| Abstract;Thi study investigated the changes in endogenous auxin concentration during embryogenesis of citrus(Citrus sinensis Osb.) in tissue culture. Embryogenic callus(EC) was induced from ovules of 'Trovita orange' and 'Oomishima navel'. In both varieties, the EC having greater capacity for embryogenesis had a correspondingly higher endogenous indole-3-acetic acid(IAA) concentration. When the EC in 'Washington navel' and 'Oomishima navel' were cultured on hormone-free media which can induce embryogenesis, the IAA concentration increased for 2 days, then rapidly decreased and stabilized 14 days later. These results suggest that the decrease in IAA concentration is closely related to citrus embryogenesis. (author abst.) |
