Total anthocyanin content (milligrams per gram dry weight tissue) of wild-type and transgenic plants from stamen and petal extract

Quantitative determination of total anthocyanin content in tobacco flowers has been performed by spectrophotometry at 535 nm. A purified standard of keracyanin was used as a control. Data are the means ± sd of four replicates. N.D., Not detected.
