Rootstocks

The quince tree has been used over the past 25 years as a pear rootstock, aiming not only to the control of the vividness of the orchard but also to the increase of the productivity. Some of the quince tree alterations do not coordinate well with some pear varieties, that's why the prior grafting to the Buerre Hardy variety is used. In other circumstances, though, the philoshophy changes, so we use rootstocks of the OHxF series like the OHxF 40 to solve the problem of the disagreement and that of the iron chloriation in carbonate soil, where the quince tree cannot be cultivated as a stock.

 

QUINCE TREE A (E.M.A)

This is a choice  of the East Malling Institute of England. It is of a medium vigor around the 70%  of the sporophytus. It coordinates well with many varieties apart from the Williams. In the area of Tyrnavos it is considered as a good rootstock for the Krystalli variety.

QIUNCE TREE C ( E. M. C )

Also found in the East Malling Institute. Quite nano- dwarf stock, 55% of the sporophytus. It is ideal for dense cultivation. Nevertheless it does not coordinate well with the Kontoula and Santa Maria varieties. It is sensitive to chloriation.

BA 29

It comes from France where it was discovered by Bois L' Abbe in 1963. It is quite vigorous of 75% of the sporophytus. It is one of the oldest rootstocks used in Greece. Due to its disagreement with many pear varieties it has started being abandonded.

ADAMS QUINCE TREE

It belongs to the stocks group of Province, originated from France. It is a rootstock of medium vividness of 65% of the sporophytus. It is quite resistant to moist soil and at the same time the most resistant to the iron chloriation. It coordinates well with all the pear varieties. Poultsidis Nurseries has brought to notice that it is the most ideal rootstock for Greece, compatible with all the varieties with the exceptions of the Williams and the Highland.

ROOTSTOCKS OHxF

They come from the United States of America and they derive from the sporophytus of the pyrus communis pear tree. The series of these stocks include a variation of choices of the OHxF with different types of vividness accordingly. The OHxF 333 is one of the most vigorous stocks, which means that the tree bears fruit at a slow pace while the fruit is not of a satisfying size. The OHxF 40 rootstock appears to be the most dominant of all, as its agronomical characteristics are desirable- for example it is of 70% dwarf, it has strength in soil with high proportion of CaCO3, it also coordinates well with all the pear varieties, it comes to a quick  production with satisfying fruit size and lastly it is suitable for dense cultivation. The whole series of the rootstocks is regarded as resistant to the burning bacteria. Nevertheless, the last characteristic unfortunately does not pass to the variety with the highest rate of bacteria attacks.
