For ‘Opal’ no significant differences were found between the different rootstocks.
The amount of flower clusters per tree varied between years, which are
common for the ‘Opal’ cultivar. However, for the rootstock Ferlenain higher amounts
were registered in the fifth and sixth leaf. No clear differences were found between
the dates for flowering between the different rootstocks.
