Opis:
The present study was aimed to find out whether the preformation of future shoot’s organs within a bud is reflected in the bud size/shoot functional traits’ size relationships. The survey attempts to evaluate whether relationships between the bud mass and stem mass, leaf mass, leaf area, total mass and number of leaves, respectively, of spring-shoot sprouted by the bud in Fagus sylvatica (L.) saplings are affected by parental bud location within shoot and parental shoot type. Dry mass of the terminal bud, the first and the last lateral buds placed on terminal and uppermost lateral shoots was estimated nondestructively for 58 beech saplings in December 2008. The shoots sprouted from the measured buds were sampled at the end of growing season, in August 2009. Bud mass, parental shoot type and bud location explained about 90% of shoot traits variability in full-factorial ANOVA. The leaf mass was the only shoot trait not affected by parental shoot type and bud location within shoot in scaling relationship with bud mass. There was not found differences among intercepts across parental shoot types and bud locations, however significant shift along common slope was observed among them. The presented findings could be viewed as a confirmation of the preformation and full development of leaf primordia within the European beech buds prior to bud burst.

Opis:
Saponaria officinalis L. is a medicinal plant from the family Caryophyllaceae. It occurs in most European countries, as well as in North Africa, America and Western Asia. The aim of the study was to find an optimal method of sterilization S. officinalis seeds in order to obtain sterile seedlings and to multiply axillary shoots from nodal explants isolated from them, on MS medium with the addition of growth regulators (RW). In this study, 4 variants of seed sterilization were compared using NaClO at the following concentrations: 1.5% (2), 2% (3) and 2.5% (4) for a period of 11 minutes. The control was a variant in which 70% C2H5OH was used for pre-sterilization for 1 minute (1). The highest percentage of sprouted, seeds and sterile seedlings and the lowest percentage of contamination were obtained in variant (4). As a result of micropropagation of soapwort in in vitro cultures, axillary shoots were formed from nodal explants from axillary buds. The highest percentage of explants with shoots (95%) and callus tissue (48%) and the highest number of shoots from one explant (5.95) were obtained in the second passage on MS medium with the addition of 4 mg.dm-3 BAP and 0.5 mg.dm-3 NAA. Due to the wide possibilities of using soapwort, it is advisable to continue research aimed at developing an optimal and efficient plant regeneration system of this species.

Opis:
The purpose of the study was to determine which fungal species colonize the shoots of apple, pear, cherry, plum, apricot and peach in south-eastern Poland and whether Diaporthe (Phomopsis) isolates there are among them. The study was conducted in 2010–2012 and the plant material was collected from five orchards. In three of these chemical controls were carried out, while there was no protection applied in the other two. The results showed that species composition of the fungi was very similar regardless of host plant and year of study. Alternaria spp., Fusarium spp. and Phoma spp. were isolated most frequently from the studied shoots. Fungi cultures known for pathogenicity towards fruit trees such as Botrytis cinerea, Colletotrichum gloeosporioides, Leucostoma spp., Monilinia spp. and Neofabraea spp. were also isolated. Moreover, there were isolates of Diaporthe (Phomopsis) among the fungi present in the shoots. Cultures of these fungi were obtained both from shoots with disease symptoms and from visually healthy ones but mainly from shoots originating from unprotected orchards, what indicates their greater threat to fruit trees grown without chemical protection. This is the first documented report of the occurrence of Diaporthe (Phomopsis) on fruit trees in Polish conditions.

Opis:
This work is a continuation of research on Diaporthe genus isolates obtained in 2010−2012 from fruit trees in Poland, which on the basis of previously conducted molecular tests, have been identified as one species belonging to the Diaporthe eres species complex. The aim of this study was to determine the morphology and pathogenic abilities of tested Diaporthe eres isolates. The experiment included cross tests, in which the shoots of apple, pear, cherry and plum trees were inoculated with each of the 4 isolates derived from each mentioned host plants. As a result of experiment, the pathogenic nature of D. eres in relation to the shoots of fruit trees, was confirmed. The isolates were also characterized on the basis of the colony appearance and spore dimensions. Morphological features of studied D. eres cultures were very similar, regardless of the isolate and the host plant, from which they were obtained. All tested isolates formed alpha and beta conidia having the same range size.

Opis:
The study shows the content of macro- and microelements in the leaves and rhizomes of Glyceria maxima of the Słupia River in Słupsk. The content of macro and micro-elements in G. maxima was analyzed for each component separately and in an integrated way, and comparing the demand for nutritions. The largest quantity of nitrogen, phosphorus, potassium, magnesium and calcium were found in the leaves, meanwhile zinc, iron, manganese, nickel and copper in the G. maxima rhizomes. The amount of Zn and Cu, in all of the tested positions, within the range of the limit for the plants, and the concentrations of Ni and Mn exceed physiological needs. The U Mann Whitney test showed a number of statistically significant differences in the concentration of the analyzed elements in leaves – rhizomes, leaves – bottom sediment and rhizome bottom sediment relation. The relations between designated heavy metals formed a following series: Mn>Fe>Zn>Ni>Cu in leaves and Fe>Mn>Zn>Ni>Cu in rhizomes. The G. maxima shoots accumulated 985.8 do 1441.4 mmolc∙kg-1 in all the analyzed components, and the lower value of the sum of the accumulated macro and microelements were found in rhizomes. The sum of ion comospition of the macronutrients in the leaves and rhizomes was similar. The content of nitrogen was 51.7–53.7% of this amount, 5.8–8.6% phosphorus, potassium 22.8 – 26.6%, 4.9-5.8% of magnesium, calcium, 8.2–11.9%, and trace elements were 0.58% in total, in the case of leaves and 8.70% in the rhizomes.

