Abstract
The study investigated the discriminant interpopulational variability of the morphological characteristics of Silver fir (Abies alba Mill.) from central Bosnia. Four morphological characteristics of the cone, six characteristics of the seed, two characteristics of the cone scale, and certain quotients of the cone traits, were investigated. Variability was investigated by the application of multivariant analysis of five populations which differ by geological and pedological parent rock, different phytocoenoses and which belong to different seed zones.
The investigated morphological characteristics of the cone, seed and cone scale of Silver fir (Abies alba Mill.) in populations of central Bosnia displayed significant individual, as well as interpopulational variability. Differences in altitude, pedological and geological soil structure between the populations had no effect on interpopulational variability of the investigated characteristics, or on the distance between populations. Statistically significant difference between populations, and their five relations, was determined for three out of four investigated morphological characteristics of the Silver fir cone. Five investigated morphological characteristics of the seed of Silver fir showed statistically significant interpopulational variability. One of the two investigated morphological characteristics of the cone scale, i.e. the length of the scale, showed statistically significant interpopulational variability. According to the discriminant analysis populations are grouped in three separated groups. Cone characteristics show the best separation, as well as seed characteristics in the discriminant analysis, while the characteristics of seed scales show less separation. Investigations of the characteristics of the cone, seed and scales could not be statistically correlated with age, d b h and height of the trees from which the samples were collected.
