Popis: A previous study showed that flowers of Campanula rapunculoides (Campanulaceae) are strongly self‐incompatible when the stigma first becomes receptive but are less strongly self‐incompatible as the flowers age. We deposited equivalent loads of self and outcross pollen onto either 1‐d‐old or 4‐d‐old stigmas and examined seed paternity using the PGI (phospho‐gluco‐isomerase) genetic locus. Pollen mixtures (50:50) on young flowers yielded only outcross progeny, indicating functional self‐incompatibility. Pollinations on the older stigmas, however, resulted in progeny arrays that departed significantly (χ2 test, \documentclass{aastex} \usepackage{amsbsy} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{bm} \usepackage{mathrsfs} \usepackage{pifont} \usepackage{stmaryrd} \usepackage{textcomp} \usepackage{portland,xspace} \usepackage{amsmath,amsxtra} \usepackage[OT2,OT1]{fontenc} \newcommand\cyr{ \renewcommand\rmdefault{wncyr} \renewcommand\sfdefault{wncyss} \renewcommand\encodingdefault{OT2} \normalfont \...
