Research to prevent double fruit formation depending on climate change on cherries

This study was carried out at the experimental areas of both Adana (subtropical) and Pozanti (highlands) Agricultural Research and Application Center during 2012 and 2016. ‘Prima Giant’, ‘Brooks’ and ‘Early Burlat’ cherry cultivars were experimented in Adana.
In Pozanti location, ‘0900 Ziraat’ cherry cultivar was also experimented besides the other cherry cultivars.
The aim of the project was to prevent double fruit formation by using shading system, fogging, kaolin applications and the combinations of these techniques.
Shading + fogging and shading + kaolin combinations gave the most effective results on decreasing the temperatures and double pistil formation.
The application of only shading, fogging and kaolin were also more effective than control to decrease the temperatures and the amount of double pistils.
The best values for the photosynthetic parameters were obtained from shading + fogging application.
The photosynthesis speed was measured to be 14.45 µmol CO₂ m^‑2 s^‑1, stoma conductance was 177.7 mmol m^‑2 s^‑1, PSII (Fv’/Fm’) was 0.74 and SPAD value was 42.60 µmol m^‑2.
