This is one of the most misunderstood types of fruit trees. Many were the reasons which led the Greek producers to this conclusion. Originally, the sporophytus pear tree Pyrus Communis was used as a rootstock, which is very vulnerable to the prime enemy of the pear tree- the bacterial burn Erwinia amylovora. So, during the 1980's many pear farms were destroyed and in consequence suspision towards the cultivation arose. The difficulties that came up trying to fight the flea of the pear tree - Psylla pyri - combined with the geotechnicals' ignorance to support the cultivator regarding the proper fertilizing and plant protection, only made things worse.
All the above reasons led the pear cultivation in our country to be limited to 60.000 tones, while at the same time in our neighbouring country Italy more than 900.000 tns are produced and in Spain 500.000 .
The pear tree is a fruit tree with many peculiarities both in the fertilizing method and in the general abjustment in various types of soil. Over the past years it has been grafted to quince rootstocks as they require slight vinegary, sour soil and not cohesive one. With the introduction of new preparations, solutions were found in treating the flea and the other enemies of the cultivation. The most common varieties in Greece are Krystalli, Kontoula and Williams. Meanwhile worldwide the Conference variety comes first, followed by Abate Fetel. Before planting pear trees in a farm the procedure of soil analysis, the recording of the mechanical composition, of the pH and of the quantity of the active calcium carbonate, are of vital importance. Furthermore, a very crucial part in the successful choice of a rootstock plays the soil conditions, always taking into consideration the phenomenon of disagreement between many of the pear varieties with the frequently used rootstocks.
