Research into the potato tuber at the Basque Institute for Agricultural Research and Development and at the NEIKER-Tecnalia Technology Centre has, in recent years, focused on the development of new varieties of potato adapted to Spanish agro-climatic conditions. The Basque technology center has updated the traditional system for improving strains of the tuber by involving novel techniques that enable obtaining new varieties that are the most resistant, productive and apt for both fresh...

By Culley, Theresa M Hardiman, Nicole A The Callery pear (Pyrus calleryana Dcne. [Rosales: Rosaceae]), an ornamental tree from China, has begun appearing in disturbed areas throughout the United States.

Cultivated varieties (cultivars) of this species sold in the United States originate from different areas...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
