garden of Peter the Great. There are 27 taxa of pines (Pinus), reperesented by 82 trees, in collection of Peter the Great 
Botanic Garden of the Komarov Botanical Institute RAS (Saint-Petersburg), the oldest of them being up to 125 years 
old. Pinus peuce, P. koraiensis and P. sibirica are the most widely distributed.The tallest tree are 25,0 m high 
(P. strobus). They reach the trunk diameter up to 68 cm (P. strobus).The pride of collection being such rare species 
from Eastern Asia as P. densiflora and P. densata. The Dwarf Siberian pine (P. pumila) was firstly introduced into 
general cultivation from here. There are 17 species which produce cones. There are species promising both for 
repeated (P. edulis Engelm, P. rigida Mill., P. thunbergii Parl.), and primary introduction (P. arizonica Engelm., 
P. culminicola Andersen et Beaman, P. henryi Mast.). The continuous monitoring on winter hardiness as well as on 
steadiness to pests and diseases is necessary, which is especially true in conditions of the global warming of the 
climate. The investigation of reproductive abilities, quality of seeds and of seed reproduction is of importance. 
This is necessary to involve the best species and forms into city planting and forest economy.
