## 2 Results and Discussion
### Correlation between Physicochemical and Sensory Attributes  
Linear correlation of physicochemical parameters of the four cherry cultivars with sensory attributes is presented in Tables 8-11. As mentioned previously, due to the small number of experimental observations, the results are only indicative, awaiting further verification with data to be collected during the upcoming harvesting year. For the Canada giant cultivar, it is seen in Table 8 that flavour showed a strong positive correlation to texture and colour and a strong negative correlation to pH and TPC. Texture showed a moderate positive correlation to TA, a strong negative correlation to pH, TPC and a moderate negative correlation to TSS. TA showed a strong negative correlation to pH and a moderate negative and positive correlation to TPC and colour respectively. In turn, pH showed a strong positive correlation to TSS and TPC and a strong negative correlation to colour. TPC showed a strong negative correlation to \begin{table}

Furthermore, there was a very strong negative correlation of TA to TSS and a very strong positive correlation of texture to colour. For the Ferrovia cultivar, it is seen in Table 9 that pH showed a strong positive correlation to colour.
