Abstract
Abstract Embryos, pseudobulbils, and embryogenic callus were obtained by in vitro culture of undeveloped ovules excised from ripe fruits of the navel orange group ( C . sinensis [L.] Osbeck) and lemon (C. limon [L.] Burm. f.). Initial culturing was on Murashige & Skoog (MS) medium in 1% agar. Large numbers of seedlings were produced by subculturing the embryos, pseudobulbils, and embryogenic callus on fresh MS medium with added 6-methylaminopurine.
