Rootpac® 20
The series of Rootpac patterns comes from the programme for obtaining new Prunus rootstocks developed between 1996 and 2012.
The search for these patterns focused on responding to the needs of a fruit sector in constant evolution and development towards the efficiency and intensification of plantations.
