Several new apple varieties recommended for growers

20.05.2014

Long-term study finds new strains could boost consumer acceptance of 'Fuji' apples

 'Fuji' apples have become increasingly popular among consumers, but the apple variety faces some challenges on its path to full consumer appreciation. Research has determined that "consumer acceptance" of apples depends largely on fruit color, size, eating quality, and texture.

Consumers are very discerning: poor color can drastically reduce the value of red apples, even if their size is acceptable. The poor and inconsistent peel color of 'Fuji' apple strains has limited the apple's marketability. The authors of a new study say that the introduction of new 'Fuji' strains could increase the apple's popularity and drive up consumer approval.

Esmaeil Fallahi, Bahar Fallahi, and Bahman Shafii from the University of Idaho and Zabihollah Zamani from the University of Tehran published the results of their 6-year study in HortScience. The team studied the long-term effects of five 'Fuji' strains ('Autumn Rose', 'Desert Rose', 'Myra', 'September Wonder', and 'Top Export' on RN 29 rootstock) on fruit yield and harvest time quality.

"This experiment was designed to determine differences among 'Fuji' strains in southwestern Idaho, which has similar climate conditions as those of the Intermountain West region of the United States and many other regions worldwide," explained author Esmaeil Fallahi, Director of Pomology at the University of Idaho.

The researchers found that fruit of 'September Wonder Fuji' trees were larger than those of other strains in 5 of the 6 years that the experiments took place. 'September Wonder' fruit was less firm than the other strains, but showed a higher starch degradation pattern every year, traits the researchers attributed to the strain's earlier maturity.

"Considering all yield and quality attributes at harvest, 'September Wonder' was a great choice for an early maturing apple strain," Fallahi said.

Outcomes also showed wide variations in apple peel color among those strains categorized as both 'low-coloring' and 'high-coloring'. For example, the scientists determined that the fruits of 'Autumn Rose', 'Myra', and 'Top Export' always had less red color, while 'September Wonder' and 'Desert Rose' had more red color.

The authors deemed 'Desert Rose' a good choice for a late-maturing 'Fuji' strain based on the apple's excellent color, great storability, and shape.

"'Myra' was particularly desirable for its attractive pink color, resembling bagged 'Fuji' without the expensive cost of labor associated with bagging," Fallahi said. The authors recommend against planting 'Autumn Rose' because the strain produces muddy colored fruit under growing conditions like those in the study.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
