抄録

Male meiosis in 12 accessions belonging to 2 species of the genus Salvadora viz. S. persica and S. oleoides, an important medicinal and oil-yielding tree has been studied in detail. The somatic chromosome number in both the species is confirmed as 2n=24. Two basic numbers n=12 and 13 are contemplated for the genus. Analysis of chromosome associations revealed regular occurrence of univalents and bivalents. Among bivalents ring type were more in number as compared to rod bivalents, which normally had terminalized chiasma. A single nucleous which always showed affinity towards 1 to 3 bivalents, was the common observation in PMCs. Structural rather than numerical changes (polyploidy) seems to have played a significant role in speciation and evolution of the genus Salvadora.
