К биологии арборифлоры Приморского края

In the study of Primorsky Region arboriflora in its relation to important factors of the environment, i.e. light, moisture, heat and conditions of wintering is considered. The specification of its biology is necessary for silvicultural, introductive and planting trees and undergrowth practices. The arboriflora of Primorye is rather uniform in relation to these fac-tors of the environment within low-mountain and mid-mountain high-rise zones. It is established that modern biota of middle mountains of Primorye was geologically recently mountainous. The scale of shade tolerance of tree species accepted in the work by A.L. Korkeshko (1952) was enriched with views of Primorsky Region unaccounted earlier. So, in the scale of photophility on the first places it is more logical to put subalpine vegetation (cross-coupled microbiota, to Sabine Dahurian both its seaside subspecies and a cedar tree). Behind a juniper firm - a juniper firm seaside subspecies (creeping), a juniper Siberian and a dense flowered pine. After an ilm mountain (№ 18, A.L. Korkeshko) or together with it should place lindens and Wolf's lilac. The list of the trees, bushes and lianas on de-crease of their insistence is provided to moisture. It is noted that the most photophilous bushes, unde-manding to soil fertility, xerophit, and mezophit, gigromezophit and gigrophit have increasing shade tolerance. The type’s markers of climatic optimum on increase of the sums of active temperatures, heat and dryness are distributed. The places of normal growth of winter-hardy and not winter-hardy types are defined. The types having wide ecological areas are listed. The list of wood views long-livers of Primorsky Region is provided. For gardening formation of the range from representatives of local flora should begin: 1) from determination of fea-tures macro- and microclimate of the area and con-crete site, leaving the possibility of using of ever-green forms in the conditions of snowless winter; 2) from studying of illumination, moistening, oppor-tunities of regular watering; 3) from the establish-ment of the features including richness of the avail-able soils and water penetration of the subsoil hori-zons.
