Abstract.Oenothera plants grown as shoot meristem cultures on media having a low calcium concentration had a reduced abundance of raphides when compared to greenhouse-grown plants or shoot meristem cultures grown on higher concentrations of calcium. Plants from the low-calcium media also yielded a higher proportion of intact chloroplasts during subcellular fractionation.
