Pollen index and temperature are the main factors influencing olive production

07.01.2009
A study from the University of Cordoba and the University of Castilla-La Mancha (Spain) determines that the annual pollen index (PI) and the maximum temperature in March are variables influencing most the annual olive crop in Castilla-La Mancha.

The olive fruit production of olives shows considerable annual fluctuations; therefore, it is of great interest to know the most influencing parameters on the final harvest and to have an approximate estimation.

Knowledge of the main biological and climate factors influencing final harvest is becoming increasingly necessary in order to obtain reliable crop estimates and, thus, ensure optimised, effective private crop management. Effective olive crop forecasting is essential in optimising human and economic resources for olive-fruit harvesting, marketing strategies and global commercial distribution.

A study carried out by scientists from the University of Cordoba and the University of Castilla-La Mancha has identified the main factors influencing olive fruit production in this region. In the research, thay analized data from ten years, including atmospheric pollen as an index of flowering intensity, and meteorological data over the flowering and fruiting seasons. Castilla-La Mancha (Central Spain) is the second largest olive-oilproducing region in Spain, the highest olive-oilproducing country in the world.

They reported that the pollen emitted during the whole pollen season (pollen index) was the variable influencing most the final olive crop. The main meteorological variable in the region during the development of flowers was the maximum temperature of March. Also, it has been revealed that the rainfall registered during the final phases of fruit growing (October) also has a positive influence on the harvest.

This paper has been published in 2008 in the Aerobiología magazine; and has been written by Herminia García-Mozo and Rosa Perez-Badía (University of Cordoba) and Carmen Galán (University of Castilla-La Mancha).

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
