Formation of Anthocyanins from Cells Cultured from Different Parts of Strawberry Plants

摘要

ABSTRACTAnthocyanin formation and structural identification were investigated in the cultured strawberry,Fragaria unannssacv Shikinari. Friable callus tissues were obtained from apical meristems, leafs, and petioles grown on LS agar medium with 2,4‐dichlorophenoxyacetic acid and benzyladenine. Using these calli, effects of auxins and cell inoculum size on pigment production were studied in suspension culture. Anthocyanin was produced under 8000 lux after preculture for 3 wk under 800 Iux in suspension culture. The main extracted pigment was identified as a peonidin‐3‐glucoside and the second major pigment was a cyanidin‐3‐glucoside by FABMS and NMR. Anthocyanin production was stimulated by 2,4‐dichlorophenoxyacetic acid and its yield was about three times that of indole‐3‐acetic acid. An inoculum rate of 2g (fresh weight)/100 mL LS medium resulted in highest pigment production. The callus derived from the leaf was much higher in anthocyanin production than the others tissue
