An Analysis of the Role of Electromagnetic Radiations in the Mating Reaction of Paramecium bursaria

摘要: T IHE mating reaction of Paramecium occurs when sexually active animals opposite types are mixed together. Typically, the stick, one type to another, forming large agglutination masses. These masses break down into smaller clumps, until each consists only two conjugants type. The separate after a reciprocal exchange pronuclei. Numerous investigators have concentrated their attention (predominantly cytological and genetical) on late phases reaction-conjugation-separation process (for general review see Sonneborn, 1947); few examined in detail steps initiating process. principal contributions this area been made by Metz his associates, several which (Metz, 1946, 1947, 1948; Foley, 1949; Butterfield, 1950) discussed later section paper.
