The copy number of DNA matrices of subcellular organelles (plants) can serve as an indicator of the intensity of photosynthesis and oxidative phosphorylation processes. We assessed the relative copy numbers (RCN) of mitochondrial and chloroplast DNA in young and mature leaves of three grape varieties: ‘Traminer Pink’, ‘Chardonnay’, and ‘Syrah’, grown under field conditions. Leaf samples (5–10 mg) were randomly selected from each group of plants for subsequent total DNA extraction. The qRTPCR rea
