The aim of this study was to examine the development and aging of chosen grapevine leaves in situ during the growing season (130 d) using chlorophyll (Chl) a fluorescence measurements and determining the changes in pigment contents. During the course of photosystems development, the increase of Chl and decrease of anthocyanin contents in leaves was observed simultaneously. On 28th day, the maximum content of Chl and minimum content of anthocyanins was measured. However, the maximal photosynthetic performance was found one week later, when the content of Chl started to diminish. Our study proved that the achievement of maximal...
