Biological potential of sea buckthorn productivity in natural and industrial stands in Russia

This article analyzes the area of natural growth of buckthorn in its main vegetation regions. The issues of raw stocks of sea buckthorn berries in natural stands are also considered. The article studies the components of yield in varietal stands of buckthorn in the climatic conditions of the Orel region. The authors managed to establish a high degree of fruiting in varieties, representatives of the Baltic climatype: Syurpriz Baltiki, ZHeltoplodnaya, Moryachka, Zolotaya kosa, Kenigsbergskaya, Serafima, within 13.3-10.5 kg / bush. Unstable or low yields were shown by varieties derived from the Altai climatype: both Karamelka (5.2 kg / bush) and Elita 8-51 2.5-2.8 kg / bush all other samples occupied an intermediate position. The authors noted that the indicators of the potential productivity of the variety are morphostructural components of productivity (berry weight, number of berries from 1 bud, number of flower buds that formed berries per unit shoot length, the number of fruiting shoots and their length), which are controlled by genotype, variable and depend on climatic factors, the physiological state of plants, age and immunity.
