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: MPSD team discovers light-induced ferroelectricity in strontium titanate

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.

Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...

Researchers at TU Graz calculate the most accurate gravity field determination of the Earth using 1.16 billion satellite measurements. This yields valuable knowledge for climate research.

The Earth’s gravity fluctuates from place to place. Geodesists use this phenomenon to observe geodynamic and climatological processes. Using...

Im Focus: Tube anemone has the largest animal mitochondrial genome ever sequenced

Discovery by Brazilian and US researchers could change the classification of two species, which appear more akin to jellyfish than was thought.

The tube anemone Isarachnanthus nocturnus is only 15 cm long but has the largest mitochondrial genome of any animal sequenced to date, with 80,923 base pairs....

Im Focus: Tiny light box opens new doors into the nanoworld

Researchers at Chalmers University of Technology, Sweden, have discovered a completely new way of capturing, amplifying and linking light to matter at the nanolevel. Using a tiny box, built from stacked atomically thin material, they have succeeded in creating a type of feedback loop in which light and matter become one. The discovery, which was recently published in Nature Nanotechnology, opens up new possibilities in the world of nanophotonics.

Photonics is concerned with various means of using light. Fibre-optic communication is an example of photonics, as is the technology behind photodetectors and...
