Genetic consequences of rarity in Aster furcatus (Asteraceae), a threatened, self-incompatible
These results suggest that there are differences between genotypes in the self-incompatible
fail to penetrate stylar tissue in self-incompatible
As a consequence, their seed set and compatible index were 0, indicating that the 15 cultivars were completely self-incompatible
. Although the other 9 cultivars produced selfing seeds, seed sets and compatible indexes of five cultivars ("QX-081," "QX-006," "QX-003," "Q10-33-2," and "Nannongxiangbin") were very low, much less than 0.5%, showing that the five cultivars were nearly self-incompatible
DISCUSSION--Species of Asteraceae have been considered to be predominantly self-incompatible
; thus, they require vectors for their pollination (Proctor and Yeo, 1972; Burtt, 1977; Richards, 1986; de Nettancourt, 2001).
In addition, using the self-incompatible

Proponents of effective pollination limitation argue that early fruit abortion in self-incompatible
species is due largely to insufficient numbers of compatible pollinia reaching stigmatic chambers.
Our study indicates Galax is self-incompatible
and insect pollinated.
