Abstract

The sunlight manipulation can be utilized to promote the desired plant physiology by using photoselective nets. In our study, we tested different colored nets to determine the physiological responses of the strawberry plant. The study was conducted in 2016 at Selcuk University in Turkey. A strawberry (Fragaria x ananassa Duch.) cv Kabarla was used in the study planted in 7 L pots. Before the shading treatment, all plants were grown outdoors. For the shading experiment, sunlight was declined by red, green and black nets allowing 40% shade with covering from July until September of 2016 (during 2 months). At the end of the experiment, some physiological and microclimate properties were evaluated. The green net showed the highest SPAD value (39.79), while the lowest value was obtained in red net (34.99). The photoselective nets increased anthocyanin compared to control. Stomatal conductance in the red colored net decreased by approximately 38% when compared to full sunlight. The lowest soil temperature was observed under green colored net. Colored nets increased air temperature compared to control. As a result, the mitigative effect of the photoselective nets against radiation could be used to decrease the malignant effects of environmental stresses such as drought, excessive solar radiation, salinity.
