Serbian spruce (Picea omorika /Panc./Purkyne), as the Balkan Peninsula endemic and the Tertiary relic, is a species whose survival is threatened by the constant restriction of its range caused by the global changes of environmental conditions and the adverse human impacts. The Serbian spruce seedling seed orchard at Godovik represents the base for the improvement of the production of the selected seeds of this species, which can be used as the initial material for the extension of its range. The allele polymorphism of the mitochondrial nad1 gene was analyzed in five different Serbian spruce phenogroups of which the orchard is established. The obtained results are a contribution to a closer study of the causes of the postglacial intraspecific differentiation of Serbian spruce and the creation of the above phenogroups. The study results are significant for further breeding of this species based on the better knowledge of the genetic structure of the species, its directed utilisation and the widening of its range. .

The aim of this paper is to analyze the effect of different degrees of mixing on the diversity structure in stands left to spontaneous development. The research included two communities of species endemic to the Balkan Peninsula—the Serbian spruce (Picea omorika Pančić Purk.) and the Macedonian pine (Pinus peuce Griseb). Data from eight sample plots were used in the research. The changes in diameter and height structure, spatial arrangement of trees, and diameter differentiation were analyzed. The analyzed parameters of structural diversity show relatively low to moderate values. Results showed an increase in mixing was reflected in the width and shape of distributions. A spatial analysis of stands with a higher degree of mixing showed a tendency towards a random to regular distribution of individuals, in contrast to stands with a lower degree of mixing which showed a tendency towards a clump distribution. The pronounced species’ dimensional and spatial diversity confirms their importance to the condition of modern forest management. Significant differences in the change of structure are shown by stands with a share of admixed species of above 20% by volume. The obtained results refer to stands left to spontaneous development, suggesting than an active research and management approach must be assumed to realize the goal of protecting rare forest ecosystems.

The presented model for the establishment of an experimental clonal seed orchard of Serbian spruce was designed based on the results of the analysis and assessment of the genetic potential of Serbian spruce seedling seed orchard at Godovik. Based on the results of the analyses, eight superior half-sib lines of Serbian spruce were selected, of which 24 genotypes were selected. Their hybridisation, by the model of incomplete diallel cross resulted in 21 combinations at the level of half-sib lines, i.e. 48 combinations at the level of parent genotypes. The applied study methods identified the potentially valuable genotypes-cone producers i.e. pollinators, which will be fixed by cloning in the seed orchard of the second generation for the production of the promising hybrids.

Picea omorika (Panc) Purkyn? (Serbian spruce) is a Balkan endemic coniferous species. We studied soluble peroxidase, catalase, polyphenol oxidase, and superoxide-dismutase activity in the needles of five omorika lines grown in a generative seed orchard. The peroxidase and polyphenol oxidase isoenzyme patterns were also investigated. Activity of the studied enzymes varied among different lines. The highest activity of peroxidase, catalase and polyphenol oxidase was found in the A3 ("borealis") and B5 ("semidichotomous") lines. Four acidic and two basic peroxidase isoenzymes and one polyphenol oxidase isoenzyme were detected. There was no variation in either the peroxidase or the polyphenol oxidase isoenzyme pattern among the different lines.

The Impact

Serbian spruce (Picea omorika (Pančić) Purk.) is an endemic tree species from the Balkan Peninsula. The species also thrives in Slovenia and would be an interesting minority alternative to Norway spruce (Picea abies (L.) Karst.) on some sites. This study was carried out in a Serbian spruce plantation below Počivalnik hill, between Unec and Postojna. The trees were planted in 1988 and are currently classified as a pole stand. We measured the diameters of the trees and systematically evaluated the vitality of each tree throughout the plantation. Data processing consisted of calculating the percentage of trees of each health status for each provenance and phenotype present in the plantation, creating a plantation model, and performing an analysis of variance and Tukey's post-hoc test. We found that provenance has a significant effect on the vitality of trees but not on tree diameter. Phenotype affects both the vitality of trees and tree diameter. The correlation between phenotype and tree diameter is significant within phenotypes B (type %semidichotomy%) and C (type %serbica%). Also, the impact of phenotype on diameter increment varies between the different provenances. According to our investigations, the most suitable seed material for the Dinaric karst region of Slovenia is from the Šargan provenance (read Shargan). In terms of phenotype, types C ('serbica') and F ('argentea') seem to be the most suitable. They are also the most desirable for horticultural use.

The effects of the climate characters and climate index calculated by Thornthwaite-Mather method on diameter increment of Austrian pine trees in the seedling seed orchard on Jelova Gora was studied in the period from 1996 to 2002. The samples for dendrometric analysis were taken from 498 trees in 40 half-sib lines originating from the best natural sites of this species. A strong correlation was determined between the range of precipitation regime and Thornthwaite-Mather climate index, and the development of current diameter increment. The study results indicate that the diameter increment of Austrian pine increases considerably with the increase of humidity, regardless of the relatively modest demands regarding the site productive characteristics.

