GAINESVILLE, Fla. — University of Florida researchers have some encouraging results in the battle against citrus greening.

They have identified citrus cultivars, in this case 16 citrus rootstocks, most of which show a lower rate of infection and more tolerance to citrus greening – the dreaded disease that has wreaked havoc through Florida’s citrus industry since its arrival in the state in 2005.

GAINESVILLE, Fla. — With the time for Florida growers to plant strawberries right around the corner, it won’t be long before Florida-grown strawberries appear in grocery aisles.

And for some of the best-tasting strawberries on the market according to multiple taste panels and tests, shoppers can simply look for those grown in the Sunshine State, thanks to work by the University of Florida.

Researchers with UF’s Institute of Food and Agricultural Sciences have continued to improve the quality and flavor of Florida-grown strawberries, as evident in their latest releases of the cultivars Winterstar and Florida Sensation.

GAINESVILLE, Fla. — Animal biodiversity suffers near conservation areas that border big farms, and the effects can spread for miles, according to a new study by University of Florida researchers and their colleagues.

Maintaining animal biodiversity is important as it can lead to greater control of agricultural pests and increased pollination around farmland as well as help maintain the health of an area’s ecosystem, said Robert McCleery, a study co-author.

The researchers studied small mammal populations across large-scale sugarcane production areas and adjacent to isolated pockets of conservation land in Swaziland, Africa. The study was published Monday in the online journal PLOS ONE and can be viewed here: http://dx.plos.org/10.1371/journal.pone.0074520.

GAINESVILLE, Fla. – Two papers co-authored by a University of Florida professor have been highlighted by a leading science journal.

The science journal Plant Physiology recently named the studies “Crop Genome Plasticity and Its Relevance to Food and Feed Safety of Genetically Engineered Breeding Stacks” and “Evaluating the Potential for Adverse Interactions within Genetically Engineered Breeding Stacks” as Editor’s Choice papers.

The papers were co-authored by Curtis Hannah, an professor with the horticultural sciences department, part of the UF Institute of Food and Agricultural Sciences.

GAINESVILLE, Fla. — Florida’s agriculture, natural resources and related food industries provided a $104 billion impact on the state in 2011 and have continued to improve since the 2008 recession, according to a new University of Florida study.

The study is the latest report from researchers in UF’s food and resource economics department — part of the Institute of Food and Agricultural Sciences — on the industries’ economic contributions. It can be viewed here: http://edis.ifas.ufl.edu/pdffiles/FE/FE93500.pdf.

The industries include crop, livestock, forestry and fisheries production; agricultural product and service providers; food product manufacturing; forest product manufacturing; food distribution; mining and nature-based recreation.

GAINESVILLE, Fla. — University of Florida researchers have found, for the first time, that crop models predicting yields for one of the world’s most important crops begin to disagree under climate change scenarios.

By knowing where those models break down, researchers will be better able to improve them. The computerized models predict crop yields for wheat, one of the world’s most-consumed foods.

Scientists use crop models to foresee which parts of the world may face the greatest food shortages, so that efforts to improve food production can be directed to those places.

Auxins could help crops beat heat and high salinity, UF study suggests

GAINESVILLE, Fla. — The plant hormones called auxins are well-known for stimulating development of roots and other structures, and now University of Florida scientists have shown that auxins help plants cope with environmental stresses.

The findings could lead to crop varieties that better tolerate heat and salinity, said author Bala Rathinasabapathi, a professor with UF’s Institute of Food and Agricultural Sciences.

“Our findings show there’s a possibility of manipulating plant stress tolerance with auxins,” Rathinasabapathi said. It may be possible to administer auxins to crops at critical stages of growth, he said, or possibly engineer new varieties that respond to auxins more efficiently.

GAINESVILLE, Fla. — Integrated weed management, or IWM, is a management option for crop producers who want to fight weeds using every available technology; it involves three activities – scouting, prevention and control – coordinated to discourage weeds from growing in the first place.

Producers have been slow to adopt IWM, but a team of scientists with the University of Florida’s Institute of Food and Agricultural Sciences say it can be a sustainable, affordable choice.

In fact, the team publishes so much research on the subject that they earned UF several top five results in a recent study that assessed the productivity of weed science teams worldwide.

UF breaks ground for new 7,800-square-foot Austin Cary Forest Learning Center

GAINESVILLE, Fla. — A new era began for the University of Florida’s School of Forest Resources and Conservation April 6 as ground was broken for the Austin Cary Forest Learning Center, a 7,800-square-foot education and outreach complex in the heart of the UF-owned forest northeast of Gainesville.

The learning center will succeed and surpass the Austin Cary Forest Conference Center, destroyed by fire in July 2011. Fundraising and recovery efforts began immediately after the fire, and at the groundbreaking event, UF Senior Vice President for Agriculture and Natural Resources Jack Payne expressed awe at their rapid progress.

“I never thought we’d be here two years later,” said Payne, who noted the importance of forest products to the state’s economy — $15 billion and 90,000 jobs. Speaking to a crowd of about 400 supporters, he discussed the Austin Cary Forest’s role as an essential link between natural resources and agriculture, and the role that pine trees may play in providing more of the world’s biofuel and fiber needs.

Construction for the learning center is slated to begin immediately and should be completed in less than one year, SFRC Director Tim White told attendees. The learning center will greatly enhance the school’s ability to provide distance education from Austin Cary Forest and accommodate large in-person events there, he said.

“This is a community resource, not an SFRC resource,” White said. “Tell people we want it to be used.”