Opis:
The article examines the influence of physicochemical traits on yield depending on the variety and year of cultivation. Four common to Poland grape cultivars, i.e. ‘Regent’, ‘Rondo’, ‘Seyval Blanc’, and ‘Solaris’, were evaluated by analysing, among others, number of clusters per bush, their weight, number of berries, and the yield per hectare, number of woody shoots, weight of woody shoots, and the diameter of woody shoots. Energy and emission parameters were evaluated by conducting technical evaluation (lower heating value, ash content, volatile matters content, moisture content, fixed carbon) and elemental analysis (carbon, nitrogen, hydrogen, sulphur and oxygen contents) of one-year, two-year and three-year vine shoots. In addition, emission factors for CO, CO2 , NOx, SO2 and dust were estimated. The study showed that there was no significant differences between years under study (2020, 2021 and 2022) and energy and emission parameters. It was observed that the highest LHV (lower heating value) occurred in the ‘Regent’ cultivar while the lowest level in the ‘Rondo’ cultivar. As regards energy-emission parameters, a significant influence of cultivar (‘Solaris’, ‘Rondo’, ‘Seyval Blanc’ and ‘Regent’) was shown on the parameters studied except for nitrogen content and NOx emission index. The interaction of year and cultivar showed no significant differences except for the moisture content.

Opis:
The results of PCR examination indicated that during two years of tissue culture at standard conditions, on the medium with BAP 1 mg l-1 and continuous temperature of 20oC, phytoplasma could be detected in diseased plants of rose cv Sacha and Jazz. In the second year of micropropagation phytoplasma detection rate in tissues of infected roses increased and was relatively higher than in the first one. To test whether phytoplasmas are sensitive to temperature and light intensity, phytoplasma-affected micropropagated rose plants were grown on medium with BAP 1.0 or 0.5 mg l-1 and at the temperature of 4, 15, 20 or 25oC in darkness or in the light. PCR analysis indicated that phytoplasma detection was not effected by these conditions during 4 weeks of culturing. However, phytoplasma was not detectable in rose plants after 8 weeks culturing on the same medium without transplanting. Micropropagated rose shoots maintained on medium with Gentamycin or Baytril at the concentration of 25.0 or 50.0 mg l-1 had reduced growth and were chlorotic. However, no direct effect of applied antibiotics on phytoplasma detection was evidenced.

Opis:
In a pot experiment conducted in a greenhouse, the effect of CCC Bercema growth inhibitor to reduce vegetative shoot growth of perennial ryegrass and cocksfoot was studded. The experiment was set up in triplicate. Growth regulator was applied once, in a form of an aqueous solution. The following experimental objects were specified: control object, Bercema with a concentration of 10%, 20% and 30%. Ten measurements were performed every 3 days. The study was conducted under conditions of 12-hour artificial light daily. The results were statistically analyzed using two-factorial variance analysis . It was found that the greatest shoot growth reduction of ryegrass due to the highest inhibitor concentration (B- 30%), but for cocksfoot under the influence of the minimal concentration (B- 10%), compared to the control object. It has been noted that cocksfoot is more sensitive to the applied growth regulator, resulted in significantly greater inhibition of shoot regrowth than for ryegrass. In the experiment with the perennial ryegrass significant differences in the growth of shoots were found under the influence of inhibitor application at a concentration of 30%, compared to the control object. In the case of cocksfoot, all the concentration increases of Bercema inhibitor significantly differentiated the shoots regrowth.

Opis:
The frequency of occurrence of abnormal, three- (or more) needle dwarf shoots of most southern and central European two-needle pine (Pinus) species were studied. No specimens with more than two-needle dwarf shoots were found in a population of P. nigra Arnold subsp. salzmannii (Dunal) Franco from the Iberian Peninsula and in two populations of P. uliginosa Neumann from the Sudeten Mountains in Central Europe. Single specimens were found within one population of P. pinaster Aiton from the Iberian Peninsula and among six populations of P. sylvestris L. from the Iberian Peninsula and Central Europe. Abnormal dwarf shoots mostly with three, but also four, five or six needles were found among 24 of 25 surveyed populations of P. mugo Turra and P. uncinata Ramond. The average frequency of specimens with at least one three-needle dwarf shoot was 24% for P. mugo and 20% for P. uncinata. The frequencies of occurrence varied significantly among studied populations and were highest in samples collected from the upper elevational range limits of the species in the mountains and near the northern limits of their ranges. The frequency of abnormal dwarf shoots in the same populations was significantly high in 2-3 consecutive years. Needles from three-needle dwarf shoots were not significantly shorter than those of two-needle shoots.

Opis:
The aim of the study was to evaluate the contents of Cd, Pb, Zn and Cu in shoots of willow (Salix viminalis L.) cultivated in the vicinity of a coal ash and slag landfill. The landfill is surrounded by arable lands and meadows. There are two major negative influences of the landfill - dusting and flooding. The result of these interactions is the systematic reduction of agricultural value of the land. A field with an area of 9600 m2 were chosen. The land is located east to the landfill. A total of 40 samples of biomass was collected. The contents of analysed elements were determined by FAAS using a Unicam Solaar M6 spectrometer. Distance from the landfill affects the contents of Cd, Pb, Zn and Cu in the tested willow shoots. However, there is no single concentration pattern for all the investigated metals. An increase in willow cultivation on the described area can bring a good environmental effect and become an example of proper management of the ash and slag landfill neighbourhood.
