Hurricane damage creates pecan shortage

28.10.2004


Rich pecan pie is a long-time favorite dessert of the holiday season. But this year, the amount of pecans harvested will be dramatically down due to substantial damage from the 2004 hurricanes, say plant health specialists with The American Phytopathological Society (APS).



Pecan growers in Georgia and Alabama, two of the primary pecan growing areas were already expecting a light production year due to reduced nut set on many cultivars, said Tim Brenneman, APS member and plant pathologist with the University of Georgia. "But then the hurricanes came late in the growing season and caused tremendous damage to pecan crops in these two states," he said.

Georgia, which normally produces 120 million pounds of pecans annually, lost an estimated 50 percent of its already reduced pecan crop. Alabama, which took a direct hit from Hurricane Ivan, lost 80 percent of its total crop. Damage to the pecan trees include pecans blown prematurely from the limbs, twisted limbs and limb breakage, as well as severe tree leaning and loss of entire trees. Approximately 15-20 percent of all pecan trees in the state of Alabama were destroyed. "We aren’t yet certain of the full effect the damage has had on the remaining trees," said Brenneman. "There’s evidence that some trees may not fully recover," he said. Many farmers have tried to save the injured trees by using tractors to pull the trees straight and remove damaged limbs.


Pecan trees take many years to get into full production. The stress on damaged trees may affect pecan production for years to come. "Next year’s crop is dependent on the health of the trees when they go into winter," said Brenneman.

Another problem brought on by the hurricanes is increased pecan disease. One disease that normally doesn’t appear, Phytophthora shuck and kernel rot, has appeared in the middle of the Georgia pecan growing area. The disease, caused by a fungus-like organism, occurs when there is an extended period of cool, wet weather much like the weather caused by the hurricanes. The disease causes the kernel to discolor and rot, rendering it inedible. "The appearance of this disease has really compounded the situation," said Brenneman. Plant health specialists are working with growers to control the outbreak of this disease.

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
