Note on the Culture of Lychnis Embryos

The additional literature cited in two recent reviews by White (2, 3) indicates the growing interest in tissue culture since his original review (1) of the subject in 1931. Although embryo culture is not tissue culture in the true sense of the word, the approach to the problems and the technics employed, are so similar that White has summarized the literature on embryo culture, and all other studies approaching a true tissue culture, in these articles. The present study was begun in an attempt to obtain normal plants from immature Lychnis embryos dissected from developing seeds. Although immature embryos of other genera have been cultured, primarily those of the Gramineae and Cruciferae, apparently no effort has been made to culture embryos of any genera of the Caryophyllaceae
