05): Tupataro 62%, Yuriria 57%, and Jeruco 54%, which suggests high autogamy in these populations.
Autogamy may provide reproductive assurance, especially if it occurs without insect visitation (autonomous autogamy).
These barriers prevent spontaneous contact between the two sexual parts of the flower, making autogamy very unlikely, as described by Venturieri and Ribeiro Filho (1995) for cupuacu.
The reproductive system experiment included four pollination treatments: autogamy (A), geitonogamy (G), xenogamy (X), and open control (O).
Significance difference between the percentages obtained from xenogamy, autogamy and the control experiments were evaluated by comparison formula between two percentages, with a 5% significance difference level (PAGANO; GAUVREAU, 2004).
It is also important to consider that species with simplified morphologies are frequently r-strategists, with a quantitative investment in their offspring, usually without autogamy barriers and easy germination, featuring coloniser species that rapidly establish themselves in a new environment.
Bush and Beach (1995) suggested that epiphytism generally favors autogamy, as well as Madison (1979) who suggested that ant-garden dwelling epiphytes usually set self-seeds, which is probably true in some species of Aechmea (A.
This research also helped to identify unique traits including autogamy and photoperiod insensitivity in birdsfoot trefoil, and made possible the release of enhanced germplasm of narrowleaf and big trefoil, salt-tolerant narrowleaf trefoil, and rhizomatous and drought tolerant birdsfoot trefoil.
