We review the specificity of early and late phenological types of pedunculate oak differing in the spring flushing of leaves, namely, its occurrence in topographical elements, soil conditions and hydrology, responses to weather, and vulnerability to unfavorable factors. We show that phenological forms differ in a set of morphological and physiological indicators, growth energy, and peculiarities of the wood. We focus on the importance of the phenological specificity of planting materials when organizing oak plantations with regard to ongoing climatic changes and the ubiquitous decline of oak forests. The late form of oak is more preferable in most cases, because it is more resistant to spring frosts and insect damage, as well as the fact that it has higher quality wood in solid-volume trunks.
