Elas foram incubadas à temperatu ra de 23 +/- 2°C, sob luz fluorescente por um período de 30 a 45 dias. As plântulas obtidas foram repicadas para meio Knudson, permanecendo em incubação por quatro meses e, em seguida, transferidas para meio fresco, até atingirem tamanho para aclimatação. O cultivo &lt;em&gt;in vitro&lt;/em&gt; de ambas as espécies foi considerado viável, havendo comportamento diferente entre as espécies, em relação à produção de protocormóides, níveis de oxidação e crescimento &lt;em&gt;in vitro&lt;/em&gt;. Os resultados mostraram que um meio me nos concentrado como Knudson pode ser utilizado sem adição de reguladores de crescimento para produção de mudas tanto para &lt;em&gt;Cattleya&lt;/em&gt; &lt;em&gt;walkeriana&lt;/em&gt; quanto para &lt;em&gt;Cyrtopodium&lt;/em&gt; &lt;em&gt;palmifrons&lt;/em&gt;.&lt;/p&gt; &lt;p class="western" align="justify"&gt;PALAVRAS-CHAVE: Orchidaceae; cultura de tecidos; orquídea.&lt;/p&gt;<br>&lt;!-- @page { margin: 2cm } --&gt; &lt;p class="western" align="justify"&gt;Seeds of &lt;em&gt;Cattleya&lt;/em&gt; &lt;em&gt;walkeriana&lt;/em&gt; and &lt;em&gt;Cyrtopodium&lt;/em&gt; &lt;em&gt;palmjfrons&lt;/em&gt; (&lt;em&gt;Orchidaceae&lt;/em&gt;) were aseptically transferred to culture medium Knudson, MS (Murashige&amp; Skoog) and MS supplemented with IAA (l, 15 and 30 mg L&lt;sup&gt;-1&lt;/sup&gt;) and kinetine (0.25, 5 and 10 mg L&lt;sup&gt;-1&lt;/sup&gt;) for germination. They were kept at room temperature (23 +/- 2°C) under fluorescent light for 30 to 45 days. The seedlings were transferred to pots containing culture medium Knudson and incubated for four months at room temperature and transferred to fresh culture medium until the seedlings attained approximately 1.0 to 2.0 cm size for climatization.
