Collection and Exchange of Seeds

Col­lec­tion of woody plants

About 1600 taxa belong­ing to 181 genus and 61 fam­i­lies are locat­ed on the ter­ri­to­ry of three den­dro­log­i­cal gar­dens, in the park, at the intro­duc­tion nurs­ery and oth­er col­lec­tion sites.  Taxa of dif­fer­ent ori­gin are duplicated.

Park

There are more than 50 thou­sand spec­i­mens of woody plants, 215 species and 26 taxa of sub­species rank from 29 fam­i­lies, 69 gen­era in the park. The ter­ri­to­ry of the park is locat­ed in the streets of Novorossiyskaya, Kar­by­she­va, B.Sampsonievsky prospect, and a rail­way embank­ment along Per­viy Murin­sky prospect. There are 2 parts of the park with­in its bound­aries: the west­ern and the east­ern ones, which are sep­a­rat­ed by the Insti­tut­sky Lane.  The area of ​​the park, exclud­ing the area of ​​den­dro­log­i­cal gar­dens and the zone of respon­si­bil­i­ty of the eco­nom­ic ser­vice, is about 40 hectares.  The ter­ri­to­ry is open, suf­fer­ing from large anthro­pogenic load.

Den­dro­log­i­cal gardens

The col­lec­tion of woody plants  numbers1119 taxa (927 species and 192 taxa of sub­species rank), belong­ing to 51 fam­i­lies and 142 gen­era.  The col­lec­tion is most wide­ly rep­re­sent­ed in the Upper Den­dro­log­i­cal gar­den: 899 taxa (139 gen­era and 50 fam­i­lies), which makes up 80% of the total col­lec­tion fund.  Woody plants of the Red Books of Rus­sia, Leningrad region, Kare­lia are rep­re­sent­ed in the col­lec­tion by 31 species, belong­ing to 23 gen­era and 18 families.

Intro­duc­to­ry nursery. 

The area of the nurs­ery is 0,63 hectares.  It is here that the pri­ma­ry tests of species and forms of woody plants which are new for the North­west Region are car­ried out in order to study their dec­o­ra­tive prop­er­ties and eco­nom­ic val­ue.  The main task is the intro­duc­tion of woody plants in order to pre­serve and improve the col­lec­tion.  2023 sam­ples of woody plants are being test­ed, which are the rep­re­sen­ta­tives of 64 fam­i­lies, 191 gen­era, 1019 species, 306 vari­eties, forms, sorts.

Col­lec­tion of open soil orna­men­tal herba­ceous plants

Cur­rent­ly, there are about 3000 taxa belong­ing to 435 gen­era and 100 fam­i­lies, being grown on col­lec­tion sites and open-air flower beds, and some grow nat­u­ral­ly in the park and den­drosades.  The flo­ra of wild plants is 227 species, belong­ing to 153 gen­era, 44 fam­i­lies (Ignatie­va, 1994).  Of undoubt­ed inter­est are spe­cial­ized col­lec­tions.  Col­lec­tions of gener­ic com­plex­es: astil­ba, lilies, daylilies, iris­es, phlox­es, ros­es, clema­tis, chrysan­the­mums.  Col­lec­tion of plants for shady areas.  A group of tall plants.  Plants of Siberia, the Cau­ca­sus, the Far East, Kare­lia.  Work is under­way to cre­ate expo­si­tion sites.

Col­lec­tion of trop­i­cal and sub­trop­i­cal plants

The col­lec­tion con­sists of 1,176 taxa (903 species and 273 taxa of sub­species rank) from 135 fam­i­lies and 403 gen­era.  In the col­lec­tion there are 11 fam­i­lies of high­er spore plants rep­re­sent­ed by ferns and 10 fam­i­lies of gym­nosperms.  The most wide­ly rep­re­sent­ed are the depart­ment of Mag­no­li­phy­ta, Mag­no­lip­si­da class of 81 fam­i­lies, 232 gen­era, 679 taxa.  Lil­iop­si­da class includes 32 fam­i­lies, 129 gen­era, 407 taxa.  A sig­nif­i­cant place in the col­lec­tion is occu­pied by the plants of the arid regions of the globe: the Cras­su­laceae fam­i­ly which includes 24 gen­era and 187 taxa, Cac­taceae (27 and 82), Agavaceae (7 and 34), Aizoaceae (11 and 24).  The most com­plete fam­i­lies are: Araceae (17 and 59), Bromeli­aceae (16 and 42), Are­cacea (12 and 27), Com­meli­naceae (10 and 35).

COLLECTION AND EXCHANGE OF SEEDS

One of the main tasks of the Botan­i­cal Gar­den is col­lect­ing and exchange of seeds, the pub­li­ca­tion of the exchange cat­a­logue of seeds “INDEX SEMENIUM”.  For the first time the list of seeds offered for the exchange by the den­dro­log­i­cal gar­den of the For­est Insti­tute was pub­lished by V.N.  Sukachev, E.L.  Wolff, G. Anufriev and A. Shen­nikov in 1928. It includ­ed 173 species and forms of woody plants.  The mod­ern cat­a­logue of seeds offered for exchange includes more than 700 types of woody and herba­ceous plants.  From sys­tem­at­ic point of view, the delec­tus includes species belong­ing to 80 fam­i­lies.  The largest num­ber of species is rep­re­sent­ed by the fol­low­ing fam­i­lies: o Rosaceae — 97, o Capri­fo­li­aceae — 49, o Aster­aceae — 27, o Pinaceae ‑20, o Oleaceae — 19.

Cur­rent­ly, 418 botan­i­cal insti­tu­tions are list­ed in the data­base of botan­i­cal gar­dens. Reg­u­lar exchange of delec­ta, appli­ca­tions and seeds is car­ried out with 197 botan­i­cal gar­dens. The geog­ra­phy of the exchange is exten­sive — 43 coun­tries locat­ed on 4 con­ti­nents.  The most inten­sive exchange is car­ried out with the botan­i­cal gar­dens of Ger­many, the USA, Italy, France, the Czech Repub­lic.  The inter­est of for­eign and domes­tic botan­i­cal insti­tu­tions in the exchange of seeds with the Botan­i­cal Gar­den of the For­est Tech­ni­cal Uni­ver­si­ty does not decline.
