Introduction
There are more than 150 species wild fruits and berries belonging to the 15 families and 36 generas in the forests of Azerbaijan. Their composition is rich in various vitamins, microelements, proteins, fats, sugars, acids, in a word, with many essential elements useful for human organisms. From this point of view, wild fruits do not fall behind cultivated fruit types and sometimes they are superior from them. One of the wild fruits is the species pear belonging to the genus Pyrus L. grown in our forests. 27 species from them are grown in the Caucasus.
There have been shown 18 species of pears in the flora of Azerbaijan (Fedorov, 1954), 2 species of them (P. serotina Rehd. and P. communisL.) have been cultivated in cultura and four species (P. elata Rubtz., P. voronovii Rubtz., P. raddeana Woronow, P. complexa Rubtz.) are believed to be in the territory of Azerbaijan.
Because of researches conducted by T.H. Talibov and A.M. Ibrahimov (Ibrahimov, 2007; Talibov & Ibrahimov, 2009; Talibov & Ibragimov, 2009;) there have been identified 17 species and 3 variations of wild pear have spread in the territory of Nakhchivan Autonomous Republic.
Methods
In order to clarify the current situation of the representatives of Pyrus L. in the Azerbaijan Republic flora, there have been given attention to the herbariums kept at their Herbarium Fund of the Botany Institute of Azerbaijan National Academy of Sciences, Bioresources institute of Nakhchivan branch of Azerbaijan National Academy of Sciences, Nakhchivan State University, there have also been comparative analysis of herbarium samples concerning of organizations and various Institutions placed on their web sites. There have been determined the content of the Pyrus L. genus fulfilling of field expeditions during 2004-2017.
"Trees and shrubs of Azerbaijan" (Bandin & Aliyev, 970), "Higher plants of Azerbaijan" (Askerov, 2006), "Flora of Azerbaijan" (Fedorov, 1954), "Trees and shrubs of the USSR" (Fedorov, 1954), Areas of trees and shrubs of the USSR" (1980), "Flora of the Caucasus" (Grossheim, 1952), "Dendroflora of the Caucasus" (Sahokiya, 1965), "Flora of the USSR " (Maleev, 1939) and other modifiers V.N. Gladkova (1987, 1990), Talibov & Ibrahimov (2008) had been utilized for determining of species.
Results and discussion
The available taxons which have been discovered by A.M. Ibragimov and T.H. Talibov, at the same time new pear species for Azerbaijan and the Nakhchivan AR are as follows:
1. Sectio: PashiaKoehne. 1893, Deutsch. Dendrol: 244: emend. Terpo 1960. Ann. Acad. Horti-Viticult. 22. 6. 2: 30-32.
1. P. boissieriana Buhse. it is tree or bush, the height is up to 5 m. The fruit is smaller, the diameter is 1 -1,5 cm. It is spheric, shiny, and red; the flower is in arising flower-group, with a stalk of 4 cm. The fruit is rapen in the month of August-September. It has been spread in the mountain forest of Astara and Lankaran, on the edges of the glade.
2. Sectio: Pyrus L. 1753, Sp. Pl. 1: 479.
2. P.grossheimiiFed. It is a tall bush or tree, the length is 10-12 m, the diameter is 12-16 cm. The fruit is smaller, the diameter is 2 cm, is sphere or partially oblongated. It is spread mainly in the forests and the edge of forests of Talish (Leryk, Shuvi, Penser, Bendesar) (Fedorov, 1954). It is a rare plant and its natural reproduction is very weak, so it needs to be replicated and reproduced.
3. P. hyrcana Fed. It is a tree, the height is 16 (25) m. Bark is dark grey coloured, young shoot is white, with small lentils, thornless. The fruit are found individually or umbrella gangs, hollow sphere, the diameter is up to 3 cm, cinnamon coloured. Natural reproduction is poor, there are 6-8 different aged young adults in 1 hectare. It has spread in the Bandasar region of Lankaran and Astara, in mountainous and foothill forests areas around Masalli, Istisu, Shuvi, Perenbel, Khocabar, Burdtala (Fedorov, 1954).
4. P. caucasica Fed. The height is 25 m, oblongated, oval or conical conopy, diameter is up to 60 cm. It has got a broad spread areal and the most well-known pear species. It has been noted in the Caucasus. It has been noted in the work of "Flora of Azerbaijan" (Fedorov, 1954) that species have spread in the Greater Caucasus (Guba region) in the eastern, western, central and northern regions of Lesser Caucasus. It has been indicated on literature data (Prilipko, 1954; Asadaov et al., 2001) that species have spread in the forest of Bichenek of Shahbuz region of Nakhchivan AR. However, the spread areas of the species have been revealed on the investigations carried out by T.H. Talibov and A.M. Ibrahimov (2007).
It has been determined that P. caucasica Fed. species are spread in large areas y of the Kuku, Bichanek of Shahbuz region, in the surroundings forest of the Nurgut, Nasirvaz and Gildachay villages of Julfa region (1800-2200 m above sea level). Also, in the studies of T.H. Talibov and A.M. Ibrahimov (2007), there have been shown the spreading of new variation of P. caucasicavar. schuntukensisTuz. in the Shahbuz region (1900-200 m above sea level). The P. caucasicavar. schuntukensisTuz. variation have been determined according to the specimen of the herbarium specimen from the Shuntuk river basin (350 m above sea level) in 1966 by A.S. Tuz (Tuz, 1972).
As P. caucasica Fed. has been grown in the wetlands, but also has a high fruit yield. Indigenous people gather and use this species fruit enthusiastically. Natural restoration is sufficient.
5. P. vsevolodiHeideman. The tree is about 5 m. The fruit is spheric pear formed, the diameter is 1.8-2.0 cm. Firstly, it is netted hairy, as growing up became naked, the fruit stalk is thick, hairy, is longer 1.5 to 2 times than fruit. It grows at the edge of the near the Altiaghac village of the Khizi region (Fedorov, 1954).
6. P. demetriiKuth. It is a tree of a gray shell and spheric canopy, the height is 6-7 m. The shoots are grey-red-shelled and naked, with long thorns. The leaves are lancet form, the height is 4-7 (8.5) cm, the width is 1.2-1.6 (1.8) cm. The surface of leaf is bright green, bare, and the bottom side is pale green, slightly hairy along the middle vein. Drying time is becoming relatively dark. Fully or poorly vivid toothed, becoming sharpen at the end. The stalk is 1.5-2.5 cm in length and it is naked. The fruits are oblated from the poles, are naked and the lenght is 2.2-2.5 cm and diameter is 2.5-3.0 cm. The ripen fruit is brown. The thicker fruit stalk is 1.5-2.0 cm height. The pulp is very solid and hardened, it is a mouth-astringent.
The species have been collected by Sh.i. Kutateladze for the first time in 1947 (Kutateladze, 1947) and determined based on herbarium specimens.
There have been shown that, P. demetrii Kuth. species have found in sparse forest as individually or along with oak, hawthorn, and other species of pear in the Nurgut village of Ordubad region and Bichenek village of Shahbuz region by T.H. Talibov and A.M. Ibragimov (Talibov & Ibragimov, 2009). It is a new species for the flora of Azerbaijan, as well as Nakhchivan AR.

