Before the grapevine starts to “wake up”, experts on grafting came to visit our greenhouse. They grafted our uninfected grapevines with buds of virus-infected grapevine by using the “chip budding” grafting method. The success of viral transfer will be determined in two months.

After grafting, pots were reorganized in groups containing one plant from every treatment. The pots will stay in this organization until the end of the experiment.
