Anthers containing uninucleate microspores of eggplant cv.'Wase-Shinkuro' were cultured on MS supplemented with 0.02mg/1 2,4-D and kinetin,3% sucrose and 0.2% Gelrite with high and low temprerature treatments to increase number of haploids,in early August and September and on November 4,1992.Anthers plated were kept heated at 35℃ for 48h in early November,and callus and embryoid were formed from microspores.The frequency of anthers foming callus was as high as 28% in treated anthers,but 14% in non-treated ones.Embryoids were obtained only in treated anthers,and the frequency of anthers forming embryoid was 5.1%.On the other hand,low temprerature pretreatments at 4℃ for 0,5 or 10days to flower buds in summer season were ineffective for embryoid formation and inhibitory for callus formation with treatement for langer periods.
