Pears

By Beatrice Dobie

The East Mailing Research Station have been working on stocks for pears for some time, but the root stocks available at present do not cover so wide a range of vigour as do those of apples.

Latterly Prunus cerasus has been used as a stock, which is said to have a more dwarfing effect, while the Mahaleb was also used for bush and fan-trained trees, and particularly with the acid cherries. The effect of Mahaleb is, however, unpredictable.

Unfortunately, there are varieties of pear which cannot be grafted successfully on to quince stocks.

There is unfortunately no really dwarf cherry tree stock, though work in this connection is proceeding at the East Mailing Research Station.

Since Jan. 1960, I have found that apricot seedlings are a possibility. There seem to be no special classifications as done for apples and pears, cannot be produced.

Research Station tell me that the chief root stock for pears is now Quince A. Quince B. is not now used and all the Commercial Supplies of Quince C. are virus infected and cannot be recommended until a newly selected virus-free clone has been released in sufficient quantities. - 15266
