Samenvatting Door de als warkruid groeiende lauraceeCassytha filiformis werd van kokosnootpalm (Cocos nucifera), aangetast door ‘root(wilt)’, een mycoplasma-achtig organisme (MLO) overgebracht naar de toetsplantCatharanthus roseus. Hierop werden op de bladeren tussennervige, later ineenvloeiende vlekken en vroegtijdige bladval waargenomen. Uit onderzoek met de lichtmicroscoop en de elektronenmicroscoop kon de aanwezigheid van MLO's inCocos nucifera, Cassytha filiformis enCatharanthus roseus worden vastgesteld.
Notes:
Abstract A mycoplasma-like organism (MLO) was successfully transmitted through dodder laurel (Cassytha filiformis) from root (wilt) diseased coconut to periwinkle (Catharanthus roseus) plants. Symptoms caused by the organism in periwinkle were chlorotic spots in the interveinal areas and at vein endings of fully opened leaves, later coalescing into yellow patches, and premature leaf abscission. Light and electron-microscopic examination revealed the presence of MLOs in diseased coconut palms, dodder laurels and periwinkles.
