Data from the experiment where the effect of bract manipulation on seed mass of hand-pollinated blossoms was investigated.

FemaleID: identity code of the maternal plant MaleID: identity code of the paternal plant ped1: peduncle diameter first measurement ped2: peduncle diameter second measurement poll: pollination date crossID: identity code for the cross (equivalent to a unique blossom identity code) treatcode: code for the treatment: cut = bracts removed; cutcont= control for the cutting experiment; bag = blossom shaded; cont = non-manipulated control harvest: date harvesting seedID: identity number for each seed within each blossom seedset: blossom seed set seedmass: mass of individual seeds in mg date.weight: seed weight measuring date ped: average of the two measurements of the peduncle diameter time: maturation time in days (harvesting date – pollination date
