Summary
Cultures of 23 potato cultivars were examined for their responses to hormonal and osmotic growth inhibitors incorporated in media used for storage in-vitro. Cultivars differed in their tolerance of inhibitors and also in their growth on a Murashige and Skoog medium with 3% sucrose. Both osmotic and hormonal growth retardants restricted the development of shoot tips but there were significant cultivar x treatment interactions, indicating that the ranking of cultivars will vary with the media used. Such interactions may complicate the establishment of facilities for storage in-vitro. However, addition to the basal medium of 5 mg l−1 abscisic acid reduced both the overall mean scores and, more importantly, the between cultivar variance; its use in conjunction with low temperature shows promise as a method for conserving potato germplasm in-vitro.
