Offspring traits

The data result from a field experiment to examine the effects of pollination intensity on both quantity and quality of progeny. We manipulated pollen receipt to stigmas of the wind-pollinated dioecious plant Mercurialis annua by varying the distance of females from males. We then compared seed size and number, seedling growth and allocation to male and female function, for the progeny produced by females subjected to different pollination intensities.

Data collected on the seeds and resulting offspring produced by the maternal plants exposed to different level of pollination intensities.

Definitions of column headings
seedID: Unique ID of the seed
Mdirection: Directional transect on which the maternal plant was setup
Mdistance: Distance from pollen source of the maternal plant (in meters)
motherID: Unique ID of the maternal plant
Mpollination: Pollination intensity treatment of the maternal plant; h=high (0.2 and 0.5m from males); l=low (20 and 25 m from males)
seedmass: mass of the individual seed (in mg)
seedcat: mass categories of the offspring as seed: A <2; 2<=B<2.49; 2.5<C<2.99; 3<D<3.49; 3.5<E<3.99; F>4
germ: germination status of the seed (0=not germinated; 1=germinated)
time-germ: number of days between sowing and full expansion of the cotyledons
offspringID: Unique ID of the offspring (for germinated seeds)
plotID: ID of the plot in which the seedling grew once in the common garden; ID range from 1 to 54, with 16 positions per plot
position: Position of the offspring within its plot (ranges from 1 to 16)
treatment: whether the offspring was growing with a competitor (hermaphrodite) or not. If the competitor survived (treatment = I), if it died due to transplantation issues (treatment =I0); if the offspring grew alone (treatment = C).
offspring_sex: Sex of the offspring (M=male; F=female)
offspring_survival: 1= the offspring was still alive at the end of the experiment; 0= the offspring died in the course of the experiment
offspring_height: Height of the offspring (in cm) on the day of harvesting
offspring_mass: Mass of the dried offspring (in g), including reproductive parts (seeds for females)
offspring_veg_mass: Mass of the dried offspring (in g) without reproductive parts
offspring_total_seed_mass: Mass of the seeds produced by the offspring (in g)
offspring_seed_number: Number of seeds produced by the offspring (count)
offspring_male_allocation: Mass of male inflorescences (inflorescences stems + dried flowers) in mg

本数据集源自一项野外实验，旨在探究授粉强度对子代数量与质量的影响。研究人员通过调整雌性植株与雄性植株的间距，对风媒传粉的雌雄异株植物一年生山靛（Mercurialis annua）的柱头花粉接收量进行了操控。随后，研究人员比较了不同授粉强度处理下雌性植株所产生子代的种子大小与数量、幼苗生长情况，以及对雌雄功能的资源分配。
