    industrial pollution
    Opis:
    Environmental pollution greatly decreases a tree’s health and results in dieback of forest stands. Due to increasing industrial activity in the 20th century, silver fir became almost totally extinct in the Katowice Forest District. Only 19 individuals have survived to this day. The aim of the present study was to analyze growth characteristics and polymorphisms of 25 inter-simple sequence repeats (ISSR) of the preserved trees. The mean height of the inventoried silver firs was 19 m with a diameter at breast height (DBH) of 29 cm. Flowers were observed on few trees only. However, all trees were of high vitality without signs of fungal pathogen infections or insect outbreaks. Parameters of genetic variability, including mean effective number of alleles per locus and expected heterozygosity, were higher than described in the literature so far and they amounted to 1,659, 0,396 respectively.

    Opis:
    Paper presents an analysis of phenotypical variation and an evaluation of silvicultural quality of progeny from 27 beech stands around Poland that grow on the provenance plot in the Brzeziny Forest District (51.791997°N, 19.813841°E). The trial commenced in spring 1996, on the basis of 2−year−old saplings with covered root systems. A randomised block method with 3 replications was applied, with subsequent measurements and analyses carried out in 2015, following 20 years of growth. The considered features included height, breast−height diameter, crown habit, trunk curvature and height of branching. Single−factor analysis of variance and Tukey’s HSD test were applied to determine the significance of differences among provenances. The largest mean height was attained by beeches originating from Gdańsk, Szczecinek and Bierzwnik. The least−tall beeches were in turn those whose origins were in Tomaszów, Łagów and Grodzisk. The greatest intra−population variation in height characterised the beeches from Gryfino and Krucz, while the most limited variation was noted for Gdańsk population. The beeches of greatest girth were again those deriving from Gdańsk, Bierzwnik and Szczecinek populations, as well as the one from Kwidzyn 15. The lowest values for diameter at breast height were again noted for the Grodzisk, Tomaszów and Łagów provenances. Marked intra−population variation in this feature characterised trees from the Gryfino, Bieszczady National Park (42), Zdrojów and Krucz provenances. The populations also differered in relation to analysed more−qualitative features. The group of populations prized most in terms of their overall silvicultural quality included Gryfino, Grodzisk, Zdrojów, Bieszczady National Park, Bierzwnik and Szczecinek provenances. In contrast, only low quality was manifested by beeches from Tomaszów, Rymanów, Wejherowo, Młynary, Golub− −Dobrzyń and Kwidzyn provenances. In general, populations originating from the north (especially Pomerania) achieved better growth and a more favourable quality evaluation than those from the south, and sites located near the range limits of the species (fig. 7). The obtained results show that northern Poland boasts the most plastic populations of beech. Equally, it was not possible to establish that populations of local origin were superior in terms of growth to those originating in more far−flung parts of Poland. Furthermore, assessments of different populations in terms of their growth and quality features often proved highly disparate.

    Opis:
    The aim of the study was to determine the biomass and nitrogen accumulation in early maturing soybean plants experiencing contrasting weather conditions. Soybean (Glycine max) is a species of agricultural crop plant that is widely described in scientific publications. During 2014–2016, a field experiment with early maturing soybean ‘Merlin’ was carried out at Grodziec Śląski, Poland (49°48'01" N, 18°52'04" E). Results showed that the morphological traits of the plants, the yield of individual plants, and the soybean crop were all closely related to the climatic conditions. A high amount of precipitation stimulated seed development, resulting in a high production potential. The harvest index calculated for soybean ‘Merlin’ was high and exceeded 0.5 g g−1. The nitrogen content of the aboveground biomass increased during ontogenesis. The maximum yield of dry matter was noted at the green maturity phase, which subsequently decreased at the full maturity phase because of the loss of the leaf fraction. The variation in the effectiveness of nitrogen accumulation in seeds between 2015 and 2016 was 30%. The nitrogen harvest index values were high in each year of the experiment and exceeded 0.92 g−1. For the production of 1 ton of seeds with an adequate amount of soybean straw, plants needed, on average, 68 kg of nitrogen.
    Celem badań było określenie akumulacji biomasy i azotu we wcześnie dojrzewającej odmianie soi [Glycine max (L.) Merr.] w zmiennych warunkach pogodowych. W latach 2014–2016 w Grodźcu Śląskim (49°48'01" N, 18°52'04" E) przeprowadzono eksperyment polowy z wcześnie dojrzewającą odmianą soi ‘Merlin’. Wykazano, że cechy morfologiczne roślin soi oraz plonowanie były ściśle związane z warunkami klimatycznymi. Wysoka ilość opadów stymulowała rozwój nasion, dając w rezultacie wysoki potencjał produkcyjny. Indeks żniwny (HI) obliczony dla odmiany ‘Merlin’ był wysoki i przekraczał 0.5 g g−1. Zawartość azotu w nadziemnej biomasie wzrastała wraz z rozwojem generatywnym roślin. Maksymalną wydajność suchej masy odnotowano w początkowej fazie dojrzewania. W fazie pełnej dojrzałości wydajność suchej masy spadła, z powodu utraty frakcji liści. Zróżnicowanie w efektywności akumulacji azotu w nasionach w latach 2015–2016 wyniosło 30%. Wartości indeksu żniwnego azotu (NHI) były wysokie w każdym roku doświadczenia i przekraczały 0.92 g g−1. Do produkcji 1 tony nasion z odpowiednią ilością słomy rośliny potrzebowały średnio 68 kg azotu.

