Abstract:

Abstract Rotation-age growth performance of 16 provenances and local growth superiority were assessed from a rotation- age reciprocal coastal Douglas-fir [Pseudotsuga menziesii var. menziesii (Mirb.) Franco] provenance test established in the Pacific Northwest of America. Provenance differences for total volume per plot were highly significant. Due to the significant provenance × site interaction effect, the best provenances varied across planting sites in terms of rotation-age volume growth. Local provenance trees exhibited superior volume growth at two of the six planting sites. At the remaining four sites, local provenances performed equally well as average non-local provenances. At the three low-elevation (< 460 m) sites, low-elevation provenances performed significantly better than high-elevation provenances. By contrast, high- and low-elevation provenances had similar growth at the two high-elevation (> 800 m) sites. Southern provenances generally grew faster than northern provenances at the Oregon sites, while northern provenances performed better than southern provenances at the sites in British Columbia. Regression analyses showed that although local growth superiority increased with the geographic distance between provenance’s origin and the test site in general (r=0.47, P<0.001), it only became obvious when the geographic distance is larger than 435 km in latitude or 370 m in elevation. Significant spatial autocorrelation was found via Mantel test, and geographically or climatically closely located provenances tended to have similar rotation-age volume growth. The results suggested that breeding zones larger than the current second-cycle zones would lead to little loss of rotation-age total volume for coastal Douglas-fir in this region.

Abstract:

A research was conducted to determine genetic variability and structure of ebony either within provenances or within trees in the same provenance using isozyme analyses. Results of this study are expected to show genetic variability of ebony with different provenances. For the purpose of the study, five provenances of ebony (Maros,Barru, Sidrap, Malili, and Mamuju) were prepared. The isozyme analysis using electrophoresis was applied to determine the genetic variability. The obtained data were statistically analyzed using multivariate and dendrogram analyses with Numerical Taxonomy System (NTSYS) Program applying unwighted pairgroup method and arrithmetic average (UPGMA) approach. Results showed that the variability of genetic provenances of ebony were less than any other tree species. Among the existing provenances, Barru dan Mamuju showed higher genetic variability compared to other provenances. Ebony provenance was generally found to homozygously increase or to performinbreeding. The genetic variability of ebony was mostly derived from the variability in population (95.4%). Grouping individual trees based on their provenances indicated that Malili provenance showed closed relationship to Maros provenance, whilst Mamuju provenance showed closed relationship to Barru and Sidrap provenances.

Abstract:

Increased frequency of extreme weather events has seriously affected forestry operations in south-eastern Europe. A precondition for effective artificial restoration of disturbed forest stands is site-adapted forest reproductive material (FRM). Common garden experiments (provenance trials) may assist in selecting such FRM. The main objective of this study was to establish among-provenance variation pattern using data from a beech provenance trial. Usefulness of the results in selecting seed sources for restoration of European beech stands is discussed. The trial was set up in 2007, at a slope of Medvednica mount facing north-west at 730-750 m above sea level. Plant heights were measured and survival scored in 2008 and 2015. Height increments were calculated and processed to determine variance components due to various effects. Highly significant provenance-by-block interaction was revealed, indicating strong microsite effects on provenance performances. Therefore, corrections were made and provenance mean height increments recalculated. Provenance mean height increment multiplied with survival was used as a measure of a provenance’s adaptedness. Regression tree (RT) analysis was used to determine the pattern of among-provenance variations. A set of provenance clusters was grown using climatic variables related to the provenance stands of origin as criteria. All analyzed effects were significant (provenance: F=2.07, p<0.05; block: F=5.07, p<0.05; provenance by block interaction: F=7.32, p<0.001). Data corrections reduced the interaction effect, thereby increasing reliability of calculated provenance adaptedness indices (AI). Provenances were grouped into 4 clusters due to elevation, mean July temperature and summer heat-to-moisture index (SHM). Cluster 4, containing provenances from the highest altitudes (>750m), had the highest mean AI (143.9±8.4 cm). The lowest mean AI (106.7±14.8 cm) had cluster 1, containing provenances from lower altitudes with lower mean July temperatures (≤18.4°C). Provenances originating from lower elevations with higher mean July temperatures (>18.4°C) were further divided into two clusters due to the SHM variable. Cluster 2 had the second highest mean AI (141.2±1.5 cm) and contained provenances from relatively wetter habitats (SHM≤48.2). Cluster 3, containing provenances from relatively arid habitats (SHM>48.2), had significantly lower mean AI (116.8±8.6 cm). Established among-provenance variation pattern might be used as a tool in selecting seed sources for artificial restoration of beech stands at mount Medvednica. It is advisable to use FRM from higher altitudes and/or from slightly lower altitudes (up to 150 m lower than a restoring site) but featured with warmer and drier conditions compared to the trial. Generally, provenance trials should be utilized as a valuable decision tool in restoring disturbed forest stands but may also be misleading if not well designed and analyzed.

