Abstract
In the European fruit growing the rootstock PILLNITZER ‘SUPPORTER 4’ (‘Pi 80’) is being propagated more and more, in recent years.
It will prove useful for intensive and semi-intensive growing systems, but not for super intensive plantations.
The rootstock may replace M.26 in regions where M.9 is impossible to use.
Details of PILLNITZER ‘SUPPORTER 4’ are shown below:
