CENTURY-OLD SIBERIAN STONE PINE CROPS GROWTH AND PRODUCTIVITY IN THE ZONE OF CONIFEROUS-BROADLEAVED FORESTS OF THE MIDDLE VOLGA REGION

abstract 1311707097 issue 131 pp. 1168 – 1180 29.09.2017 ru 149
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.

INTRODUCTION FEATURES OF RED OAK (QUÉRCUS RÚBRA) IN MARI EL REPUBLIC

abstract 1231609094 issue 123 pp. 1368 – 1378 30.11.2016 ru 316
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
