DETERMİNATİON OF THE EFFECT OF SİLİCON FOLİAR APPLİCATİON ON THE QUALİTY AND POST HARVEST RESİSTANCE OF SWEET CHERRY

Abstract
Sweet cherry is a very sensitive fruit, it is essential to ensure quality fruit production during the cultivation stage. It is possible to prevent fruit loss by increasing the quality of the fruit and post-harvest strength, in sweet cherries, with pre-harvest applications during the cultivation stage. During periods of harvest and post-harvest, the use of silicon can have a positive effect on fruit quality. In this study, calcium silicate (Ca2SiO3), potassium silicate (K2SiO3), and silicon dioxide (SiO2) were applied thrice to the cherry trees, at doses of 5 mM, 10 mM, and 15 mM, which would permeate through the leaves in the fruit set. Measurements and analyses of the sweet cherry fruits were carried out during and after the harvest, after a shelf life of two days. The other sweet cherry fruits were stored using modified atmosphere packagesing (MAP), at 0 ± 0.5°C and 90%–95% relative humidity for 2 and 21 days, and the fruit quality characteristics were determined after a shelf life of two days. In this study, the weight and size of the fruit increased with silicon application. The 10 mM Ca2SiO3, 5 mM and 10 mM SiO2 treatments particularly, increased the fruit size, as also the fruit width. Total soluble solids (TSS), titratable acid (TA) amount, and total phenol content in the fruits increased with the applications. In cherry fruits, coloration progresses during ripening, with a decrease in C* and h° values. The chlorophyll (chl) content in the leaves increased with the application of silicon K2SiO3 also it increases fruit firmness. Silicon application in cherry cultivation increases the fruit’s weight and size, especially 5 mM and 10 mM SiO2 applications, which have been determined to have a significant effect on fruit weight and size, the amount of total soluble solids and phenol content.
