Abstract

SINCE the production of new morphological types in the course of grafting experiments of tomato on Solanum nigrum in 1910 by Winkler1 and the description of the difference between the white-edged and solid-green leaf varieties of Pelargonium zonale by Baur2, the spontaneous occurrence of chimæras, particularly in fruits and flowers, has been reported in many crops and ornamental plants. More recently, Sativa and Blakeslee3 have reported the induction of chimæras by treatment of germinating seed with colchicine. The occurrence of a chimæra in tea of the type described, however, has not been previously reported. Gadd4, in a discussion of non-infectious chlorosis in tea, says: “The yellow colour is due to lack of chlorophyll, though why it should not develop normally in particular zones is not known”.
