formation; SC = shoot cluster; SCR = shoot cluster with roots; CSCI = callus
with shoot cluster initials; CIS = corm-like structure (< 10 mm); CAI = callus
appearing incompetent; CPE = callus with potential embryogenesis; PDE =
potential direct embryogenesis; CSGR = cultures showed growth response.
Potential embryogenesis refers to cultures that appeared to develop embryolike
structures (Figure 5.7).
Table 6.1: The effect of different temperatures and media composition on the
in vitro formation and growth of Romulea minutiflora corms. Data shows the
means ± the standard error. Letters indicates significant differences between
treatments according to Duncan’s multiple range test.
Table 6.2: Percentage corm induction for Romulea minutiflora shoots cultured
on medium supplemented with growth retardants.
Table 6.3: The effect of different temperatures and media composition on the
in vitro formation and growth of Romulea sabulosa corms. Data shows the
means ± the standard error. Letters indicate significant differences between
treatments according to Duncan’s multiple range test.
Table 6.4: Cultures with multiple corm formation for Romulea sabulosa. This
shows the percentage of corm formation in cultures in which corm formation
observed (Total cultures with corms) and the average number of corms
produced in instances of multiple corm formation.
