Birch-leaved Pear
Birch-leaved Pear, from planting, is 24 years old [2]
The three minor noble hardwood species are important from an ecological as well as from an economical point of view. They are growing in mixed hardwood forests, often at the margins of forest stands due to competition for light. In mixed hardwood stands with beech as a major component thinning usually favours the minor Noble Hardwood species in order to prevent heavy competition and to reach sufficient size for an economically interesting utilization.
Birch-leaved Pear bark & blossoms
Pyrus communis pear cultivars are self-incompatible, hence in these orchards inter-fertile cultivars have to be planted. Parry (1976) and Kurennoi (1985) screened the following Pyrus species as potential pollinators: Pyrus amygdaliformis, P. longipes, P. nivalis, P. salicifolia P. betulaefolia, and P. syriaca.

At the INRA Angers Research Unit research into pollinators for pear varieties was initiated in 1990. A selection from Pyrus betulaefolia, the P337-41 clone, was subsequently selected as the best candidate. This genotype exhibits very abundant flowering, and a regular and extended blooming period. The latter covers the blooming time for early to late pear varieties. The clone P337-41 originating from Pyrus betulaefolia is recommended as a pollinator for the main varieties grown in France: ‘Williams’, ‘Conférence’ and ‘Doyenné du Comice’. [1]

The cultivation of the pear extends to the remotest antiquity. Traces of it have been found in the Swiss lake-dwellings; it is mentioned in the oldest Greek writings, and was cultivated by the Romans.
