Effects of four cucurbitacins, which occur mostly in seeds of Cucurbitaceae, and of cucurbitaceous tissue extracts on somatic embryony in tissue cultures of carrot,Citrus microcarpa andRanunculus sceleratus are described. Thin layer chromatographic analyses showed that the nucellar extract and the integuments of Luffa cylindrica contain cucurbitain B. Studies with the extracts on all the three tissue culture systems have corroborated the observed inhibitory effect of cucurbitacins on somatic embryony. The role of cucurbitacins in plant embryogeny, and in the control of zygotic or adventive embryony in crop species is discussed.