Abstract:

Due to projected global warming, there is a great concern about the ability of European beech to adapt to future climate conditions. Provenance trials provide an excellent basis to assess the potential of various provenances to adjust to given climate conditions. In this study we compared the performance of four European beech (Fagus sylvatica L.) provenances growing in a provenance trial at the Fruška Gora Mountain, Serbia. Three of the investigated provenances (Höllerbach and Hasbruch from Germany and Vrani Kamen from Croatia) originate from moist sites, with annual precipitation sums being twice as high as at the provenance trial in Serbia. The performance of these provenances are compared to the growth of the local provenance Fruška Gora which is well adapted to dry site conditions. We analysed tree-ring width, mean vessel area, vessel density and water-conductive area for the period from 2006 to 2012. In spite of differences in climate conditions at their place of origin all beech provenances showed a similar pattern in radial increment. Also the wood- anatomical variables showed similar inter-annual patterns for all provenances and no significant differences between the provenances. This indicates that beech provenances from moist environments can adjust to the relatively dry temperate climate in Serbia.

Abstract:

Tree size and aboveground biomass in twelve 34-year-old Ontario jack pine (Pinusbanksiana Lamb.) provenances growing at Petawawa National Forestry Institute (Chalk River, Ontario) was negatively correlated with latitude of origin. The best provenance exceeded the local provenance in tree height and diameter by approximately 10%. The pattern of geographical variation was stable over time, making general and sound predictions of provenance growth based on juvenile performance feasible. Persistent differences among some geographically close provenances indicated the potential for genetic improvement by selecting the best populations within site regions. The results demonstrated have important implications for jack pine breeding and improvement strategies at the provenance level. The provenance averages of aboveground ovendry weight per tree ranged from 44 to 79 kg. The aboveground tree biomass was distributed as follows in seven analyzed provenances: stem wood, 78%; stem bark, 8%; branch wood, 8%; needles, 5%; cones, 1%. Variation in average stemwood mass among provenances was less than the variation in average stem volume because of a strong negative correlation on a single tree basis between stem volume and stem wood density. The mean annual volume and biomass accretion per hectare in the best provenances averaged 10 m3 and 4 t, respectively. Total stem volume production per hectare varied exponentially with tree height. Mean annual stem volume increment of the best provenances exceeded that of the slowest growing provenances by 22–40%.

Abstract:

Fifteen coastal provenances of western hemlock Tsugaheterophylla (Raf.) Sarg. were tested on four sites on Vancouver Island, B.C. Provenance origins and test sites lay within roughly 2° of latitude and at 0–580 m above mean sea level. Mean heights of provenances 10 years after planting varied from roughly 74 to 121% of the plantation mean at each site; plantation means varied from 388 to 493 cm. No interaction between provenance and test site was detected and rankings of provenances remained quite constant from site to site. A large proportion of provenance variation could not be accounted for by descriptors of provenance origin. Results show that for the geographic range tested, faster growing provenances could be planted without constraints imposed by elevation and latitude.

