C points, that is, isolated points of circular polarization in transverse fields of varying polarization, are classified morphologically into three distinct types known as lemons, stars, and monstars. These morphologies are interpreted here according to two natural parameters associated with the singularity, namely, the anisotropy of the C point and the polarization azimuth on the anisotropy ax...

In the hilly area of Gioia Tauro (Calabria, Southern Italy), lemon orchards are grown in consociation with centuries-old olive trees. Lemons partially shaded by canopies and microclimate at level their is suitable for plants growth quality productions. Under these conditions, trees even without irrigation, providing, despite this limitation, a product. This study aimed to i) investigate qualita...
