K elley , A. G., and S. N. P ostlethwait . (Purdue U., Lafayette, Ind.) Effect of 2‐chloroethyltrimethylammonium chloride on fern gametophytes. Amer. Jour. Bot. 49(7): 778–786. Illus. 1962.—2‐chloroethyltrimethylammonium chloride (CCC) promotes growth of fern gametophytes by stimulating the rate of cell division. The transition from filamentous to biplanar to triplanar cell division is hastened, resulting in earlier and more numerous gametangia on treated prothalli. Growth is stimulated in the range of 10 ‐4 m –10 ‐2 m CCC, with the optimal effect at 10 ‐3 m CCC. The time sequence of rhizoid production is altered by 10 ‐2 m CCC; the resultant production of rhizoids by prothalli treated with 10 ‐2 m CCC does not exceed that of controls.
