Optimizing the Technologies of Initiation and Restoring Oak Forests by Applying Physiological Methods

The research goal was to elaborate a method of obtaining pedunculate oak (Quercus robur L.) seedlings with a high growth rate and increased resistance to extreme temperatures, thus reducing the costs of plantation care works during the first years after their initiation and the risk of suppression of oak plants due to competing with fast-growing weeds.As a result of the provided research, we elaborated a method of initiation to pedunculate oak forests, including two separate stages.In the first stage, the collected October acorns, after treatment with the biostimulator Reglalg, are incubated in specially created laboratory conditions for acorns germination and plantlet growth until May.In the second stage, the five-month seedlings are transferred to the field for cultivation.In the first, second, third, and fourth years of cultivation, the seedlings height reached 52, 95, 120, and 176 centimeters, respectively.During the mentioned periods, plants grown from the sown in the field acorns reached a height of 7, 19, 24, and 31 centimeters, respectively.Taken together, the obtained result gives the possibility to conclude that, during the first four years, the growth rate of the pedunculate oak plants, grown by a newly elaborated method, was at least five times higher.The plant's tolerance to high temperatures was also higher than those of the plants obtained after the ordinary method (by acorns sowing in the fall).
