Evidence of Delayed Selfing in Fumana juniperina (Cistaceae)

Several aspects of the reproductive biology of Fumana juniperina were analyzed to find out whether delayed selfing occurs within a representative natural population in southwest Sardinia. Similar fruit set was obtained after autonomous, within‐flower, and between‐flower self‐pollination (0.35, 0.53, and 0.46, respectively), cross‐pollination (0.45), and control (0.39). Seed set and seed mass did not differ significantly between pollination treatments ( \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 \selectfont} \DeclareTextFontCommand{\textcyr}{\cyr} \pagestyle{empty} \DeclareMathSizes{10}{9}{7}{6} \begin{document} \landscape

No pollinators were seen visiting the flowers during the 42‐h observation period, and the stigmatic pollen load on open‐pollinated flowers, collected after the petals had fallen and before anther and stigma contact had occurred, was not enough to fertilize all the ovules. Low levels of inbreeding depression were found for fruit set ( \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 \selectfont} \DeclareTextFontCommand{\textcyr}{\cyr} \pagestyle{empty} \DeclareMathSizes{10}{9}{7}{6} \begin{document} \landscape
