This study had three objectives: (1) to teat the hypothesis that multiple flushing of the terminal shoot (intermittent growth pattern) in Douglas-fir seedlings (Pseudotsuca menziesii var. menziesii) has an adaptive significance, especially in inland populations from the drier regions in southwest Oregon; (2) to evaluate the genetic and adaptive consequences...
A comparative intraspecific karyotype analysis was performed on European black pine (Pinus nigra Am.) seed sources (countries) by examining root tip meristemic cells of young seedlings (two weeks old). By a combination of Feulgen and Aceto-carmine staining methods, metaphase chromosomes range (12.93 ± 1.33) seedlings from two to three seed...
In this dissertation we consider the problem of
