20.500.12556/RUL-188426 Vpliv prisotnosti gliv na anatomijo lesa trte The influence of the presence of fungi infectoin on wood anatomy of grapevine V raziskavi smo analizirali anatomske spremembe lesa vinske trte (Vitis vinifera), povezane s prisotnostjo gliv, s poudarkom na primerjavi med prizadetimi in kontrolnimi vzorci. Namen raziskave je bil ugotoviti, katere anatomske spremembe so povezane s prisotnostjo gliv in kako se odražajo v strukturi lesnih tkiv. V ta namen smo pripravili mikroskopske preparate vzorcev trte, jih obarvali z astra modrim in safranin rdečim barvilom ter analizirali s svetlobno mikroskopijo. Pri prizadetih vzorcih smo opazili stanjšanje in razgradnjo celičnih sten, pogostejši pojav til ter anatomske spremembe, povezane s kompartmentalizacijo in nastankom reakcijskih con. Pri najbolj prizadetih vzorcih je bila prisotna napredna razgradnja lesnih vlaken in izrazita deformacija strukture ksilema. Kontrolni vzorci so ohranili bolj homogeno in manj spremenjeno anatomsko zgradbo. Ugotovitve kažejo, da so s prisotnostjo gliv povezane izrazite sekundarne anatomske spremembe ksilema vinske trte, ki lahko vplivajo na njegovo funkcionalnost. Rezultati raziskave ponujajo vpogled v anatomske spremembe in procese razgradnje lesnih tkiv vinske trte ter prispevajo k boljšemu razumevanju odziva lesa na prisotnost gliv. This study investigates anatomical changes in grapevine (Vitis vinifera) wood associated with the presence of fungi, focusing on a comparative analysis between affected and control samples. The objective was to identify anatomical changes associated with fungal presence and to assess how these are reflected in the structure of woody tissues. To achieve this, microscopic sections of grapevine samples were prepared, stained with Astra Blue and Safranin, and analyzed using light microscopy. In affected samples, we observed thinning and degradation of cell walls, an increased presence of tyloses, and anatomical changes associated with compartmentalization and reaction zone formation. In the most severely affected samples, advanced degradation of wood fibers and pronounced deformation of xylem structure were observed. In contrast, control samples retained a more homogeneous and less altered anatomical structure. The findings indicate that the presence of fungi is associated with pronounced secondary anatomical changes in grapevine xylem, which may affect its functionality. This research provides insights into anatomical changes and degradation processes in grapevine wood and contributes to a better understanding of wood responses to the presence of fungi. trta Vitis vinifera les glive Vitis vinifera wood fungi true false false [E.
