INTRODUCTION FEATURES OF RED OAK (QUÉRCUS RÚBRA) IN MARI EL REPUBLIC
06.00.00 Agricultural sciences
DescriptionThe 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
