds greater distances by catapulting can provide selective advantages, including the establishment of populations in new environments and escape from certain threats. In new work published in the recent October issue of American Journal of Botany, Dr. Ellerby, students, and...

High in an alpine meadow, Gesine Pufal, from the University of Wellington, New Zealand, crouched low to the ground and splashed some water from her water bottle on a low green plant cushion, then sat back waiting to see if something would move. Sound crazy? Many hikers passing by her may have thought so, but Pufal was trying to find potential plant species that possess a type of plant movement called hygrochasy. Although the ability to move is typically thought to be a characteristic unique...

HARRISBURG, Pa., Sept. 10 /PRNewswire-USNewswire/ -- Backyard gardeners, full-time farmers and landscaping professionals can be assured the seeds used for planting in Pennsylvania are of the highest quality due to the state's rigorous standards, said Agriculture Secretary Russell C. Redding today as his department released the 2009-10 Pennsylvania Seed Report. "As we enter the fall planting season for some vegetables, cover crops, and winter annual crops like rye, wheat and barley, it is...

A major study of agriculture in Haiti after this year's earthquake has found that much of the emergency seed aid provided after the disaster was not targeted to emergency needs. The report concludes that seed aid, when poorly-designed, could actually harm farmers or depress local markets, therefore hampering recovery from emergencies. Indeed, agricultural interventions in Haiti should move away from their emergency focus, and confront farmers' longer-term challenges, especially their poor...

Genetic analysis of Guam's cycads shows promising genetic diversity Cycads, "living fossil" descendents of the first plants that colonized land and reproduced with seeds, are rapidly going extinct because of invasive pests and habitat loss, especially those species endemic to islands. But new research on Cycas micronesica published recently as the cover article in Molecular Ecology calls into question the characterization of these plants as relicts (leftovers of formerly abundant organisms),...

Recalcitrant seeds
2013-08-21 08:52:36

Recalcitrant seeds are seeds that have to be protected from certain elements, such as drying and freezing, to remain viable. Seeds must be maintained at temperatures no less than 50 degrees Fahrenheit and does not have long shelf lives. Damage to the seeds results when they are allowed to dry out excessively, damaging the intracellular structures of the seeds, along with the forming of toxic chemicals within the seed. Recalcitrant seeds can be found in avocado, mango, cocoa and the...

Seed bank
2013-07-31 15:37:35

Seed banks are gene pools of seeds from food crops and other rare species. If seeds from the reserves are destroyed, seeds from seed banks can be used to generate new crops. Seed banks are not open to the public as are seed libraries or seed swaps. Maintaining seeds in a seed bank will preserve the seeds during times of natural disasters, disease outbreaks, or even war. SEED DORMANCY Seeds can remain dormant for decades as long as the storage environment remains cool and dry. Seeds that...

Seed Drilling
2013-05-18 07:39:11

Seed drilling is a method used by farmers in order to have a more unified, crop-yielding season. The first known use of seed drilling was in 1500 BC by the Sumerian. At this time, they were using a single tube. Later, in the 2nd Century BC, the Chinese developed a multi-tube iron drill. This facilitated in a larger crop planting allowing them to feed their large population. The first recorded patent of a sowing machine was in 1566 by the Venetian Senate, attributing Camillo Torello. In the...

Seed Saving
2013-05-18 07:22:11

Seed saving is the preserving of seeds from mature vegetables, herbs, and flowers used in subsequent years along with bulbs and tubers. Home gardeners have saved seeds for generations and the practice is now becoming common with organic farmers as well as permaculturists. Growers will clone plants so as not to produce seeds keeping the plant “true to type” to the parent plant. True to type refers to the characteristics of the parent plant such as large fruit/blooms. Plants...

Biennial Plant
2013-04-27 07:50:37

Biennial plants have a two year life cycle; roots, stems and leaves in the first year with flowers following the next year after a cold winter dormant period. Biennials will produce seed and fruit before dying. There are not as many biennial plants as there are perennials or annuals. Biennial plants, when exposed to extreme climate conditions, may have a shortened life cycle of a few months especially if the plants were exposed to colder than normal temperatures. Most biennials can be...