Abstract:

AbstractA total of 420 individuals belonged to 18 native teak (Tectona grandis L.f.) provenances from all four distributed countries and 10 introduced provenances were analyzed to for genetic variation, structure and genetic origin using SSR markers. The unbiased gene diversity for each provenance ranged from 0.4692 to 0.8523 with a mean value 0.6612, showing high variation within teak provenances and variation in India provenances was highest than in other countries’ provenances.AMOVA analysis showed that the majority of variation existed within provenances (84.760%) and also substantial variation among countries (10.586%). As more as possible plus trees from large population should be selected or conserved in order to keep genetic variability for future improvement. Different countries populations should be preserved in the natural habitat or collected for ex site conservation with cooperation and region-wise strategies.A Mantel test revealed significant correlation between genetic distances and geographic distances of teak provenances (R=0.7355, P<0.001). The cluster analyses by UPGMA, PCA and STRUCTURE methods gave very similar results, showing India provenances were firstly differentiated, and Laos provenances clustered with Thailand provenances, then introduced provenances and Myanmar provenances successively joined in the clusters. The introduced provenances no. 19, 20, 22, 23, 25, 27 and 28 appeared to be very closely linked to Laos provenances (especially no. 17) and Thailand provenances (especially no. 5 and 6), while provenances no. 21, 24, 26 may be originated from Myanmar provenance (especially no. 16).

Abstract:

The distribution of pedunculate oak in Bosnia and Herzegovina is important in connecting the southern and eastern provenances of the Balkan Peninsula with provenances from Central Europe. However, due to over-exploitation, pedunculate oak is almost extinct in Bosnia and Herzegovina. This research aims to determine the heredity and production potential of the pedunculate oak from 28 provenances in the Bosnian-Herzegovinian provenance test through the genetic gain of thickness and height growth. The results will be used in selection of best provenances in terms of genetic gain. For this research, height and root collar diameter of pedunculate oak plants in Bosnian-Herzegovinian provenance tests were measured in 2012, 2016 and 2020. The provenance test was established in 2009. It contains 28 provenances from Bosnia and Herzegovina. Heredity and selection differential were assessed using analysis of variance. Possible genetic gain if using five best and one best provenance were determined. The results of the genetic gain for height obtained using data from 2012 and 2020 were low. The results obtained for 2016 indicate that the genetic gain for height, using five best provenances would be 7.62%, and using the best provenance 9.98%. Results of the genetic gain for root collar diameter obtained for 2016 and 2020 were low. For 2012, the genetic improvement using five best provenances would be 4.28%, and using the best provenance 6.32%. The results indicate that by selecting the best provenances of pedunculate oak and their propagation, we can achieve a significant increase in plant height and thickness, i.e., the yield of wood mass. As research concerns juvenile material, it is necessary to continue systematic monitoring, to determine the actual heredity and genetic age, when the trees reach their physiological maturity, and when the annual value oscillations become uniform.

Abstract:

Provenance tests of forest tree species are important experiments in silviculture and tree breeding. Their results provide information about provenances' growth, adaptability, and other features. The research aimed to determine the dynamics of growth and tree shape of common beech plants per provenances in the international provenance test in Bosnia and Herzegovina to choose the best provenances considering wood production and quality. Research was conducted in the provenance test containing eight provenances from Bosnia and Herzegovina, four from Germany, three from Serbia, two each from Croatia, Romania, and Switzerland, and one from Hungary. Provenance test was established in 2007 by planting 2-year-old and 3-year old seedlings. Height and root collar diameter were measured, and tree shape was assessed in 2019. Data were processed in SPSS 26.0. Descriptive statistics, variance analysis, multiple Duncan's test for all traits, and Pearson's coefficient of corelation among morphological traits and tree shape were calculated. Variance for the height and root collar diameter showed statistically significant differences among different ages of plants and among provenances. Provenance from Croatia (Dilj Čaglinski) had the highest, and provenance from Romania (Alba-Iulia) had the lowest average height. The highest average value of root collar diameter had provenance Dilj Čaglinski, and the lowest value had provenance Sihlwald (Switzerland). The highest percentage of category 10 (ideal tree form) had provenance Bad Wildbad (Germany), and categories 1-4 (no silviculture value) had provenance Alba-Iulia (Romania). Pearson's coefficient showed that height, root collar diameter, and tree shape are highly correlated. Considering all the above, when planning forest-breeding works, it is recommended to continue the research and favor provenances with the best growth and tree shape.

