Canadian researchers say they've determined the scent of grapevine flowers comes from pollen grains stored in the anthers, not just the petals. University of British Columbia scientists from the school's Wine Research Center and Michael Smith Laboratories were studying grapes used to produce Cabernet Sauvignon from British Columbia's Okanagan region when they identified a gene that produces and regulates fragrance from the vines' tiny clusters of green blossoms. This was a surprise in...

U.S. scientists say they've determined the seeds of some tree species can survive for more than 30 years before germinating -- 10 times longer than thought. Lawrence Livermore National Laboratory scientist Tom Brown and University of Illinois Professor James Dalling said they measured the amount of carbon 14 in seeds of Panamanian rain forest trees Croton billbergianus (Euphorbiaceae), Trema micrantha (Celtidaceae) and Zanthoxylum ekmannii ( Rutaceae). They discovered the seeds survived in...

Purdue University researchers have determined a process that regulates activity of genes that control seed germination and seedling development. Mike Hasegawa, the Bruno C. Moser Distinguished Professor of Horticulture and Landscape Architecture, and Kenji Miura, a former Purdue postdoctoral researcher and now an assistant professor at Tsukuba University in Japan, discovered the step involved in keeping seeds from germinating in adverse conditions such as freezing temperatures or drought, a...

Florverde(R)-Certified Flower Farms Plan to Ship More Than 300 Million Flowers to the U.S. For the Holiday of Love BOGOTA, Colombia, Jan. 29 /PRNewswire-USNewswire/ -- Although consumer spending may be down, there's one area where many Americans are willing to forego the budget and that's romance. In fact, according to the just-released National Retail Federation's 2009 Valentine's Day Consumer Intentions and Actions survey, conducted by BIGresearch, this year the number of flower purchases...

Only 2 genes make the difference between herbaceous plants and trees Annuals and perennials Annual crops grow, blossom and die within one year. Perennials overwinter and grow again the following year. The life strategy of many annuals consists of rapid growth following germination and rapid transition to flower and seed formation, thus preventing the loss of energy needed to create permanent structures. They germinate quickly after the winter so that they come out before other plants, thus...

MU researcher identifies pollen proteins that provide insight into the fertilization process Without eyes or ears, plants must rely on the interaction of molecules to determine appropriate mating partners and avoid inbreeding. In a new study, University of Missouri researchers have identified pollen proteins that may contribute to the signaling processes that determine if a plant accepts or rejects individual pollen grains for reproduction. Like humans, the mating game isn't always easy for...

A team of scientists at the Hebrew University of Jerusalem has found a way to genetically enhance the scent of flowers and implant a scent in those that don't have one. Smell plays an important role in our lives: It influences the way in which we choose fruit and vegetables, perfume, and even a partner. And yet, smell is not just what we smell with our noses, it's also what we taste, explains Prof. Alexander Vainstein, who is heading the team at the Robert H. Smith Faculty of Agriculture,...

THERE'S nothing like the smell of rotting flesh in the morning, especially if you are a botanist. Monday morning, volunteers and botanists at UC Berkeley Botanical Gardens arrived to see the fruits of their labor reach fruition as "Odora," the corpse flower, emitted a smell that only a carrion beetle would find appealing. "It pushes the odor a mile," volunteer Judith Finn said. After 13 years, Odora finally grew into the "flowering structure" every botanist could wish for. Most...

By Renaldo Smith, The Miami Herald Jun. 15--Breyana Roundtree was a bundle of energy. After glancing over a poster collage of pictures of rain forests, she rushed over to a table about 10 feet away and started to paint. Minutes later, she was in the corner putting seeds in a cup as part of a seed germination exercise. As much as her activities changed, though, the smile on the face of the 7-year-old remained the same. Breyana was among children and adults who turned out for the...
