| Popis: | English ivy (Hedera helix L.) plants with symptoms of vein clearing on the leaves have recently been found in the surroundings of Split (Croatia, Yugoslavia). These symptoms are characteristic of some diseases which are caused by rhabdoviruses. Therefore, we prepared ultrathin sections of leaves with vein clearing symptoms and we found rhabdoviruses in these leaves. The rhabdovirus particles were located in the cytoplasm. They were 60 to 70 nm wide but the length of virus varied greatly. Afterwards, we succeeded in transmitting this virus mechanically by means of corresponding buffer solution and sodium ascorbate to a suitable test According to these data wre could conclude that the rhabdovirus found is ivy vein clearing virus which has been first detected and described in Italy. Yugoslavia is the second state in which this rhabdovirus has been found. Primjerci bršljana (Hedera helix L.) sa simptomima prosvjetljavanja lisnih žila nađeni su nedavno u okolici Splita. Ti su simptomi karakteristični za neke bolesti koje izazivaju rabdovirusi. Zbog toga smo priredili ultratanke presjeke kroz listove s prosvjetljavanjem žila i pronašli smo rabdoviruse u tim listovima. Cestice rabdovirusa nalazile su se u citoplazmi. Bile su 60 do 70 nm široke, ali je dužina virusa bila vrlo različita. Poslije toga uspjeli smo prenijeti taj virus mehanički pomoću odgovarajuće puferske otopine i natrijeva askorbata na pogodnu pokusnu biljku. Na osnovi tih podataka mogli smo zaključiti da nađeni rabdovirus pripada virusu prosvjetljavanja žila bršljana (ivy vein clearing virus) koji je najprije nađen u Italiji. Jugoslavija je druga zemlja u kojoj je taj virus otkriven. |
