The spruce forests of the “Tsentralno-Lesnoy”, “Kologrivsky les”, and “Bassegi” nature reserves are represented by typical spruce associations of the Russian Plain in its eastern part. The study of these forests is very important in terms of mold diversity. Such study in the territory of the “Tsentralno-Lesnoy” reserve was carried out in the late 1980s through visual assessment and does not meet modern requirements. On the territory of other reserves such studies were not conducted at all.
The article presents the results of studying the structure of spruce populations in the reserves using a metric and well-tested technique for assessing the shape of seed scales (this feature is largely due to genetic factors). The variability of this feature was studied on a large experimental material by collecting cones with 100 or more trees on each plot, in different types of forest.
In the reserves “Tsentralno-Lesnoy”, “Kologrivsky les” and “Basegi”, located at a great distance from each other from west to east, there are great differences in the phenotypic structure of spruce populations. In the “Tsentralno-Lesnoy” reserve there was a significant predominance of phenotypic specimens of European spruce (67%), individuals of intermediate phenotypes (73%) prevail in the “Kologrivsky les” reserve, and individuals of the Siberian spruce phenotype (86%) prevail in the “Basegi” reserve. On the territory of these reserves, there is a different proportion (33, 73, 14%, respectively) of individuals of intermediate spruce phenotypes.
The results of the study are new information on the phenotypic structure of spruce populations in the reserves and methods of its study.
