The propagator of scions or grafts applies for certification of his propagation material. The certification body checks the plausibility of the information provided. During the vegetation period, it checks the varietal purity, varietal typicity and health status of the mother vine stocks used for the production of scions and the vine nursery areas on which the grafted vines are cultivated. Furthermore, the certification body checks the quantity and quality of the sorted and bundled goods before placing the scions or grafts on the market.