    Opis:
    The study objective was to verify the hypothesis on ecotypic variation in beech and ineffectiveness of transferring its reproductive material over larger distances. Beech nuts were collected in the autumn of 1990. Experimental sites were established in the Baligród and Oleszyce forest districts (SE Poland). On single plots of 18.00×13.75 m (247.5 m2), a total of 110 three−years−old seedlings were planted in a 1.50×1.25 m spacing in autumn 1993. Single row of mountain ash was left between the plots. In the period of 1994−2016 a series of analyses was conducted concerning adaptation, growth, phenological and qualitative traits. Height was measured on all trees using a measuring stick, except for the year 2016, when hypsometer was used to measure approximately 20 heights and remaining ones were determined based on the height curve. Results were analysed using univariate analysis of variance based on the random model, followed by Duncan’s multiple range test for each experimental site and year of the study. For 2016 ordering of populations in each of the experimental sites was compared using Spearman’s rank correlation test. In terms of survival rates in Oleszyce site the local provenance from Oleszyce proved to be superior. In all the years of the measurements it was characterised by the highest survival rate. In this respect the Komańcza and Lutowiska provenances from the Bieszczady Mountains turned out to be the worst ones. In the experimental site in Baligród, the Barlinek and Połczyn provenances outranked the others in terms of their survival rates, while in 2016 it was the population from Komańcza. Tree height effects in Oleszyce site showed that the local population from Oleszyce grows best, while the Pomeranian population from Jamy was also exceptional. The Bieszczady populations (Komańcza and Lutowiska) are characterised by the worst growth traits. In the experimental site in Baligród, the local Baligród population is characterised by poorest growth, similarly to the other ones from the Bieszczady. In terms of growth, the Western Pomeranian population from Gryfino is exceptional. As far as all the evaluated traits are concerned the investigated populations exhibit considerable variability, as no geographic ordination could be found. It was confirmed that imported populations, even from long distances, may exceed local populations in terms of their adaptation traits and growth rates.

    Opis:
    A total of one hundred and twenty ducklings (i. e. 60 Muscovy and 60 Mallard) were used for the study to evaluate the breeds effect on growth performance and prediction of body weight using linear body measurements of two breeds of ducks with the aid of General Linear Model and stepwise regression procedure of SPSS. Data on individual body weight (BW), body height (BH), body length (BL) breast circumference (BC), thigh length (TL), bill length (BIL), wing length (WL)and shank length (SL) of 120 ducks were collected on Muscovy and Mallard ducks and used to predict body weight at 4 and 8 weeks. The results showed that Muscovy (56.6t ± 6.7 – 1037.5 ± 30.29g) was significantly superior (P<0.05) to Mallard (51.8 ± 1.66 – 875.44 ± 70.30g) in body weight and in all the linear body measurements from day old to week 10. Individual body weight and linear body measurements was predicted at various ages (4 and 8 weeks) by genetic groups. The values of the coefficient of determination (R2) ranged from (88.6 – 97%) and (81.8 – 90.3%) in Muscovy and Mallard respectively at week 4. While, (R2) ranged from (58.7 – 92%) and 80.1 – 86.9%) in Muscovy and Mallard respectively at week 8. Since linear body measurements that can readily predict body weight without ducks being slaughtered, it is therefore, highly desirable as it will ensure the selection of animals that will reach market weight and size at relatively faster rate. This will also serve as a tool for breeders in selecting animals destined for use as breeding stock. These Muscovy and Mallard can be improved by exploiting the principle of phenotypic plasticity to obtain strains to complement other breeds of duck. Muscovy can also be used to upgrade some other indigenous ducks for better performance in a systematic breeding program.