Serbian spruce (Picea omorika /Panc./ Purkyne) is rare and endangered tertiary relict and endemic species in the Balkan Peninsula. Its natural distribution is fragmented and restricted to western Serbia and eastern Bosnia and Herzegovina, mainly in the canyon of middle course of the Drina river. Since the mid-19th century, the number and size of populations have been steadily decreasing accompanied by a decline in the number of mature individuals, endangering natural regeneration is endangered. The objective of this study is to determine variability within Serbian spruce (Picea omorika /Panc./ Purkyne) natural population in the canyon of the Milesevka river on the basis of morphological and anatomical characteristics of needles and, thus, to broaden knowledge on this rare and endangered species. Twigs with needles collected from all mature individuals that represent the population were used as material for the study. The following morphological and anatomical characteristics were measured: NL- needle length; NH - needle height; NW - needle width; CT+EH - cuticle + epidermis height; HH - hypodermis height; VB - vascular bundle diameter; No of SC - number of resin channels; SC diameter - resin channel diameter. The average values of the measured characteristics are: needle length 13.23 mm; needle width 1239.93 ?m; needle height 608.63 ?m; cuticle + epidermis height 11.49; hypodermis height 17.59 ?m; vascular bundle diameter 220.64 ?m; number of resin channels 0.74; resin channel diameter 52.36 ?m. The characteristics with the highest variability are as follows: number of resin channels (161.64%); resin channel diameter (25.35%); hypodermis height (20.79%), while the needle width is a characteristic with the lowest variability (6.39%). The results of the analysis of variance showed very high statistical differences within population for all studied characteristics (p<0.01; ?=0.05). In order to make the results clearer, it is necessary to investigate the genetic diversity and population structure by analyzing various phenotypic characteristics in specially designed experiments (e.g. progeny tests) as well as by analyzing appropriate DNA markers. The studied population must be involved in continuous conservation and breeding processes, especially through appropriate forms of ex situ conservation.

Pine (Pinus merkusii) is tree species that provides timber and gum rosin. To meet the needs of wood and non wood (gum rosin) products, planting by using superior or high quality seeds are needed. Seed procurements for planting are obtained from seedling seed orchard (SSO). However, Cijambu’s SSO was attacked by pine woolly aphid (Pineus boerneri). Therefore, assessment of Cijambu’s SSO needs to be done to evaluate the severity pest attacks that could affect to the quality and the quantity of seed production. Forest Health Monitoring (FHM) method is one of the methods to assess the health level of a stand. The number of trees found in all cluster plots in Cijambu’s SSO were 270 trees. Based on the value of the VCR (Visual Crown Rating), the trees located in all cluster plot have health level between low to high. Based on the value of the VCR showed 38.52% (104 trees) having VCR’s value was high, 49.26% (133 trees) having VCR’s value was middle; 12.22% (33 trees) having VCR’s value was low; and no tree having very low VCR’s value. The average of VCR’s value in all cluster plots were 3.25 and classified as middle health. Based on the value of TDLI (Tree Damage Level Index) from 270 trees in all cluster plot showed that 189 trees (70.00%) in healthy condition; 69 trees (25.56%) in slight damage condition; 11 trees (4.07%) in middle damage condition; and 1 tree (0.37%) in heavy damage condition. The value of damage in all cluster plots (ALI) was 261.22 and classified as in health condition. The trees located in all cluster plots were mostly suitable to be seed sources as 242 trees (89.63%), while 28 trees (10.37%) were not suitable for seed sources.Keywords: Forest Health Monitoring, Pinus merkusii, seedling seed orchard, Tree Damage Level Index, Visual Crown Rating

The study was carried out in Serbian spruce (Picea omorika Panc/Purkyn?) plantations in the western Serbia. The paper presents results of the analysis of crown development. The following elements were analyzed: total tree height, height of the crown base, absolute and relative crown length, maximal crown diameter, coefficient of crown spreading and degree of crown girth. We discuss approaches to the modeling of tree crown growth and development, growing under favorable environmental and stand conditions, without anomalies in development. In order to establish the relationship between analyzed factors, regression analyses were applied. Data fitting was by the analytic method, by the implementation of Prodan?s functions of growth, linear and parabolic function. Received models can be used for the simulation of various growth and developing processes in forest.

A program of provenance testing, seed production and genetic improvement of jack pine was developed in the Baskatong region of western Quebec through sustained collaboration among government forest services and forest industry. Research plantations demonstrated, within a period of 10 years from establishment, the superiority in growth, cold hardiness and disease resistance of regionally adapted local seed sources. Critical differences were evident between provenances from the Boreal Forest Region and those from the adjacent Sections of the Great Lakes — St. Lawrence Forest Region.A 300-acre (120 ha) seed production area was created within a genetically superior jack pine population of natural origin in the Côte Jaune area west of Lake Baskatong. Within this population, 325 plus trees were selected, marked and recorded over two years by student crews employed in the summer. Seed harvested from the felled plus trees will be used to create a seedling seed orchard and to establish progeny tests. The plus trees are to be grafted for controlled breeding among selected progeny-tested clones at a later date. This cooperative program of tree improvement will ensure the future supply of high quality seed that will maintain and enhance the value of the forest resource.
