Opis:
The cowslip plants (Primula veris L.) in two natural populations in Wielkopolska set fruits in 80% on plants with one generative shoot. Mean number of fruits by a rosette varied from 4.7–9.0. In both populations the mean number of fruits by a scape and the value of a real seed production by a single capsule was higher for rosettes with one scape than for plants with two generative shoots.

Opis:
The evaluation of the viability and germination capacity of Lysimachia vulgaris L. seeds under garden cultivation conditions was done and the study on different number of leaves in whorls on shoots of L. vulgaris was performed. Germination capacity of the examined seeds ranged from 2.8% to 52.6% and differed significantly in dependence of the sowing time, germination conditions and the fact whether or not the seeds underwent the stage of vernalization. L. vulgaris plants with different number of leaves in whorls propagated generatively and vegetatively did not have the same number of leaves on their offspring. Plants with two leaves in whorls were most numerable (60.0-70.0%), three laves in whorls were observed on approx. 30.0% and four leaves on approx. 13.0% of the offspring.

Opis:
Occurrence requirements and spatial organisation of cowslip (Primula veris L.) natural populations from the Wielkopolska region were examined. On three chosen localities of P. veris the permanent plots were established in 1996 and 1997. The chemical analyses of the soil samples were made and the participation of different species in the examined populations was determined. On the basis of cartographic documentation and the value of the dispersion coefficient, the type of the spatial structure was determined.

Opis:
Genetic variation of twelve Polish populations of Primula veris L. from western Poland was investigated in respect of six enzyme systems: 6-phosphogluconate dehydrogenase (6PGD), diaphorase (DIA), menadione reductase (MNR), formate dehydrogenase (FDH), isocitrate dehydrogenase (IDH) and glutamate oxaloacetate transaminase (GOT). Only two of them (6PGD and DIA) were polymorphic and all populations were compared according to four loci and eight alleles. For 6PGD only one out of the two detected loci (locus 6PGD-2) was polymorphic and consisted of three alleles a, b and c. For DIA each of two detected loci had two alleles. For 6PGD-2 one population was monomorphic and four populations were monomorphic for DIA-1 and DIA-2. The rest of the populations were polymorphic with low frequency of heterozygotes. The low heterozygosity level, found in the examined populations, was confirmed by high values of the fixation index (F). The level of genetic differentiation among GST populations specified for each polymorphic loci, was equal to 0.045 for 6PGD-2 and had the value of 0.078 for DIA-2 and 0.186 for DIA-1. Nm value for polymorphic loci was 1.10 for DIA-1 and 2.94 for DIA-2, and for 6PGD-2 was 5.33, what indicates some gene flow between the examined populations. The dendrogram constructed on the basis of genotype frequencies showed that the populations were divided into two groups, however the most southern population No. 2 was clearly similar to the northern population No. 8.

Opis:
The cowslip plants (Primula veris L.) in three natural populations in Wielkopolska flowered on 37.03% to 75.00% of individuals. In all the examined populations most of the cowslip plants had only one generative shoot. The mutual proportion of individuals with pin and thrum flowers was different. The fructifying intensity was rather low, and the real seed production (RSP) varied from 35.80 to 43.81 seeds in one capsule.

Opis:
Introduction: Angelica archangelica L. (Apiaceae) has a long history of use as a vegetable and medicinal plant. According to the European Pharmacopoeia, the angelica root (Angelica radix) of only one of the subspecies – Angelica archangelica subsp. archangelica (formerly known as Archangelica officinalis) – is used as a source of plant material with documented medicinal properties. Within this species, there are two subspecies that are difficult to classify unambiguously: subsp. archangelica and subsp. litoralis. Objective: The aim of this study was to provide a micromorphological and anatomical description of fruits of A. archangelica and identify new diagnostic characters useful in subspecies identification. Methods: A comparative analysis of the sculpture and internal structure of fruits of the distinguished A. archangelica taxa was conducted, using scanning electron microscopy (SEM). Results: Based on the taxonomic characters in the Apiaceae family, micromorphological and anatomical characteristics of A. archangelica fruits were prepared. Some of the investigated characters, e.g. verrucose sculpture of the oil duct surface and the presence of hooked hairs, exhibited intraspecific differences. Among the anatomical characters, the variation was related to the number and size of the paraendocarpic oil ducts as well as to the thickness of dorsal and commissural mesocarp. Conclusion: SEM examination of fruits of A. archangelica provided a detailed description of their sculptures and several micromorphological and anatomical characters of potential diagnostic value.

