Greenhouse Study
Bud development time (Figure 3) and flower longevity (Figure 4) were sig-
nificantly (P < 0.05) shorter in selfing annuals in all of the families except
the Fabaceae (P = 0.123 and P = 0.056 respectively). Selfing annuals also had
significantly shorter bud development times (Figure 5), and floral longevities
(Figure 6) in three of the four genus pairs. Selfing and outcrossing annuals of
the genus Ipomoea did not differ significantly in either bud development time
(P = 0.402) or flower longevity (P = 0.328). Age at first flower was not signifi-
cantly related to mating system for any of the family or genus comparisons
(P > 0.05; data not shown).

Mean (SE) bud development time for selfing and outcrossing species within each of 5 families. For
each species, n = 4 or 5. P - values are from ANOVA.