Abstract:

UDK 582.475:581.4(497.6 Olovo) The research has been carried out in a formal experiment with silver fir near Očevje-Olovo, with nine provenances originating from natural BiH population of 22 years of age. The research observed following provenances: communities from the area of Bugojno, Bosanski Petrovac, Olovo-Palež, Olovo-Klis, Pale, Konjic, Fojnica, Sokolac, and Prozor. The analysis of diameter on the root collar found that there are statistically significant differences among the provenances. It was also found that the biggest diameter on the root collar was on the provenances of Fojnica, with 75.6 mm, whereas the smallest was on the provenances of Olovo-Klis, with 65.2 mm. In terms of breast height diameter, some statistically significant differences were also found, so that the biggest diameter was on the provenance of Fojnica, with 47.0 mm, whereas the smallest value of this feature was on the provenance of Pale, with 41.6 mm. The analysis of the height of different provenances for the testing period, 1999 – 2005 (7 years), suggested statistically significant differences among the provenances. The biggest value was on the provenance of Bosanski Petrovac, with 407 cm, whereas the smallest height was on the provenance of Olovo-Klis, with 364 cm. The results obtained during this research provide valuable information, which can be used as indicators for successful differentiation of silver fir.

Abstract:

BELONGER, PAUL JAMES. Variation of selected juvenile wood properties in four southern provenances of loblolly pine. (Under the direction of Steven E. McKeand.)Gravimetric wood density, x-ray densitometry, and latewood tracheids were used to investigate the relative importance of genetic and environmental effects on various assessments of wood density, tracheid characteristics, and growth traits in loblolly pine (Pinus taeda L.). Breast-height wood samples were taken from four 12-year-old plantings of a genetics trial that included approximately 50 open-pollinated families of loblolly pine from diverse sources. The densitometry and tracheid analysis included wood samples from only two of the test sites and assessed variation in 51 families, and 38 families, respectively. Moderate provenance differences, but strong family and environmental differences were found for wood density and volume, and the pooled genetic correlation between volume and density was -0.30. The Atlantic Coastal and Lower Gulf sources had higher average wood density than the Marion County and Gulf Hammock sources, and the Lower Gulf source had the lowest stem volume. Provenance variation in wood density was not consistent with geographic trends indicating a need for field testing in the area of intended deployment. Location effects were very important and sites which promoted high volume production also appeared to cause low wood density. Strategies are available to combat the unfavorable negative environmental correlation (-0.91, P < 0.01) between stem volume and wood density. Provenance variation was important for disk densities of early ring segments, but diminished with age and was not significant (P > 0.10) beyond the segment consisting of rings 3-6. Pooled narrow-sense heritability estimates for the consecutive-ring group disk densities ranged from 0.142 to 0.225, and all groups were highly correlated with average (tree) disk density (rA > 0.90). Mean latewood density and mean latewood percent both showed a strong positive genetic correlation with average disk density and the disk density of the ring 3-5 segment. Early selection for disk density can be effective.The transition to "mature" wood occurred at ring number 5.9 at the flatwoods location with higher wood density and ring number 8.9 at the upland test site with lower density. The point of transition also showed a strong provenance component (P < 0.05); the higher density Atlantic Coastal and Lower Gulf Coastal Plain sources transitioned sooner than the lower density Gulf Hammock and Marion County sources. Trachied length, total diameter, lumen diameter, and cell wall thickness were measured using outer-ring latewood tracheids. Of the trachied traits, only cell wall thickness showed a marginal location effect (P < 0.10). Measured in the middle-third of the cells, tracheids sampled at the Florida location were about 11% larger in total diameter, lumen diameter, and cell wall thickness, but no difference was detected for tracheid length. Provenance differences were strongest for cell wall thickness (P < 0.01) and marginally important for tracheid length (P < 0.16) and total cell diameter (P < 0.18).Variation among families within provenances was large (P < 0.01 for all tracheid traits) and resulted in relatively high narrow-sense heritability estimates of 0.58 for length, 0.34 for total diameter, 0.22 for lumen diameter, and 0.37 for cell wall thickness. The genetic correlations among these traits were all greater than 0.69 except the correlation between length and lumen diameter which was 0.42. Measurement of tracheid length can be used to assess family differences for cell diameter and cell wall thickness.None of the tracheid traits were strongly correlated with average disk density or the disk density of rings 3-5. Therefore, genetic selection for high average density in 10 to 12 year-old loblolly pines from the provenances studied here will not produce a predictable pattern in the character of outer-ring latewood tracheids.

