Aberrant floral organ no. and morphology were observed in bothsin1 and caf mutants, regardless of genetic background (either La-er or Co-gl). For each phenotypic class, n = 50 flowers and the data are presented as the mean organ number ± sd. se, Sepals; se/pe, sepaloid petals; pe, petals; pe/st, petaloid stamen; st, stamen; st/ca, stamenoid carpels; ca, carpels. The frequency at which morphologically abnormal floral organs arose is noted. Data were analyzed using the Fisher-Behrens procedure, with an asterisk representing the d value significant at the 95% level, and two asterisks representing the d value significant at the 99% level (Campbell, 1989).
