Some observations on the zoospores from the zoosporangia ofPlasmodiophora brassicae Woron

Abstract

Het onderzoek had ten dcel het gedrag van de zoosporen uit de zoosporangia vanPlasmodiophora brassicae na te gaan. Aangetaste worteltjes van jonge koolplanten, opgekweekt in zwaarbesmette grond, werden goed afgespoeld en in stukjes ter lengte van 2–3 cm geknipt. Hiervan werden waterpreparaten gemaakt, waarin na ongeveer 30 min. de zoosporen uit de zoosporangia begonnen vrij te komen. Het merendeel van de zoosporen had een lange en een korte zweepdraad, maar bij sommige zoosporen werden twee lange en twee korte zweepdraden waargenomen. Enkele malen werd waargenomen, dat twee zoosporen, door een draadvormige verbinding aan elkaar gekoppeld, op korte onderlinge afstand gepaard rondzwommen. In preparaten met gekleurde zoosporen werden behalve zoosporen met een lange en een korte zweepdraad, ook zoosporen met twee lange en twee korte, drie lange en drie korte en zelfs vier lange en vier korte zweepdraden aangetroffen. Op grond van deze waarnemingen wordt — in overeenstemming met hetgeen van de nauw aanP. brassicae verwante schimmelSpongospora subterranea bekend is — geconcludeerd, dat samengestelde zoosporen ontstaan doordat twee of meer enkelvoudige zoosporen versmelten. Het is niet uitgesloten, dat deze versmelting van zoosporen het begin is van een geslachtelijke phase in de levensloop van de schimmel, maar een kernversmelting in de samengestelde zoosporen kon niet worden aangetoond.
