FAROLD®87 Daytor* (OHF 87)
The majority of commercial pear trees are grown on rootstocks. Pear rootstocks impart such characteristics as vigor, precocity, disease resistance and cold hardiness. The rootstock OHF 87 may impart dwarf characteristics as 70% height compared to normal classical tree.
OH stands for “Old Home”, a name given to a seedling selection discovered in Illinois by Prof. F.E. Reimer of OSU. The “F” stands for Farmingdale, the town in Illinois where Reimer discovered the second Bartlett selection. Old Home and Farmingdale were crossed by L. Brooks of Oregon and the resulting offspring were fireblight resistant, self-fertile, vigorous and had good cold hardiness, making it desirable as a rootstock and receiving a patent in 1960.
Main features of OHF 87:
- A very good affinity with varieties such as red William’s, conference and all pear varieties in general;
- Resistance to chlorosis;
- Resistance or an excellent tolerance to the decay of the pear tree and to bacterial blight;
- Less sensitivity to extreme temperatures than the quince tree;
- A significantly better affinity than with quince trees, even for difficult varieties;
- Its productivity is high without affecting the caliber. In fact, its growth in vigor is well managed by the fruit set. This is a very good asset for the cultivation of the pear tree.
OHxF 87™ is considered as a semi-dwarf tree;
OHxF 87™ is one of the best producing rootstocks of the OHxF series and was selected for this very reason;
OHxF 87 should be planted 6-8′ between trees within a row;
It gives early vigor and is more precocious than OHxF 97;
It is not good for interplanting with less vigorous trees due to competition for light.