7. P. zangezura Maleev. It is a thornless tree, height is up to 9-10 m, with scattered canopy. The branches are grey, immature shoots are dark brown. The leaves are wide; scalpel or oblongated egg-shaped, blunt or sharp pointed, the edges are blunt arched toothed. The fruit is in the bunch group with 7-8 numbers. There have been supposed to be found in the adjacent territories to Zangazur in Azerbaijan on the literature information (Bandin & Aliyev, 1970; Fedorov, 1954).
T.H. Talibov and A.M. Ibragimov (Talibov & Ibrahimov, 2007) confirmed that existence of P. zangezura Maleev. species in the flora of Azerbaijan, as showing that this species had grown at 1900-2000 m above sea level, the area called "Serkhanbichen" in
the Shahbuz State Nature Reserve of Nakhchivan AR._

The size of fruit is small, the length is 2-3 cm and width is up to 2 cm. There have been shown being spread only in Bichanak area of the Shahbuz region of Nakhchivan AR on the literature data (Gurbanov, 1996). However, during the investigations carried out by T.H. Talibov and A.M. Ibrahimov (2007) in addition it has been revealed that, this species has spread in the forests of Nesirvaz and Nurgut villages of the Ordubad region, along with the hawthorn species or individual form at the altitudes of 2000-2200 m above sea level, it has been shown that it is finished in only one of the most accessible areas.

