CHLOROPHYLL CONTENT IN STRAWBERRY LEAVES PRODUCED UNDER SHADING SCREENS IN GREENHOUSE

The strawberry culture (Fragaria × ananassa Duch.) is one of the most widespread fruit production in the world and its consumption is increasing in the last years in Brazil, since it is a good source of natural antioxidants compounds.
For this reason, new technologies have been searched in order to obtain higher productivity as well as improved product quality.
Shading screens with colors were used to produce different spectrum of transmittance in the visible band, where the blue, metallic and red colors can be found and are the most employed.
In this study, we investigated the effects of colored nets on total chlorophyll (Chl), and Chl a and Chl b in the leaves of two strawberry cultivars (‘Camarosa’ and ‘Oso Grande’) in protected environment ambient.
Cultivar ‘Camarosa’ showed higher concentration of Chl a, b and total than cultivar ‘Oso Grande’. Nevertheless, the use of red, blue or metallic screens did not affect the contents of chl.
Finally, the Chl b concentration was higher than Chl a, in both cultivars grown under colored net screens or ambient light.
