    Opis:
    Anagallis arvensis L. fruits are globose pyxides. They contain a unique globose columella with 20-30 seeds on its surface. In ripe, open fruits the ball-shaped columella detaches easily and becomes a unique diaspore, which can roll on the ground. This way of dissemination has not been described so far neither in Anagallis nor in other Primulaceae.

    Opis:
    The work presents the results from the studies on the morphological and anatomical differentiation of Primula veris seeds from the natural localities and from the cultivation. On the basis of the biometrical analysis the very little inter-population variability and no distinct seasonal variability was stated. The increase of the seed’s size, the endosperm’s thickness and the embryo’s breadth in seeds from the cultivated plants was observed.

    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:
    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:
    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.

    The paper describes a newly discovered locality of the halophyte Samolus valerandi in the Wielkopolska Lowland. This is the third locality of this species in the Wielkopolska region. It was found on halophilic meadows in the planned nature reserve “Łaki Pyzdrskie” in the Nadwarciański Landscape Park.
