Peculiarities of Reproduction of “Pinus nigra” Arn. in Ukraine

Abstract

The article analyzes the peculiarities of black pine reproduction and identifies the most promising methods of propagation for the territory of Vinnytsia city (Ukraine). Having analyzed the germination capacity of the black pine seed material, we found that the percentage of seed germination ranged from 38% (courtyards) to 70% (“Podillya” botanical garden). Examining the duration of black pine seedlings emergence, we found that in almost all objects of the city the largest number of seedlings were established on the 7th day (about 35 pcs.), then the process declined, and the smallest number appeared on the 13th day (about 5-7 pcs.). Studying the black pine propagation by cuttings, we found that when fed with two different rooting stimulants, the best result was obtained with the application of Korenevin (48 pieces), and a slightly lower acceptance rate was demonstrated with the use of Epine (about 34 pieces).
