20.500.12556/DKUM-42359 Anatomija lista in listnega peclja grahovcev (Astragalus, Fabaceae) iz sekcije Incani v Evropi Leaf anatomy and anatomy of leaf petiole of Astragals, Fabaceae sect. Incani in Europe Namen diplomske naloge je bil poiskati razlike in podobnosti v anatomski zgradbi prečnih prerezov listov in pecljev obravnavanih taksonov, in sicer: Astragalus monspessulanus subsp. illyricus Bernh. (Slovenija, Kuteževo), Astragalus monspessulanus subsp. illyricus Bernh (Hrvaška), Astragalus monspessulanus subsp. illyricus Bernh. (Slovenija, Hrastovlje), Astragalus monspessulanus subsp. monspessulanus (Italija), Astragalus monspessulanus subsp. gypsophilus (Španija), Astragalus incanus subsp. incanus (Španija), Astragalus incanus subsp. nummularioides (Španija), Astragalus spruneri (Makedonija). Podrobneje smo obravnavali razlike med populacijami ilirskega grahovca (Astragalus monspessulanus subsp. illyricus Bernh.) v Sloveniji. Izdelali smo mikroskopske preparate svežega in herbarijskega materiala. Pri listnem peclju smo obravnavali naslednje parametre: hrbtno trebušno os, trebušno os, stranski žilni snop na trebušni strani, hrbtno sredinski žilni snop, premer skorje, ksilema, floema ter število spremljevalnih žil. Pri listu pa debelino zgornje in spodnje povrhnjice, premer palisadnega in gobastega tkiva, premer lista na področju žile ter širino lista. Mikroskopske preparate smo premerili v programu Image J, katerega avtor je Wayne Rasband in je brezplačno dostopen na internetu. Statistično smo jih obdelali z računalniškimi programi Excel (Microsoft Office Excel 2007) in Statistica (StatSoft, Tulsa, Oklahoma, ZDA). The purpose of this diploma work was to find similarities and differences in anatomical features of leaves and leaf petioles between discussed taxons: Astragalus monspessulanus subsp. illyricus Bernh. (Slovenia), Astragalus monspessulanus subsp. illyricus Bernh. (Croatia), Astragalus monspessulanus subsp. illyricus Bernh. (Slovenia), Astragalus monspessulanus (Italy), Astragalus monspessulanus subsp. gypsophilus (Spain), Astragalus incanus subsp. incanus (Spain), Astragalus incanus subsp. nummularioides (Spain), Astragalus spruneri (Macedonia). More specifically, we discussed the differences between the Illyrian populations of Astragalus (Astragalus monspessulanus subsp. illyricus Bernh.) in Slovenia. We studied the anatomy of the petiole and leaves by observing hand-made cross-sections. The analyze material consisted of fresh material and herbarium specimens. Concerning the leaf petiole, we discussed the following parameters: dorsal ventral axis, ventral axis, ventral lateral vascular bundle, dorsal median vascular bundle, diameter of the cortex, xylem, phloem, and the number of accompanying vessels. For the leaf blade, we discussed the thickness of the upper and lower epidermis, width of palisade layer and spongy tissue, blade diameter of blood vessels and the total width of the leaf blade. We measured anatomical structures with the help of Image J, a freely available software authored by Wayne Rasband, and statistically analyzed results with Microsoft Office Excel (2007, Microsoft) and Statistica 10 (2010, StatSoft, Oklahoma, USA). takson Astragalus anatomija listni pecelj list zgornja in spodnja povrhnjica palisadno tkivo gobasto tkivo hrbtno trebušna os trebušna os stranski žilni snop na trebušni strani hrbtno sredinski žilni snop spremljevalne žile stržen ksilem floem skorja. taxon Astragalus anatomy leaf leaf petiole the upper and lower epidermis palisade layer spongy tissue dorsal ventral axis ventral axis ventral lateral vascular bundle dorsal median vascular bundle accompanying veins central core xylem phloem cortex. true true false [T.
