    Notizen: Abstract An embryogenic callus was obtained from immature panicle of an interspecific hybrid (Oryza sativa x O. latifolia) F1. The medium consisted of HE salts supplemented with 2,4-D, NAA (each 2 mg/l), kinetin (3 mg/l), yeast extract (1360 mg/l) and casein hydrolyzate (300 mg/l). The callus was milk-white in colour compact and granulate in texture. Various developmental stage of embryoid, such as globular, heart-shape, scutellum-shape and mature embryoid were observed in an embryogenic callus. Plantlets were successfully regenerated from 1-month-old callus with more than 80% regenerational frequency in each subculture for 12 passages.

    Notizen: Abstract Cultured immature panicles of rice formed plantlets from spikelets without callus or embryoid formation on MS and HE media containing 2 mg/l each of NAA and kinetin. Developmental stage, ploidy of explant and plant growth regulators in the medium are the major factors affecting the frequency of spikelet budding in young panicle culture. It is suggested that spikelet budding occurs by the reversion of floral primordia to vegetative stage or by the formation of adventitious buds from epidermal cells.
