Self-pollination of the orchid Cycnoches haagii from Brazilian Cerrado results in albino phenotype seedlings

Abstract Cycnoches haagii Barb. Rodr. is an epiphytic orchid very targeted by collectors, but no reference was found in the literature about its reproductive biology. Thus, purpose of this study to obtain initial information regarding pollination types and influence on seed viability native Brazilian Cerrado, order enable future propagation preservation programs. Pollination among flowers same plant (geitonogamy) or different plants (xenogamy) were carried out. Seeds extracted from capsules sown B&G medium, with full half strength. geitonogamic resulted 25% albino protocorms consequently seedlings. This phenomenon did not occur seedlings derived xenogamic pollination. Pigment analysis showed that even presented chlorophylls carotenoids, however, significantly minor concentrations, 16% 37% respectively, relation green Geitonogamic pollinations C. viable seeds high germination percentage (90%) under vitro conditions. The chlorophyll normal only, can be recommended at conservation On other hand, although should avoided programs species as it leads seedlings, a interesting system phenotype, material investigation.
