Parental Effects on Progeny Sex Ratio, Emergence, and Flowering in Silene Latifolia (Caryophyllaceae)

1) The dioecious perennial, Silene Latifolia (Caryophyllaceae) was tested to determine whether parental nutrient condition and pollination position affects sex ratio, emergence date, and age at first flowering of the progeny. 2) Parental plants were grown under two nutrient regimes (either full-strength or 25% fertilizer). One flower on each female plant was pollinated on the basal portion of the receptive stigmatic lobes, and another on the distal region. Seeds from the mature capsules were grown in the glasshouse until flowering and emergence date, flowering date, and sex were recored for each individual. 3) Neither the position of pollen application nor the nutrient condition of the parents affected progeny sex ratio
