Christmas Tree Research Grant Aims to Solve Major Problems for Industry

New research will address Christmas tree issues--and possibly expand the market for live trees.
New research will address Christmas tree issues–and possibly expand the market for live trees.

One of the biggest problems for Christmas tree growers is Phytophthora root rot, a fungus disease that can shrink plantation yields up to 75 percent. A related issue (though a little less consequential) for consumers of live Christmas trees is the mess in their homes from fallen needles. Researchers at Washington State University and other universities hope to battle both of these problems with the support of a five-year, $1.3 million grant from the USDA National Institute of Food and Agriculture.

“The Christmas tree industry has some big challenges,” said WSU Christmas tree researcher Gary Chastagner, “and we hope that this national project will bring together scientific expertise and techniques to address these two issues.” Focusing on true firs, the researchers will leverage the genomics groups at North Carolina State University and the University of California, Davis, to find genetic markers for Phytophthora resistance and needle retention.

“Phytophthora root rot plagues all regions where firs are grown as Christmas trees,” said John Frampton, Christmas tree geneticist at NCSU and a collaborator on the project. There is no effective control for Phytophthora, so the best way to tackle the problem is to find resistant tree species. Chastagner’s graduate student, Katie McKeever, is collecting isolates of Phytophthora in various growing areas. By sequencing these samples and conducting pathogenicity trials, McKeever will contribute critical information to the team’s search for mechanisms of resistance in trees. Once the researchers find the relevant genetic markers, they can screen adult trees and select the most promising as seed sources for viable Christmas tree plantations.

The team will use similar techniques to resolve the matter of needle shedding. Chastagner’s multi-decade cataloging of Christmas trees with varying degrees of postharvest needle retention will give this part of the project a jump-start. By using these and other trees, scientists will be able to quickly identify needle-retentive gene sources so that growers can produce desirable Christmas trees.

Translating the Research to the Market

But even if growers have trees that don’t suffer root rot or needle loss, how can they be sure that consumers will flock to buy their new and improved products? After all, the number of live Christmas trees sold in the United States has remained relatively static for decades. Any increase in the Christmas tree market is absorbed by the number of artificial trees sold each year.

To address the stalled market growth for live Christmas trees, Jeff Joireman, WSU associate professor of marketing, will research specific consumer preferences with a nationally-representative survey followed by focus groups. Rick Dungey of the National Christmas Tree Association expects the data to expand the types of trees offered at commercial lots and U-cut farms across the country.

“Some people want an old-fashioned tree like grandma had,” Dungey said, referring to a live tree with a more open structure, in contrast to the closely-sheared, densely branched trees crafted by today’s Christmas tree industry. Dungey also noted the availability of live tree rentals in some areas, as well as narrow “condo” or “loft” trees in New York City, favored by those with insufficient space for the traditionally broad Christmas tree. “Consumers want more types and styles of trees,” Dungey said. “The marketing part of this project will examine the Christmas tree industry from the end user’s perspective, and allow the industry to respond to those desires.”

A new study by researchers at Washington State University shows that mechanical harvesting of cider apples can provide labor and cost savings without affecting fruit, juice, or cider quality.
The study, published in the journal HortTechnology in October, is one of several studies focused on cider apple production in Washington State. It was conducted in response to growing demand for hard cider apples in the state and the nation…MORE

SubsurfaceIrrigationWSU wins national award for water-saving research

By Sylvia Kantor, College of Agricultural, Human & Natural Resource Sciences

Water scarcity – one of the toughest challenges predicted for the 21st century – is being addressed by Washington State University. As part of a multistate research program, WSU is among 19 land-grant universities honored recently for their efforts to help farmers irrigate their land more efficiently, especially during droughts and water shortages.
“A safe, reliable supply of water is inextricably linked to food security,” said Sonny Ramaswamy, director of the USDA National Institute of Food and Agriculture…MORE

Apples-USDA-ARS-350An apple a day could keep obesity away

By Sylvia Kantor, College of Agricultural, Human & Natural Resource Sciences

PULLMAN, Wash. – Scientists at Washington State University have concluded that nondigestible compounds in apples – specifically, Granny Smith apples – may help prevent disorders associated with obesity. The study, thought to be the first to assess these compounds in apple cultivars grown in the Pacific Northwest, appears in October’s print edition of the journal Food Chemistry. “We know that, in general, apples are a good source of these nondigestible compounds but there are differences in varieties,” said food scientist Giuliana Noratto, the study’s lead researcher. “Results from this study will help consumers to discriminate between apple varieties that can aid in the fight against obesity.” MORE

PULLMAN, Wash. – Drug abuse, acts of rampage – what’s really the matter with kids today? While there are many places to lay blame – family, attitude, peers, school, community – a new study shows that those risks vary in intensity from kid to kid and can be identified.

Scientists at Washington State University and Pennsylvania State University have found a way to spot the adolescents most susceptible to specific risk factors for delinquency MORE

MudflatImpact: Burrowing Shrimp and Invasive Eelgrass

Shellfish production in Washington is a $60 million a year industry. Several major pests plague this industry, resulting in major crop loss. One of the most important pests is subterranean burrowing shrimp. These shrimp bioturbate (stir up) the sediment, causing the oysters to sink and die. For the past 60 years the industry has been using the insecticide Sevin to control this pest, but due to lawsuits its use was phased out in 2012. Without alternative control for shrimp, tens of millions of dollars in annual crop revenue will be lost and the industry will quickly lose its economic viability in southwestern Washington.

PoultryFarmImpact: The National Livestock and Poultry Environmental Learning Center

The Environmental Protection Agency has identified agriculture as the leading contributor of pollutants to the nation’s rivers, streams, lakes, and reservoirs. These reports often do not separate animal agriculture from other agricultural enterprises, but they do note that pathogens, nutrients, and oxygen-depleting substances associated with manure are three of the top five pollutants. Some emerging issues related to manure management include: endocrine disruptors (hormones), pharmaceuticals (antimicrobials), and antibiotic resistance in bacteria. Adopting farm practices that minimize the environmental impact is important for food safety.

BiosolidsImpact: Biosolids and Compost

Biosolids are the solids produced during municipal wastewater treatment. Composts are made from a variety of organic materials, including both urban and agriculture sources such as yard trimmings, biosolids, storm debris, food waste or manure, and food processing residues. While these materials have traditionally been viewed as waste, they can play a valuable role as soil amendments in urban and agricultural settings. They provide nutrients and organic matter and they sequester carbon, thereby conserving resources, restoring soils, and combating climate change.
