Eucommia ulmoides Oliv. seeds’germination depending on the methods of preseeding preparation

The article discusses the techniques, methods and results of Eucommia ulmoides Oliv. soil germination determination. Two batches of seeds collected from plants in various places of growth during introduction (Botanical gardens of Sochi and Sukhumi) were studied. The seeds' under snow storage, stratification in a refrigerator with the subsequent sowing of seeds in open ground was carried out. After stratification of seeds from Sukhumi their soil germination increased from 11.1% to 18.5%, i.e. almost 1.7 times. It was noted that the soil germination of Eucommia ulmoides seeds is directly depended on their mass while the seeds' sizes were of subordinate importance.
