Abstract

Bletia catenulata is a native Brazilian orchid whose populations have suffered from predatory collection. Aiming at elucidating aspects of its reproductive biology and the relation with seed germination, pollination tests were carried out in flowers of plants cultivated in a greenhouse. Manual cross and self-pollination resulted in high percentage of fructification (76.7-86.7 %), being only 26.7 % for natural pollination, in which the absence of pollinators, due to flower isolation, resulted in absence of fruits. In vitro seed germination for all fruits from the different pollination processes was low, being 8.6 % the highest percentage for protocorms. Thus, B. catenulata is self-compatible, resulting in viable seeds, but pollinator-dependent for sexual reproduction.