The species have been included to the flora of Nakhchivan and Azerbaijan by T.H. Talibov and A.M. ibrahimov for the first time (2007).
P. psuedosyriaca Gladkova species has widely spread in the forest, riverbank of Bichenek region of Shahbuz region and Nurgut village of Ordubad region of Nakhchivan Autonomous Republic.
It grows at the edges of the glade, forests along with the oak, apple, cherry, hawthorn and other species of pear (P. syriaca and P. nutans) at an altitude of 1800-2000 m.
10. P. raddeanaWoronow. As showing have been not spreading in the flora of Azerbaijan, it was supposed that the species to be found on the border areas in Karabakh with Zangilan (Bandin & Aliyev, 1970; Fedorov, 1954).
It is thornless tree, the height is up to 5 m, the length of leaves is up to 6.0-8.0 cm in and the width is 2.0-4.0 cm, oblongated, ellipse-shaped. The leaf stem length is 3.0-4.0 cm and fluffy. The fruit is smaller, sphere shaped, the fruit stem is longer 2 times from fruit. Drought-resistant, less demanding of soil. It flourishes in April, and its fruit ripens in July-September. There is no information on natural rehabilitation.
The new spread area of P. raddeana Woronow have been determined by T.H. Talibov and A.M. Ibrahimov (2007) that, this species have found in the forests of Badamli, Kuku villages of Shahbuz region, Akhura and Havush villages of Sharur region and as in the case of rarely on the dry stony slopes of mountainous slopes of mountains (1800-2000 m altitude above sea level).
11. P. acutiserrrataGladkova. It is a low-height tree, the bark of the young branches is grey-brown-colored. The lenght of leaves are 5.0-8.0 cm, the width is 2.0-3.0 cm, the broad lancet or scalpel shaped, blade is leather form, edges are sharp toothed, but leaves on sterile branches are full-fledged. It is dense hairy on the upper and lower sides. The leaf stem is about 2-4 cm, hairy. The fruit is located as individual or minor subgroups. It is a spheric pear form, the fruit stalk is sparse hairy, the length is 2.03.5 cm.
P. acutiserrata Gladkova species have been collected by G.A. Denisova and determined in accordance with the sample stored in Herbarium (LE) of St Petersburg (Leningrad) of Russia from the surround of garden and sowing area near the village of Badamli in the Shahbuz district of Nakhchivan AR, abandoned by V.N. Gladovka (Gladkova, 1987) in 15. VII. 1954. T.H. Talibov and A.M. Ibrahimov (2007) have noted that this species has spread individually or in groups around the villages of Badamli and Kuku villages and low mountain range of the Kuku Mountain of Shahbuz region.
12. P. eldaricaGrossh. It is a bush, the length is 1.0-1.5 m. The trunk is intensely thorny. The leaves are small, oblong or rhombic form.

13. P. syriacaBoiss. The height is 10-12 m, it is a sturdy thorny tree. In the flotation of Azerbaijan (Fedorov, 1954) It have been shown that this species has spread in Bichanak span of Shahbuz region of Nakhchivan AR in the flora of Azerbaijan Republic. In the study, it was noted that, except of the Bichenek and Batabat zones, this species has also grown in the wide area of the forest field of surround of Nasirvaz and Nurgut villages of Ordubad district (5, pp. 27).
14. P. voronoviiRubtz. It is a tree, the height of the P. voronovii Rubtz. is up to 8-9 m, the bark of the young branches is grey-brown and thorny.

The fruit is oblated on both sides, the size in 2.5x3.0 cm, and the stem of fruit is 2 cm. It flourishes in April-May and its fruit ripens in August-September.
It is supposed founding in the adjacent territories to Zangazur in Nakhchivan AR and Karabakh on the work of "Flora of Azerbaijan" (Fedorov, 1954).
During the investigations carried out by T.H. Talibov and A.M. Ibrahimov (2007), assumption about of P. voronovii Rubtz. was in truth by the fact of new founding. It has been determined that species have spread in the forest and bushy areas called "Serkhanbichen" and "Cheperbashi" in the Shahbuz State Nature Reservation between 1900-2100 m heights, with oak, hawthorn, apple and other species of pear.

It grows on dry mountain slopes of small Caucasus, in Gobustan, in the mountainous and plains of Samur-Shabran region. These species are found in Nakhchivan AR in 1100-2200 m altitude area, in dry mountain slopes and rocks, in the valleys of the river individually or in groups (Talibov & Ibrahimov, 2007).
Though it has been shown that P. salicifolia Pall. species has spread in Nakhchivan AR by L. Prilipko (19, pp.109), but it has not reflected in the "Flora of Azerbaijan" and "The Treess and the Bushes of Azerbaijan". Further it has been shown about availability of P. salicifolia Pall. species in Nakhchivan AR territory by E.G. Gurbanov (Gurbanov, 1996).
K.S. Asadov and A.K. Asadov (2001) show the availability of P. salicifolia Pall. in the forest of Bichenek. It is mainly reproduced with root shoots.
In the researches conducted by T.H. Talibov and A.M. Ibrahimov, there have been given information on the wide spreading of var. latifolia Alexenko and var. angustifolia Kuth. variations of P. salicifolia Pall. species in the territory of the Autonomous Republic.
16. P. medvedeviiRubtz. It is a tree, the length is 10-20 cm long. The leaves are reverse lancet, the lehgth is 9.0-11.0 cm, and the width is 3.0 cm. The fruit is green, as pear form. The fruit stalk is long and felty hairy. It is spread on rocky and dry mountain slopes of Nakhchivan AR.
The spread area of the species has further been clarified by T.H. Talibov and A.M. Ibrahimov (2007). It has been revealed tha t, P. medvedevii Rubtz. species have mainly spread in the near of the Jamaldin village of Julfa region the area called "Almemmed piri", as individually in Bichenek forest and on dry rocky of Lisbirt valley (surround of Karakush mountain) of Babek region.

