Michigan Tech Winter takes its toll on living things. To protect themselves from the elements, bears hibernate, and trees go dormant.   Biologists have observed what happens when trees become dormant, but up to now, they haven’t understood the underlying genetic mechanisms that enable them to start growing again. A team led by molecular geneticists from Michigan Technological University has identified and characterized a gene that tells a poplar tree when winter ends and a spring...

Technique reduces cluster compactness, harvest season rot Wine grape production in the Great Lakes Viticultural Region can be a challenging enterprise. Spring frost, winter injury, short and variable growing seasons, and cool, humid growing conditions subject grape vines to disease, including harvest season cluster rot. Tight-clustered wine grape varieties in the region show varying susceptibility to cluster rot; cultivars such as Pinot gris, Pinot noir, Riesling, Seyval, and Vignoles are...

NEW YORK, Nov. 30, 2010 /PRNewswire/ -- The Vinho Verde Regional Viticultural Commission (CVRVV) is happy to announce that the harvest period, which ended in late October, has resulted in a 2010 vintage characterized by balance and quality. After a cold and wet winter in the Vinho Verde region, bud-break was slightly later than usual, and the water in the soil led to increased vigor and a good rate of bud-break. Variable weather conditions followed bud break, but higher temperatures in the...

Stanford researchers on how irrigation water slips away and how to stanch the flow Getting the most out of every drop of water is a high priority for grape growers in the southern Napa Valley, where summers are hot and dry and vines have to be irrigated to make it through the growing season. But Stanford researchers have found that a significant portion of the water applied to the vines zips right by the plants, hardly even pausing. "We found that about 10 percent of the water that is applied...

By Buzz Bertolero Q: My husband has read that fruit trees could be pruned once they stop producing. Is this true, or do we have to wait until all the leaves fall off to prune our plum, peach and nectarine trees? A: The short answer is you don't have to wait for the leaves to drop to prune deciduous fruit trees, but this long-established norm is changing. The winter months are still an excellent time to prune and shape, as the structure of the tree is easier to see without all the...


Word of the Day
humgruffin
  • A terrible or repulsive person.
