| Seeds from nineteen native plant species belonging to 6 families (Apocynaceae, Capparaceae, Cleomaceae, Fabaceae, Resedaceae, and Zygophyllaceae) were collected in Bushehr Province, Iran. Chromosome counts revealed the following diploid numbers for all studied species, representing first records for the flora of Iran: Caralluma edulis (2n=22), Pergularia tomentosa (2n=22), Capparis cartilaginea (2n=20), C. parviflora (2n=20), C. spinosa (2n=20), Cleome glaucescens (2n=20), C. oxypetala (2n=20), Astragalus annularis (2n=16), A. boeticus (2n=16), A. hamosus (2n=16), A. meridionalis (2n=16), Ochradenus aucheri (2n=24), Oligomeris linifolia (2n=16), Reseda alba subsp. alba (2n=24), R. alba subsp. decursiva (2n=24), R. arabica (2n=12), R. aucheri subsp. bracteata (2n=24), Zygophyllum qatarense (2n=20) and Tribulus terrestris var. inermis (2n=24). Notably, three species in our samples (Capparis spinosa, Reseda alba subsp. decursiva, and R. aucheri subsp. bracteata) were found to be diploid (2n=20, 2n=24, and 2n=24, respectively), in contrast to previous reports that identified them as tetraploids (2n=4x=40 and 2n=4x=48). | ||

| چکیده [English] | ||
| در این پژوهش، بذور ۱9 گونه گیاهی بومی متعلق به ۶ تیره Apocynaceae ، Capparaceae، Cleomaceae، Fabaceae، Resedaceae و Zygophyllaceae، از استان بوشهر جمعآوری شد. شمارش کروموزومی 19 گونه شاملCaralluma edulis (Edgew.) Benth. ex Hook.f. (2n=22)، Pergularia tomentosa L. (2n=22)،Capparis cartilaginea Decne. (2n=20)، (2n=20) C. parviflora Boiss.،C. spinosa L. (2n=20)، Cleome glaucescens DC. (2n=20)،Boiss. C. oxypetala (2n=20)، Astragalus annularis Forssk. (2n=16)،(2n=16) A. boeticus L.،A. hamosus L. (2n=16)، A. meridionalis Bunge. (2n=16)،(2n=24) Ochradenus aucheri Boiss. ،Oligomeris linifolia (Vahl) Macbr. (2n=16)، Reseda alba subsp. alba (2n=24)،R. alba subsp. decursiva (Forssk.) Maire (2n=24)، R. arabica Boiss. (2n=12)، R. aucheri subsp. bracteate Boiss. (2n=24)، Zygophyllum qatarense (Hadidi) Beier & Thulin ،(2n=20) وTribulus terrestris var. inermis Boiss.(2n=24)، برای اولین بار در فلور ایران گزارش می گردند. نکته قابل توجه این مطالعه، مشاهده حالت دیپلوئید در سه گونه Capparis spinosa،Reseda alba subsp. decursiva و R. aucheri subsp. bracteata است که در مطالعات پیشین به صورت تتراپلوئید به ترتیب(2n=4x=40)، (2n=4x=48) و (2n=4x=48) گزارش شده است. | ||
