20.500.12556/RUL-92887 Wood formation in Norway spruce studied by pinning technique and intact tissue sampling method Seasonal dynamics of xylem formation were studied at a cellular level in Norway spruce (Picea abies) from the lowland forests Sorsko polje (350 m a.s.l.) and the sub-alpine site Pokljuka (1200 m a.s.l.) in Slovenia during the growing season 2003. Th e pinning technique and sampling of intact tissue were performed at weekly intervals to assess the usefulness of both methods for examining wood formation. Pinning induced desiccation of diff differentiated xylem, necrosis of cambial cells and undifferentiated xylem derivatives, and formation of callus, traumatic resin canals and wound-wood. The border between cambial cells and radially expanding cells located inside the callus was a reliable mark for defining the xylem increment reached from the time of wounding. Intact tissue sampling was superior for precise investigations of cambial activity, various developmental stages of tracheids,and for secondary phloem formation. nastanek lesa kambijeva aktivnost smreka Picea abies intakna tkiva metoda pining pining true false true Angleški jezik Slovenski jezik Članek v reviji 2017-07-06 14:35:10 2017-07-06 14:35:12 2022-08-10 01:18:02 0000-00-00 00:00:00 2007 0 0 Str. 1-9 no. 2 Vol. 52 2007 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*81(045)=111 1336-4561 1905830 1157257 Gricar_etal_Wood_Res_2007_pinning_ITSM.pdf Gricar_etal_Wood_Res_2007_pinning_ITSM.pdf 1 2EDEE67F04384AA8D99C82CE9F274B18 38ac33b0597a6698f6b209b22f86e2c06c8e438b17839c5af2bedd166cd38c06 73eccdce-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/8a8de0a5-a27a-4f53-8f02-e864403b4841 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=101046 Biotehniška fakulteta 0 0 0
