From: Range expansion decreases the reproductive fitness of Gentiana officinalis (Gentianaceae)
The seed-set ratio of G. officinalis under 3 pollination conditions among the 4 plots. (A) represents natural pollinator, (B) depicts self-pollination, (C) shows cross-pollination, and (D) represents supplemental pollination. Data were collected from 2 buds at the same position on each inflorescence (a total of 30 inflorescences) on different plants in each plot, with one bud for natural pollination and the other for supplemental hand pollination when stigmas opened until permanent flower closure.
