    Opis:
    In recent years extensive attention has been given to the Rubus genus, but knowledge on the ecology of most of its species, including rhythmic development, is still insuffi cient. Such data may have practical applications, since blackberry species are economically important. The goal of the study was to analyse phenology and growth rate of vegetative and generative stems in 10 Rubus species of different systematic affi nity (belonging to two subspecies and three sections), growing in the Dendrological Garden of the Poznań University of Life Sciences. Some habitat factors were also taken into consideration. Field investigations were carried out for three growing seasons. The plants were evaluated for phenology twice a week, while the length of their stems was measured once a week. Diff erences were observed in the seasonal rhythm of individual species. Weather factors distinctly infl uenced the course of development phases in all the Rubus species. Drought during the growing season caused fl owering disorders, withering of fruit, earlier autumn leaf coloration, and fall of leaves. Rubus idaeus and R. fabrimontanus ripened all of their fruits each year of observations and seemed to be the most adapted for fruit production. Rubus fabrimontanus, R. kuleszae and R. praecox were the most vigorous species with reference to shoot growth. This study revealed that only some species were fully acclimated to the conditions of the Dendrological Garden, since they successfully completed their entire fl owering and fruiting cycles.

    Opis:
    The object of the work was population of spiny restharrow (Ononis spinosa) growing within the previous ecological site “Kopanina I” in the south-western part of Poznań. In total 67 specimens were found on the area of 825 m2. About half of them were in phase of flowering. Most of plants grew in clusters. They were a component of the meadow plant community of Molinio-Arrhenatheretea class with different degree of humidity. Together, there were 50 species of vascular plants, including two protected species. Analysis of ecological indicatory numbers revealed predominance of species connected with mineral-humus, mesoand eurotrophic, neutral or alkaine soils.

    Opis:
    During the last 10 years (2005–2014) the population of Epipactis palustris within the former ecological use “Kopanina 1” was observed five times. In subsequent years, on the area of 4400 m2 at least 1000 to more than 4000 ramets were noted. The ramets in generative phase of development always predominated. It might indicate good condition of the population. The highest density per unit of area was observed in the first year of the study. The length of stems and number of leaves were the most constant features in orchid population. Then the width of the bract was characterized by the greatest values of the coefficient of variation. During the entire study period the number of ramets in population of E. palustris fluctuated, mainly resulting from the biology of the species, and only substantially from the impact of weather conditions. Negative impact of diverse human activities and excessive expansion of the other plant species, which resulted in the shading of the orchid sites, are the major threats to E. palustris existence in the described object.

    Opis:
    Celem pracy było zbadanie zmienności pyłku u czterech typów odmian lnu zwyczajnego. Zmierzono długość osi biegunowej i równikowej ziaren pyłku oraz określono ich kształt. Największe ziarna miała odmiana oleista, a najmniejsze – odmiany włókniste. Wartości współczynników zmienności cech były niskie. Analiza wariancji wykazała, że odmiany różniły się istotnie pod względem badanych cech. Cechy korelowały ze sobą istotnie. Najbardziej podobne były odmiany włókniste oraz jedna z odmian oleistych i pośrednia. Odrębną grupę stanowiły dwie odmiany oleiste i ozdobna. Ziarna pyłku były symetryczne, wielkości średniej, wydłużono-kuliste, z trzema bruzdami w płasz-czyźnie równikowej, o częściowo wykształconym daszku. Nie stwierdzono istotnych różnic w mikro-morfologii ziaren pyłku analizowanych 11 odmian.
    The aim of this work was to investigate the variability of pollen morphology of four types of cultivars of common flax: oily, fibrous, intermediate and ornamental. In total, 11 cultivars were investigated. The biometry was performed for 30 pollen grains of each cultivar. Polar (P) and equatorial (E) axes were measured and on the basis of P/E ratio pollen shape was determined. Multivariate statistical analyses were carried out. The details of pollen morphology were studied with light and scanning electron microscopes. The largest pollen grains were found in oily cultivar. The smallest grains, with a high P/E ratio, were observed in fibrous types. Generally, the values of variation coefficients of analyzed traits were relatively low, whereas the lowest values were observed for oily cultivars and the largest ones – for fibrous and intermediate cultivars. Correlations based on cultivar averages were significantly different from zero for the length of the equatorial axis (E) and P/E ratio. In discriminant analysis, correlation between the measured characteristics and canonical variables showed that the first canonical variable was mostly of the correlated to the length of axis E and the second canonical variable to the relationship between both examined axes. The first canonical variable described reached up to 71.91% of the total variation, and the second variable – 20.43%. In total, the first two canonical variables explained 92.34% of the variation. Cluster analysis showed that the fibrous, oily and intermediate cultivars were similar. To each other to the largest extent. One factor analysis of variance the ANOVA (F-values) showed that the investigated traits differentiated all flax cultivars to a high degree. The length of the equatorial axis varied to the largest extent. All investigated pollen characters were significantly correlated with each other. The principal component analysis for 11 flax cultivars proved that PC1 explained 71.91% of the observed variability, whereas PC2 – 20.43%. Three major groups of grains were determined. Pollen grains were of large size, prolate-spheroidal in shape, with circular amb, trizonocolpate, semitectate, with LM gemmate sculpture visible, with SEM fossulate type of ornamentation. No significant differences were noted in pollen micromorphology among investigated flax cultivars.

    Opis:
    The research was carried out within three forest-park complexes located in the south-western part of the Poznań city, which once had the status of ecological uses. The aim of the work was to inventory a dendroflora for the selection of trees with monumental dimensions. In addition, changes in the participation of monumental trees in local vegetation over the last 12 years had been analysed. During the current inventory, 58 monumental specimens were recorded in three afforestation complexes. Most of them grew at Leszczyńska street (31 specimens), and the least at Tyniecka street (6). Since 2004 tree trunk perimeters had increased on average of 18.5 cm. All activities, including conservation works, undertaken in the three described afforestation complexes, or in the immediate vicinity, should lead to the preservation of these objects, their protection against devastation and to expose their most valuable fragments.

    Opis:
    Leaves from generative and vegetative shoots of Rubus capitulatus and R. kuleszae of Corylifolii section were investigated. The study was to demonstrate the variability of leaves of both types of shoots, and at the same time an examination on the contents of polyphenols and phenolic acids in their blades carried out. Selected blade traits, such as was: length, width, elongation, perimeter, dissection index, area, rectangularity and circularity were measured using computer program and statistically analysed. Additionally, fresh and dry leaves were weighed and the percentage of preserved mass of particular samples was calculated. A statistical analysis revealed the area to be the most variable feature in both species and both types of shoots. Leaves from vegetative shoots were the most similar to each other and the length, width, perimeter and area were the most strongly correlated traits to each other. The leaves of generative shoots of both species contained less water than the leaves of vegetative ones.
