Daha çok Kafkasya ve Avrupa'da yayılış gösteren Epilobium alpestre, mevcut kayıtlara göre Türkiye’nin kuzeydoğusundan bilinen tek popülasyonla temsil edilmektedir. Bu çalışma ile taksonun Türkiye’deki dağılımı, ayrıntılı morfolojik özellikleri polen tohum mikromorfolojik verilerek türün sistematiğine katkı sağlanması amaçlanmıştır. E. montanum taksonu yakın benzerlik göstermekle birlikte vertis...
Thirty volunteer subjects were exposed to controlled amounts of respirable dust generated by the carding of cotton in an experimental cardroom. Eighteen exposures each lasting six hours were performed while carding unwashed and washed cottons from the three major growing regions of the United States. Elutriated dust was analysed gravimetrically and was comparable (0.59 mg/m3 +/- 0.04) for all e...
تحقیق حاضر عدد کروموزومی سلولهای غیر جنسی 7 گونه متعلق به 6 خانواده از ایران را گزارش میکند. عدد کروموزومی Epilobium palustre ;(36=n2) Geranium pyrenaicum ;(26=n2) Sium sisarum ;(20=n2) Veronica beccabunga (18=n2) برای اولین بار برای فلور ایران و Ferula persica (22=n2)؛ Tragopogon jesdianus (12=n2) برای اولین بار و گونه Bromusscoparius (2n=28) برای دومین بار از ایران گزارش می‌شوند و ایدیوگ...
The influence of various colors of soil cover (mulch) on the farred/red (FR/R) ratio in upwardly reflected light and on concentrations of chlorophyll (Chl) and light-harvesting Chl protein (LHC-II) were measured under field conditions. The FR/R ratios above green surfaces were higher than over white surfaces. Even though plants (Gossyplum hirsutum L. cv PD-1) were grown in full sunlight, those ...
مشاهدات کروموزومی برای 17 گونه متعلق به 9 خانواده ارائه شده است. شمارش کروموزومی برای 6 گونه شامل : Tanacetum polycephalum subsp. duderanum (Asteraceae) (n=18), Cardaria draba subsp. chalepensis (Brassicaceae) (n=32), Minuartia lineate (Caryophyllaceae) (n=10), Silene latifolia subsp. persica (Caryophyllaceae) (n=12+1B), Epilobium confusum (Onagraceae) (n=10), and Rumex scutatus (Polygonaceae) ...
In this study, pollen morphologies of eleven species the Epilobium L. genus belonging to Onagraceae family were investigated under light and scanning electron microscopy. Solutions taxonomic problems these sought with palynological information. The characteristics studied as a result studies are follows: grains It has been determined that their have tetrad, angulaperturate, 3-zonoporate (rarely...
