Literature review<br />

Table 2.7: Explant sources and PGR's used by various authors for direct shoot or meristimoid<br />

organogenesis in genera <strong>of</strong> Iridaceae. Where the concentrations <strong>of</strong> PGR's are not mentioned,<br />

the study included multiple species within the genus, each reacted differently to various<br />

concentrations. A question mark indicates that the specific parameter is not included in the<br />

described publication. The genera are grouped phylogenetically, with vertical text on the right<br />

showing classification.<br />
