The present paper gives the chromosome numbers of 27 species belonging to Angiosperms. Most of chromosome numbers established in Polish material was previously known for plants from other geographical regions or from Botanical Gardens. A new report is the presence of accessory chromosome in diploid set of Allium angulosum L.

The paper reports chromosome numbers for 13 taxa of Elatine L., including all 11 species occurring in Europe, namely E. alsinastrum, E. ambigua, E. brachysperma, E. brochonii, E. californica, E. campylosperma, E. gussonei, E. hexandra, E. hungarica, E. hydropiper, E. macropoda, E. orthosperma, E. triandra originating from 17, field-collected populations. For seven of them (E. ambigua, E. californica, E. campylosperma, E. brachysperma, E. brochonii, E. hungarica, E. orthosperma) the chromosome numbers are reported for the first time. With these records, chromosome numbers for the whole section Elatinella Seub. became available. Although 2n = 36 was reported to be the most common and the lowest chromosome number in the genus, our data show that out of thirteen species analyzed, six had 36 chromosomes but five species had 54 chromosomes, and the lowest number of chromosomes was 18. These data further corroborates that the basic chromosome number in Elatine is x = 9.

We used chromosome data to verify the taxonomic affiliation of specimens previously recognized as Brachyactis ciliata. All analyzed plants were diploids based on x = 7 (2n = 2x = 14), the basic number characteristic for Symphyotrichum ciliatum, allowing the examined species to be shifted from the genus Brachyactis to the genus Symphyotrichum sect. Conyzopsis. The chromosome number (2n = 2x = 14) for specimens of S. ciliatum from Poland is reported for the first time.

Solanum genus namely Solanum seaforthianum Andr. belongs to the Solanaceae family, and comprises only dioeciously species. These plants are distributed between 29º and 40º south. All species of this genus are diploid with chromosome numbers of 2n = 24, 28 and 30. According to literature, the basic chromosome number in this genus is x = 12, 14 and 15. Solanum genus with a chromosome complement of 2n = 30 has a symmetric karyotype with a median and sub median centromere position. Because ancestral species have a symmetric karyotype, it seems that x = 12 is the initial basic chromosome number in this genus and the x = 14 and x = 15 derived from x = 12. So it seems that diploid phenomena played an important role in evolution and speciation.

Hieracium zajacii Szeląg is described from the Vel'ká Fatra Mts in Slovakia. It is the first representative of H. lycopifolium agg. to be found in the Carpathians. The new species is tetraploid (2n = 36) and reproduces apomictically. Its origin is briefly discussed.

Callus was successfully induced from the mature endosperm of three Actinidia species: A. arguta, A. deliciosa var. deliciosa (kiwifruit) and A. kolomikta. For the initiation of callus, MS medium supplemented with 2,4-D (2 or 4 mg/l) and kinetin (5 mg/l) was used. Transfer of the callus to medium containing IAA (0.1 mg/l) and BAP (1 mg/l) resulted in the formation of roots in approximately 40% of the endosperm explants of A. deliciosa. The callus, initially yellow-white, turned green when cultured in the light. In A. arguta and A. kolomikta no morphogenic response was observed on this medium. If the cultures were inoculated onto medium with IAA (0.3 mg/l) and 2iP (5 mg/l), in the endosperm calluses of kiwifruit, shoots were formed in addition to roots. In A. arguta a few abnormal shoots were produced in one explant. The sub-culture of A. arguta callus on MS without hormone evoked the production of some roots. No morphogenic response was observed in the endosperm cultures of A. kolomikta on all media tested. The counting of chromosomes in five roots and young leaves of one shoot of A. deliciosa revealed that they were triploids with chromosome number 2n = ~250.
