Abstract
Leaf morphology of the grapevine (Vitis vinifera L.) cv. ‘Kövidinka’ was evaluated based on 32 landmarks. The aim of this study was to reveal leaf morphological diversity along the shoot axis. For this purpose 10 shoots were collected with 26 to 35 leaves. Altogether 304 leaf samples were digitised and analysed with the GRA.LE.D 2.04. raster graphic software. Leaf damage was estimated based on the missing landmarks on the lamina. Our results showed that the leaves on the 11<sup>th</sup> and 13<sup>th</sup> nodes are the most intact, without missing landmarks. Lowest variability (c<sub>v</sub> = 0,126) of the investigated 54 morphological characteristics were observed among the leaves on the 11<sup>th</sup> nodes of the shoots, in accordance with the literature. Based on the results length of the veins, angles between the veins and further features such as size of the serrations show high diversity along the shoot axis. These results underline the need of careful sampling during the ampelometric investigations.
