In spite of their wide geographic distribution, the various species in the genus Pyrus are intercrossable without major incompatibility barriers. Also, the high morphological diversity and the lack of distinguishing characters among the species have been reported. Therefore, the classification of species in this genus is problematic and often confusing, giving different populations designated as different species by some authors. It is likely that, when the genus is reviewed, there will be several changes to the nomenclature[
Pyrus hajastana is a deciduous tree
The plant is harvested from the wild for local use as a source of materials.
This species is found at only four locations and the number of mature individuals is falling because of wood extraction for fuel and small timber. The plant is classified as 'Endangered' in the IUCN Red List of Threatened Species(2013)[

Species in this genus generally prefer a good well-drained loam in full sun[
]. They usually grow well in heavy clay soils. They tolerate light shade but do not fruit so well in such a position, tolerate atmospheric pollution, excessive moisture and a range of soil types so long as they are moderately fertile[
]. Established plants are generally drought tolerant[
The wood is of good quality. Generally of small dimensions, it is used for making small items[
The wood is used for fuel[
Seed - best sown in a cold frame as soon as it is ripe in the autumn, it will then usually germinate in mid to late winter. Stored seed requires 8 - 10 weeks cold stratification at 1°c and should be sown as early in the year as possible[
]. Temperatures over 15 - 20°c induce a secondary dormancy in the seed[
]. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in light shade in a cold frame or greenhouse for their first year. Plant them out in late spring or early summer of the following year.
