Abstract

When growing container planting material of English oak, it is necessary to ensure high soil germination, which can be achieved by sorting seed material, optimizing its storage conditions and preparing acorns for sowing. The article presents the results of assessing the influence of storage methods, the timing of sowing acorns, their pruning and the composition of the substrate on soil germination and dimensional indicators of container oak seedlings. When comparing the methods of storing acorns in trenches and barrels in cold stores, a slight advantage of the first method was revealed. The average value of germination for storage in a trench was 48.5%, for storage in a refrigerator 45.9% when sown in May, 53.8 and 52.2%, respectively, when sown in June. There was no effect on dimensional indicators. The introduction of an additional amount of fertilizers and dolomite into the composition of the substrate can contribute to an increase in the biometric parameters of seedlings. The use of pruning acorns increases soil germination within 2.0–2.4 times. With an increase in the intensity of pruning, soil germination increases, but the size of planting material decreases. Sowing cropped acorns at the end of July allows to grow standard material, provided it is in a greenhouse until hardening.