    Opis:
    The growth rate and developmental traits of oak provenances were studied in spring 2001. The studies showed significant differences between provenances with regard to survival, tree height, dbh, basal area, volume, stem straightness, branch angle, epicormic shoot formation and foliage losses. There were no inter−population differences for stem forks, grade of natural stem pruning and bio−social position of trees in a stand. Provenances: Kórnik, Białowieża and Dębina exhibited the best height growth. Trees from the Białowieża provenance had the straightest stems with a few epicormic shoots. The performance of sessile oaks under the site conditions of the experiment was much poorer than of penduculate oaks. No geographical patterns were found for growth performance and developmental traits. The obtained results indicate the possibility to select provenances of fast−growing trees with economically advantageous traits.

    Opis:
    A wide range of soilless cultivation techniques have been developed and introduced for intensive cropping systems and for boosting the crop yield of many vegetables, mainly in greenhouses. Adoption of some local natural by-products to be utilized as a substrate growing medium to overcome soil-related problems appeared to be a promising project. Therefore, greenhouse experiments were conducted at the Baloza Experimental Station of the Desert Research Center (DRC), North Sinai Governorate, Egypt, during the two consecutive winter growing seasons of 2016–2017 and 2017–2018. These experiments aimed to investigate the effects of seven growing substrate culture treatments of separated or mixed sand obtained from sand dunes and date palm tree residues (Karenna) on plant vegetative growth, flowering, fruit yield and quality traits, and fruit nutritional values of cucumber plants (Cucumis sativus L.) Filial-1 hybrid 1101. Crop evapotranspiration reference (ETc) and water use efficiency (WUE), as well as treatment feasibility, were also studied. The experiment was set up in a complete randomized block design with three replicates. The obtained results strongly indicated that growing substrate media containing 25% sand (S) from sand dunes mixed with 75% grinded Karenna (Kg) of date palm (1 S + 3 Kg) significantly recorded the superiority of all studied characters of plant vegetative growth, number of flowers, fruit set, yield and its components, as well as fruit N, P and K contents, compared with other growing substrate medium treatments. On the contrary, the worst values of all studied parameters were achieved when sand was used alone (100% S) as a growing media. Furthermore, the highest water use efficiency and net income values were also attained by the 1 S + 3 Kg media treatment relative to the other growing substrate medium treatments.

The conducted studies showed a high (over 90%) survival rate of the tested fir provenances. The growth of the West Carpathian (Beskid Śląski, Beskid Żywiecki, and Beskid Mały) fir provenances was high on the majority of the KGB conservation plots, while the height growth of fir stands from the central part of the Carpathian Mountains (Beskid Wyspowy, Beskid Sądecki, and Beskid Niski) was on an average level. The East Carpathian (Pogórze, Słonne and Bieszczady Mountains) provenances were significantly diversified in terms of the height and did not form a homogenous group.

    Opis:
    European beech is one of the most important broadleaved tree species in Poland and will play probably even more significant role in the future due to the predicted climate change. The main objectives of this study was to analyse and compare the growth parameters and morphological traits between 23 European beech provenances from south−eastern Poland (fig. 1). The research was conducted on the experimental plot established in Łosie Forest District in 2006. The experiment employed a randomized complete block design consisting of 92 plots (23 provenances×4 blocks). On each plot 100 trees representing given provenance were planted in 1.5×1.5 m spacing. In the spring and autumn 2015 we measured and determined the following parameters for the subsample of 36 trees on each plot: survival rate, tree height, diameter at breast height, diameter of the branch at the middle height of the crown length, stem straightness, crown shape, tendency to create forks, mean angle between stem and branches and spring phenology. We also included different eco−physiographical characteristics for each provenances (tab. 1). We performed basic statistics to describe mean values and standard errors (fig. 2, tab. 2) and finally we quantified the interaction between traits and eco−physiographical characteristics by Principal Component Analysis (PCA) (fig 3, tab. 3). The obtained results indicates that under growth conditions on experimental trial in Łosie Forest District, the provenances from lower elevated regions with lower precipitation and higher mean temperature (i.e. more arid conditions; Kielce and Narol provenances) were characterized by thicker dbh and branch dimeters in contrast to regions from southern Poland (Łosie, Bricza 1, Stary Sącz and Nawojowa). European beech provenances from regions with more humid conditions and lower mean annual temperature, as well as shorter vegetation season are characterized by higher survival rate. They are also higher than other provenances, but reveal the lower ratio dbh to branch diameter.
