20.500.12556/DKUM-52829 Expression of disease symptoms on different apple cultivars infected with apple proliferation phytoplasma Izražanje bolezenskih znamenj pri jablanah različnih sort okuženih z Apple proliferation fitoplazmo An expression of Apple proliferation (AP) symptoms in the infected young apple trees of 7 cultivars was studied. Two types of symptoms were observed in infected trees; AP specific (changes in size and number of leaf stipules and witches-broom formation) and non-specific symptoms (changes in leaf size, shape and colour, formation of rosettes and stunting of shoots). The percentage of infected trees that expressed one or more AP-specific symptoms was 18.9-75.5 % in one-year old trees, 39,4-87 % in two-year, and 44,8-89,7 % in three-year old trees. The expression of non-specific symptoms was similar (43,2-65,3 % in one-year, 57,6-85,2 % in two-year and 62,1-87,5 % in three year old trees). apple proliferation phytoplasma apple disease symptom expression true false false Inštitut za hmeljarstvo in pivovarstvo Angleški jezik Slovenski jezik Delo ni kategorizirano 2015-07-10 18:27:14 2015-07-10 18:27:14 2022-06-01 03:07:38 2019-07-11 07:54:46 2007 0 0 str. 43-53 št. 14 14 2007 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 634.10:631.537:632.2/.3:632.911 15881986 2613036 0350-0756 URN:SI:UM:DK:2B3H4GEC http://www.dlib.si/details/URN:NBN:SI:DOC-M2FSGD0I 1 https://dk.um.si/Dokument.php?lang=slv&id=77389 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
