Genetic Variation and Phenotypic Plasticity of Quercus robur Populations and Open-pollinated Families in Lithuania

摘要: The purpose of the study was to estimate among- and within-population variation for juvenile growth rhythm traits, bud flushing leaf colouring, in open-pollinated families Quercus robur L. from six Lithuanian populations under different environmental conditions. Assessments were done nursery up 4 yrs, after replanting three field trials at age 6 yrs. A highly significant population effect found flushing. Large family variance components estimated height. family×site interaction more pronounced cessation height than Depending on trait, 13 33% contributed significantly interaction. Strongly site×population only Families with early taller, although correlation weak. Correlations between means parent trees...