Opis:
Results of anatomical studies on the developing endocarps of Cornus mas and C. officinalis are presented. Formation of an endocarp and anatomical changes in its structure from the flowering stage to fully developed fruits were observed with the use of LM and SEM. In the process of anatomical development of endocarps the formation of two layers, i.e. the inner and the outer endocarp, was observed. Changes in their anatomical structure consisted in a gradual thickening of cell walls and their lignification. The lignification of endocarp cell walls begins in the inner endocarp, it proceeds in the outside parts of the outer endocarp, with an exception of several layers of cells forming the transition zone (circular strand) present on its margin, and finally, almost at the same time, in the rest of the outer endocarp. Cell walls of the cells distinguishing the germinating valves undergo thickening delayed by several days in comparison to other endocarp cells. Thickening of their cell walls starts in cells situated close to the inner endocarp and proceeds to its outer parts, and their lignification is not very intensive. The described scheme of the development and lignification of C. mas and C. officinalis endocarps is similar to that of Prunus cerasus (Rosaceae).

Opis:
Micromorphological characterisation and the comparative statistical analysis of the size of Primula veris L. pollen grains collected in three natural and three cultivated populations were done. Observations were carried out with SEM. The obtained measurements were analysed with the use of one-way ANOVA, Kruskal-Wallis Test and the Student-t Test. Pollen grains from long-styled ('pin') flower-morphs were mainly 6 colpate and from shortstyled ('thrum') flower-morphs 8 colpate. Colpi of some grains from 'thrum' flowers were 'sinuous' and 'circular', and they incised into the apocolpium zone. Ornamentation of 'pin' pollen grains was microreticulate, with lumina up to 0.8 μm wide, and for pollen grains from 'thrum' flowers was reticulate and eureticulate with lumina 1.1-1.7 μm wide. In lumina of mesocolpium area some free columellae were observed. Pollen grains from 'thrum' flower-morphs were more variable in size, both in natural and in cultivated populations, than grains from 'pin' flower-morphs. The differences in mean length (P) and breadth (E) of pollen grains from 'thrum' flowers collected in cultivated populations were statistically important (FP = 3.154 for the critical F005 = 3.098; K-We = 7.469 for the critical Test value α=005 = 5.991). Pollen grains from 'thrum' flowers were bigger when coming from plants growing in natural populations (tE = 2.784 for the critical Test value α=005 = 2.001).

Opis:
Cornus mas L., C. officinalis Sieb. et Zucc. and their putative interspecific hybrid specimens were examined in order to describe their morphological, anatomical and genetic differentiation. Petiole length, number of leaf veins, pedicel and bract length, stone size, thickness of pericarp layers, the size and number of locules and the number of cavities were measured. Pedicels and bracts were shown to be significantly longer for C. mas (7.22 and 6.95 mm) and for the putative hybrid (9.11 and 6.61 mm) than for C. officinalis (6.86 and 5.81 mm, respectively). Average values of stone width and thickness, exocarp and mesocarp thickness, the number of cavities in the endocarp obtained for the putative hybrid differed significantly in comparison to C. mas and were similar to C. officinalis. Genotypes of the examined species were evaluated for genetic relationships using random amplified polymorphic DNA (RAPD) markers. Initial screening of the bulks of C. mas and C. officinalis compared with their putative hybrid using 72 decamer random primers resulted in the identification of 24 primers differentiating both species and their putative hybrid and showing reliable polymorphisms. Among a total of 485 amplified fragments, 89.7% were polymorphic, 18.8% were specific to C. mas individuals, and 18.6% were specific to the individuals of C. officinalis. In obtained profiles of the examined hybrid individual specific products absent in the genotypes of both parents were observed. The phylogenetic tree revealed two separate clusters including C. mas and C. officinalis accessions, respectively. The biggest genetic distance was observed for hybrid specimens, although the hybrid belonged to the C. mas cluster.