Abstract:

The non-native Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) has been grown to a limited extent in the southern part of Sweden since the early 1900s. A more extensive use has probably been curtailed by its known susceptibility to damage by frost, pine weevil and other pests. Limited access to vital seedlings of suitable provenances has also restricted its more widespread growth. The need for valuable species that will grow well through ongoing climate change has increased the interest for Douglas fir in Sweden. This thesis addresses a number of important questions relating to the planting of Douglas fir in Sweden: seedling storability, freezing tolerance, timing of bud burst, frost damage and seedling response to site preparation. Seven Douglas fir provenances originating from British Columbia, Canada were used in the experiments and where applicable, compared with a local provenance of Norway spruce (Picea abies (L.) Karst.). The early bud burst of interior Douglas fir provenances, observed both in greenhouse tests and in the field, results in a high risk of damage by late spring frost. This type of damage does not seem, however, to be fatal and does not obviously retard the early growth of seedlings. The difference in growth between coastal and interior provenances was insignificant, but survival was greater for interior than for coastal provenances. All the provenances of Douglas fir studied showed a later development of freezing tolerance of shoots and roots in the autumn than Norway spruce, with the coastal provenances developing such tolerance even later than interior provenances. This could be a contributory cause for the severe damage by winter desiccation observed on seedlings of coastal origin. A thorough site preparation proved to be an effective way to increase survival and root growth. Interior provenances of Douglas fir became ready for storage earlier in autumn than coastal provenances. When freezing tolerance of shoots had increased sufficiently, Douglas fir seedlings could safely be kept in frozen storage using the same procedures used for Norway spruce. The results emphasise the need to gain further knowledge about how the remaining obstacles to establishment of Douglas fir could be reduced with different silviculture methods.

A composição química de cortiça, floema e xilema foi determinada em árvores jovens de Quercus suber L. de três proveniências (Alcácer do Sal, Azeitão e Santiago do Cacém) de uma importante região de produção suberícola em Portugal, tendo em vista a análise de eventuais diferenças entre proveniências. Foram estudadas três árvores por proveniência, determinando-se o conteúdo em cinzas, extractivos (solubilizados em diclorometano, etanol e água), suberina (no caso da cortiça), lenhina e polissacáridos. Os três tecidos mostraram grandes diferenças na sua composição química. A composição química média da cortiça foi a seguinte: 0,66 % em cinzas, 11,7 % extractivos, 42,3 % suberina, 24,1 % lenhina e 16,2 % polissacáridos; do floema 2,9 % cinzas, 4,5 % extractivos, 38,0% lenhina e 49,1 % polissacáridos; e do xilema 1,1 % cinzas, 5,6 % extractivos, 23,4 % lenhina e 64,6 % polissacáridos. A análise estatística mostrou que a proveniência apenas foi um factor de variação significativo para os extractivos em etanol no caso da cortiça e os polissacáridos no floema. A composição monomérica da lenhina de todas as amostras foi analisada por pirólise analítica a 650 ºC. A lenhina dos três tecidos difere substancialmente: o rácio S/G foi 0,12 na cortiça, 1,1 no floema e 2,3 no xilema. Os compostos obtidos por pirólise foram também identificados e, sempre que foi possível determinar a sua origem, agrupados em açúcares, lenhina e suberina (apenas nas amostras de cortiça). Os açúcares representaram 58,6 %, 63,1 % e 25,4 %, a lenhina 14,4 %, 10,4 % e 12,6 % respectivamente no floema, xilema e cortiça, e a suberina na cortiça representou 33,0 % do total dos picos dos pirogramas

Abstract:

