Summary

The addition of a seaweed concentrate to tissue culture medium improved the quality of potato plantlets. Season, cultivar and explant type affected the most beneficial concentration applied. Concentrations higher or lower than the optimum were less beneficial or adverse to plantlet quality. Terminal buds were more sensitive to non-optimum seaweed application than axillary buds. Decreased water loss from plantlets was one of the potential benefits of seaweed concentrate in vitro, thus improving establishment after transplanting.
