20.500.12556/RUL-177172 Morphophysiological and anatomical responses of Quercus suber L. seedlings under drought stress conditions Morfofiziološki in anatomski odzivi sadik hrasta plutovca (Quercus suber L.) v razmerah sušnega stresa This study was performed to investigate the effects of drought stress on behavior of cork oak seedlings (Quercus suber L) originatd from five different ecogeographical zones in Algeria (Tlemcen, Oum Tboul, Jijel, Dradra, Tizi Ouzou). The resilts showed that drought stress affected both the height and collar diameter, relative growth in height and diameter of stems in provenances Oum Tboul, Tlemcen and Tizi Ouzou, also a decrease in leaf number and fresh and dry masses, shoot to root dry mass ratio and the relative water content for all stressed plants from all provenances. However, it has been noted a significant increase in length of the main root in all provenances. As well as a decrease in the total chlorophyll and carotenoids contents and increase in proline content especially in Tizi Ouzou and Tlemcen provenances under water limitation. Moreover, the anatomical study revealed a reduction in vessel diameter of rootsin all stressed plants from all provenances. The five cork oak provenances studied showed different morpho-physiological and anatomical traits that could be linked to the environnemental conditions of provenances. cork oak ecogeographical zones drought stress root vessel diameter hrast plutovec ekogeografske cone sušni stres premer koreninskih trahej true false true Angleški jezik Slovenski jezik Neznano 2025-12-17 10:30:11 2025-12-17 10:30:17 2025-12-28 04:07:49 0000-00-00 00:00:00 2025 0 0 14 str. no. 4 Vol. 121 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 63 1854-1941 10.14720/aas.2025.121.4.22473 261814787 View_of_Morphophysiological_and_anatomi...lings_under_drought_stress_conditions.pdf View_of_Morphophysiological_and_anatomi...lings_under_drought_stress_conditions.pdf 1 969F1711100CD971A88817E4C8435876 6692e4b27ea351ea8614d037aa0750f4651755e46f3eba2baa28c23f39b12abd 1e663ffd-db2b-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=224067 https://journals.uni-lj.si/aas/article/view/22473/19898 1 916540cd-db2a-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=224066 Biotehniška fakulteta Acta agriculturae Slovenica 0 0 0
