20.500.12556/RUL-68639 Detecting changes in tree health and productivity of silver fir in Slovenia Cambial electrical resistance (CER) was used as an objective measure of vitality of silver fir (Abies alba Mill.) in the forests of Slovenia. Trees were rated during the growing season by CER and a subjective crown status index (CSI). Both CER and CSI were inversely correlated to annual ring width increment. Using both CER and CSI, fir were assigned to vitality and vigor categories. Inferences made from these categories and radial growth trends indicated that ring growth decreased prior to the development of canopy symptoms. This decrease in ring growth would have been detected as an increase in CER. This pattern of decline is consistent with the decline of trees due to chronic belowground stress. Variation in CER was due both to the vascular cambium and to the thickness of the nonconducting phloem. tla jelka Abies alba (Mill.) zdravstveno stanje produkcijska sposobnost vitalnost kambij kambijeva cona električna upornost merjenje metoda dela Slovenija true false false Parey Angleški jezik Nemški jezik Delo ni kategorizirano 2015-07-10 21:09:04 2015-07-10 21:09:04 2022-08-01 12:52:40 0000-00-00 00:00:00 1999 0 0 Str. 189-197 No. 3 Vol. 29 1999 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630 0300-1237 512422 Torelli--Shortle-1999EJFP-ABAL-CER.pdf Torelli--Shortle-1999EJFP-ABAL-CER.pdf 1 3D021F9D56A2B6BA91F3911208E721E6 e59823ed60b78082e4b6807836bf8ebb508bdcc2be4dede6ecb21423b036ecbe 67bd9584-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/1fd25590-e1bc-49c7-a331-0dc33dd7a32e https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=100829 Biotehniška fakulteta 0 0 0
