Sažetak Popis štitastih uši na domaćinima iz roda Quercus L. sastavljen je od svih dostupnih literaturnih podataka faunističkih istraživanja štitastih uši u Hrvatskoj i podataka faunističkih istraživanja koja su trajala od 2005. do 2014. Prema literaturnim podacima u Hrvatskoj registrirano je 15 vrsta štitastih uši na hrastu. Istraživanjima je utvrđeno 12 vrsta štitastih uši, od kojih je u odnosu na vrste iz literaturnih podataka registrirano šest novih. U ovom trenutku popis štitastih uši na hrastovima obuhvaća 21 vrstu iz četiri porodice kako slijedi: porodica Asterolecanidae: Asterodiaspis ilicicola (Targioni Tozzetti 1888), A. quercicola (Bouche 1851), A. variolosa (Ratzeburg 1870), porodica Coccidae: Coccus hesperidum Linnaeus 1758, Eulecanium tiliae (Linnaeus 1758), Parthenolecanium rufulum Cockerell 1903, Pulvinaria sericea (Fourcroy 1785), porodica Diaspididae: Chionaspis etrusca Leonardi 1908, C. lepineyi Balachowsky 1928, C. salicis (Linnaeus 1758), Diaspidiotus alni (Marchal 1909), D. bavaricus (Lindinger 1912), D. ostreaeformis (Curtis 1843), D. zonatus (Frauenfeld 1868), Gonaspidiotus minimus (Leonardi in: Berlese & Leonardi 1896), Lepidosaphes beckii (Newman 1869), L. ulmi (Linnaeus 1758), Targionia vitis (Signoret 1876) i porodica Kermesidae: Kermes quercus (Linnaeus 1758), K. roboris (Fourcroy 1785) i K. vermilio Planchon 1864. U srpnju 2014. godine, zamijećeno je propadanje hrasta crnike u Poreču. Nakon što je obavljen vizualni pregled, uzeti su uzorci. Dijagnostička analiza, koja je obavljena u Laboratoriju za zoologiju Zavoda za zaštitu bilja, pokazala je da se radi o štitastoj uši crnike K. vermilio. Budući da je ovo prvi nalaz K. vermilio u Hrvatskoj, vrstu možemo smatrati novim članom hrvatske entomofaune. Ova štitasta uš napada zimzelene domaćine iz roda Quercus, ponaj­prije Quercus ilex L. Široko je rasprostranjena u zemljama Mediteranskog bazena. U prošlosti, štitasta uš K. vermilio imala je značajnu gospodarsku važnost kao izvor crvene boje za tkaninu, no danas ima status invazivnog gospodarski značajnog štetnika.

This  study deals with the biomass estimation of the understory species of Pinus halepensis    forests in the Kassandra peninsula, Chalkidiki (North Greece). These  species are: Quercus    coccifera, Quercus ilex, Phillyrea media, Pistacia lentiscus, Arbutus  unedo, Erica arborea, Erica    manipuliflora, Smilax aspera, Cistus incanus, Cistus monspeliensis,  Fraxinus ornus. A sample of    30 shrubs per species was taken and the dry and fresh weights and the  moisture content of    every component of each species were measured, all of which were processed  for aboveground    biomass data. Then several regression equations were examined to determine  the key words.

Murashige And Skoog’S Medium

The proliferation of parenchymatous foliar tissue of Quercus ilex was obtained from current year leaves taken from old trees and cultivated in vitro on modified Murashige and Skoog's medium supplemented with benzylaminopurine (4 mg ∙ L−1) and naphthyl acetic acid (0.5 mg ∙ L−1). Only the fragments cultured in October reacted. The neoformations only appeared on calluses that had not been subcultured for 7 months. Primary nodules arising on these calluses were removed and subcultured on the same medium either in the dark or in the light. In the dark only, they produced secondary nodules, which were the source of somatic embryos both in light and dark. Presently, they seem to regulate their structure in the dark but they do not develop in a way that leads to germination.
