Karyological review of pinopsida on the base the database
A review on karyology of modern conifers with the use of database «Chromosomе numbers of gymnosperms» is done. At pre-sent the database includes information on 1036 species, 85 genera, 15 families, 10 orders and 4 classes of gymnosperms. Information on all known numbers of chromosomes and bibliography is presented for each taxon. It is found that the number of chromosomes of gymnosperms is unknown for half of species and 40 % of species of conifers is not studied karyologically. The brief information on the features of chromosome morphology of conifers is given. It is revealed that the morphology of chromosomes is known in 30 % species only. Information about all, meetings chromosomal anomalies, and also lists of species which have these anomalies are re-sulted.
