The research purpose was estimate of the red oak
growing suitability in Mari El Republic. To achieve
this goal we investigated experienced 44-year-old red
oak plantation at the Botanical garden-Institute,
determined acorns morphological characteristics of red
and English oaks and seedlings grown from them. The
evaluation of red oak plantings identified excess of
average height and tree diameter in comparison with
English oak, but the sanitary condition of both oaks
forests was weakened due to the influence of the
complex of unfavorable factors. Morphological acorns
evaluation showed that the shape factor of acorns of
English oak is equal to 1.64, while the red oak is 1.1.
Biometrics parameters of red oak bareroote seedlings
in the field were higher than English oak bareroote
seedlings. In greenhouse biometric parameters of red oak container seedlings had not excess. According to
this research, red oak is recommended for use in
landscape construction in Mari El Republic
The purpose of the study was to examine a century of
experience of growing of forest cultures of the
Siberian stone pine in forest conditions in the region of
the Middle Volga. To achieve these objectives, we
have investigated old growth culture of Siberian stone
pine in the conditions of fresh oak forests in the
territory of Rootka forestry of the Mari El Republic.
Culture of Siberian stone pine was planted after
continuous tillage. The distance between rows was 2,5
m, step landing – 1,0 m. The site was divided into five
options, depending on variations in the width of
planting strip (I-48 m, II-44 m, in III-40 m, IV - 36 m,
V - 32 m). The studies have shown that the Siberian
stone pine trees, regardless of the variant, are
characterized by good clean ability from twigs, which increases with decreasing of the width of the curtain. It
can be noted that in the 100-year-old age, the average
height of trees reaches of 28,7 m, an average diameter
of 49,8 cm. Stock of forest reaches 795,3 m3
/ha. Best
annual increase is observed in growing cultures of
cedar in the wings with a width of 40 m and is 7,95-of
7,93 m3
/ha. Based оn the research, we have concluded
that Siberian stone pine should be recommended for
introduction into the zone of coniferous-broadleaved
forests of the Middle Volga region. When creating
crops, it is necessary to use larger seedlings and plant
density is not more than 1,0 thousand pieces/ha, and
the width of the planting strip shall be not less than
40,0 m.
