چکیده

بررسی فلوریستیکی منطقۀ پُدُل، لِمَزان و کوه بِدو (90 کیلومتری شرق بندرلنگه، استان هرمزگان) با مساحت حدود 45000 هکتار، ارتفاع 1150 متر از سطح دریا در بلندترین نقطه و متوسط بارندگی سالانه 7/133 میلی‌متر هدف اصلی پژوهش حاضر است. نمونه‌های گیاهی، جمع‌آوری و با روش‌های تاکسونومیک شناسایی شدند. همچنین، فهرست گونه‌های گیاهی، شکل ‌رویشی، پراکنش ‌جغرافیایی و ارزش ‌دارویی آنها ارائه شد. در مجموع، 156 گونه متعلق به 130 سرده و 43 تیره در منطقه شناسایی شدند. Asteraceae، Fabaceae، Lamiaceae، Chenopodiaceae، Brassicaceae و Poaceae به‌ترتیب با 23، 16، 10، 9، 8 و 8 گونه بزرگ‌ترین تیره‌ها و Salvia، Heliotropium، Plantago، Astragalus و Capparis به‌ترتیب با 5، 4، 4، 4 و 3 گونه بزرگ‌ترین سرده‌ها در فلور منطقه هستند. طیف‌زیستی گیاهان منطقه شامل 1/39 درصد تروفیت، 36/24 درصد کامفیت، 44/22 درصد همی‌کریپتوفیت، 18/12 درصد فانروفیت و 92/1 درصد کریپتوفیت است که شرایط اقلیمی سخت منطقه را نشان می‌دهد. همچنین 89/35 درصد گونه‌ها منشأ ایرانی - تورانی و صحرا - سندی و 77/30 درصد منشأ صحرا - سندی دارند. تعداد 12 گونه (7/7 درصد) بوم‌زاد و 64 گونه (41 درصد) دارویی از این منطقه گزارش می‌شود که اهمیت فلور و پوشش گیاهی منطقه را نشان می‌دهند.

Abstract
Floristic survey of Podol, Lemazan, Bedoo mountain (located in 90 km eastern of Bandar Lengheh, Hormozgan province), with about 45000 hectars area and maximum elevation of 1150 meters above the sea level, and 133.7 milimeter annual precipitation, was the main goal of the present work. The collected specimens were identified using taxonomic methods. List of plant species, life forms, chorotypes and their medicinal values were presented. The results showed that 156 plant species belonging to 130 genera and 43 families of vascular plants grow in the area. Asteraceae, Fabaceae, Lamiaceae, Chenopodiaceae and Brassicaceae with 23, 16, 10, 9 and 8 species are the largest families, and Salvia, Astragalus, Heliotropium and Plantago with 5, 4, 4, 4 and 3 species are the largest genera in the region, respectively. The life forms frequency were 39.1% Therophytes, 24.36% Chamaephytes, 22.44% Hemicryptophytes, 12.18% Phanerophytes and 1.92% Cryptophytes, indicating the sever climate conditions in the region. Also, 35.89% of species are Saharo-Syndian and Irano-Turanian, 30.77% are Saharo-Syndian. Furthermore, 12 endemic species and 64 medicinal species are inhabitate in this region, indicating the importance of flora and vegetation of the studies area.