Increasing drought and salinity tolerances in economically important trees adapted to dry land areas is key challenge for maintaining the socioeconomic welfare of dry land areas. Strategies to improve drought and salt tolerance must examine the tree physiological mechanisms that link to the trees survival and growth. This study examined physiological adaptive traits allowing Senegalia senegal to grow better in both saline and dry lands. We conducted two greenhouse experiments and one field study to characterize growth, photosynthetic capacity, water use efficiency (WUE) and gum arabic yield potential among different Senegalia senegal provenances. In the first experiment, we tested early growth and photosynthetic response of seed sources to a cyclic drought treatment. The second greenhouse study examined seed source response to drought, salinity and fertility conditions. Gum yield assessment, growth and WUE of mature trees were determined from a field trial. In general, results showed a high intra genetic variability of Senegalia senegal on gum yield, biomass accumulation and growth. Ngane provenance presented superior growth characteristics as both mature trees and seedlings and exhibited a more conservative water use strategy under drought. Both greenhouse studies revealed similar photosynthetic capacity among Senegalia senegal genotypes when conditions are not limiting. However, when factors such as salinity, fertility and severe drought are involved, different physiological and morphological responses appear and at times this was dependent on seed source. But, at moderate drought stress (chapter 2), no drought by provenance interaction was found. Results of chapter 3 revealed that Ngane has larger stomata with low density in comparison with Diamenar and Kidira provenances. With the exception of Ng21B1, all seed sources displayed similar adaptations to salt stress in term of biomass accumulation. Fertilizer increased total biomass of all seed sources from 63% to 213% for Ng21B1 and K17B19, respectively. However, salinity reduced the fertilizer effect on biomass increment. Leaf gas exchanges were affected by salinity and fertilizer within various responses among seed sources. Results of chapter 4 revealed that gum yield was found to be positively correlated with tree height, crown width, stem volume index and crown area index. Ngane and Diamenar appeared the best provenances in term of annual gum yield per hectare. Diamenar had a higher survival rate than Ngane. This finding reveals the need to consider the tradeoff between tree survival rate and individual tree gum yield in Senegalia senegal stands. In addition to being more sensitive to salinity, Ngane also seems to be more susceptible to low soil pH in terms of survival, but this result needs to be tested further. This study suggests that improvement of gum arabic production can be possible through genetic selection. But, for the best adapted genotypes, research should explore new genetic combination and investigate physiology and genetic diversity. Moreover, the findings on the relationship between soil pH and tree survival rate suggests a need for care in selecting appropriate sites for Senegalia senegal stands. Therefore, silviculture practices as well as genetic selection appear critical in improving gum arabic production.

Abstract:

Forest tree species are very important in terms of carbon sequestration. Trees store 50% to 75% of the carbon they take up from the atmosphere in their wood, and the rest is released back into the atmosphere during respiration. Douglas fir is forest tree species native to North America, but shown successful growth and high productivity and quality in Europe. Douglas-fir is also considered as a species with high carbon sequestration, with the yearly average carbon storage of 46,46 kg CO2/year and for this reason it is increasingly popular as a tree for planting. This research aims to select the best provenances of Douglas fir for carbon sequestration in the provenance test in Bosnia and Herzegovina. Material for this research were Douglas fir trees in provenance test in Bosnia and Herzegovina, locality Batalovo brdo near Sarajevo. The provenance test was established in 1966. by planting 2+2-year-old seedlings, and included 5 provenances from Washington, Oregon and Canada, and from altitudes of 150-900 m above the sea. Heights and diameter at breast height of 52-year-old trees were measured, and volumes of trees were calculated. The results showed that the lowest average volume had provenance from the altitude of 900 m, 83-3.0 (0.7313 m3), and the highest provenance from 300 m, 65-1,0 (1.3410 m3). If there are 625 trees per ha, provenance 83-3,0 would produce 457 m3/ha, and provenance 65-1,0 838 m3/ha, which indicates differences in carbon sequestration. The obtained results can be used in selection of provenance for using in introduction of Douglas fir in Bosnia and Herzegovina.

Abstract:

Abstract This paper discusses the evolution of the configurations of a complex design artifact in a distributed concurrent engineering (CE) design environment. A generalized object-oriented model which captures the evolution of configurations and their components will be preseneted. We not only describe the object-oriented model, we also show how the dynamics between a configuration version and its components’ versions is maintained. The notions of version domain and version provenance are introduced to represent the domain-specific versions and to show how an object version arrives in its current state based on the 5W provenances (When, Who, Where, What and Why). A distributed architecture of a CE design environment will be also presented.