The size of the fruit is smaller, the diameter is 1.5 cm, oblongated, the fruit stalk is up to 1.5-2.0 cm, felted hairy.
P. oxyprion Woronow have not been noted in the books of "Flora of Azerbaijan" (1954) and "Trees and shrubs of Azerbaijan" (1970). L.I. Prilipko (1939) and E.M. Gurbanov (1996) have showed that this species has been found in Nakhchivan AR. T.H. Talibov and A.M. Ibrahimov (2007) have showed that P. oxyprion have been found in area of Sirab village of Babak region, at the surroinding area of Bichenek and Ayrinc villages of Shahbuz region, on the stony slopes of Kukudag, on the slopes of Ardij mountain of Sharur region.

It is a new species for the flora of Azerbaijan and as well as Nakhchivan.
Conclusions
It has been revealed that currently 21 species of wild pears belonging to the Pyrus L. genus are known in the flora of Azerbaijan. 17 species of them have been spread in the area of Nakhchivan Autonomous Republic. Pyruszangezura Maleev., P. voronovii Rubtz., P. georgica Kuth., P. demetrii Kuth., P. fedorovii Kuth., P. psuedosyriaca Gladkova., P. chosrovica Gladkova., P. megrica Gladkova, Pyrus caucasicavar. schuntukensisTuz., P. salicifolia var. angustifolia Kuth., P. salicifolia var. latifoliaAlexenko species have been first given for the flora of Azerbaijan and Nakhchivan Autonomous Republic.
Thus, Pyrus grossheimiiFed., P. eldaricaGrossh., P. boissieriana Buhse, Pyrushyrcana Fed. and Pyrus vsevolodiiHeideman pear species have been taken from the flora of Azerbaijan have not been notted in the flora of Nakhchivan AR. In turn, P. zangezura Maleev., P. psuedosyriaca Gladkova., P. megrica Gladkova., P. demetrii Kuth., P. chosrovica Gladkova, P. acutiserrata Gladkova, P. fedorovii Kuth. pear species that newly founded and notted in the flora of Nakhchivan have not been found in the other regions of Azerbaijan. P. serotina Rehd. and P. coomunis L. pear species have been cultivated traditionally. As a result of the influence of climatic and anthropogenic factors on the territory of the Autonomous Republic in recent years, there has also been a threat to the destruction of a number of precious species of wild pear genefund in nature. As a result of the investigations (Ibrahimov, 2008) considering of Pyrus boissieriana Buhse. (CR A2 abc; C1), P. eldarica Grossh. (CR A2 abc; C1), P. grossheimii Fed. (CR A4 cd; C1), P. hyrcana Fed. (CR A2 abc; C1), P. salicifoiia Pall. (NT), P. vsevolodii Heideman (NT) species rareness and endangered have been included to Azerbaijan (Red Book of the Republic of Azerbaijan, 2013), P. medvedevii Rubtz. (NT), P. syriaca Boiss. (NT), P. zangezura Maleev. (VU B1 a(i)c(ii); C2a(i)), P. raddeana Woronow (VU B1 a(i)c(ii); C2a(i)), P. voronovii Rubtz. (VU B1a(i)c(ii); C2a(i)), P. megrica Gladkova (VU B1a(i)c(ii); C2a(i)) species have been included to the Red Book of Nakhchivan Autonomous Republic (Talibov & Ibrahimov, 2010).
From them P.eldarica Grossh., P. boissieriana Buhse and P. hyrcana Fed. species have been included to the The Red Book of Azerbaijan USSR (1987) that published in 1989 and P. raddeana Woronow species to the former Soviet Union's Red Book (Red book of the USSR, 1984).
Recent findings show that pear species in Azerbaijan should be investigated more thoroughly and determined their natural reserve and tons of pear fruit that remained without use should be directed to production.
