Figures & data
Figure 1 Mean seed output expressed as (A) the percentage of capitula per shrub that set one or more achenes (%CA), (B) the number of achenes per capitulum per shrub (NAC), and (C) percentage seed set (% of ovaries of open florets per shrub that set seed) (%SS), and seed quality expressed as (D) weight of achenes per capitulum per shrub (mg) in control (white bars) and hand supplementary pollinated (gray bars) shrubs of the insect-pollinated dwarf shrub Chuquiraga oppositifolia (Asteraceae) at a 2600m elevation site (Valle Nevado–33°21′S, 70°16′W) in the lower alpine belt (subandean scrub vegetation belt), Andes of central Chile. Bars are means +1 SE. *significant differences (P< 0.05). Each treatment had 15 replicates.
Figure 2 Mean seed output expressed as (A) %CA, (B) NAC, and (C) (%SS), and seed quality expressed as (D) weight of achenes per capitulum per shrub (mg) in shrubs of Chuquiraga oppositifolia at three different sites in the lower alpine belt (subandean scrub vegetation belt) in the central Chilean Andes. Lagunillas (LA—33°33′S, 70°16′W) at 2000m (white bars), Farellones (FA —33°19′S, 70°17′W) at 2300m (light gray bars), and Portillo (PO—32°51′S, 70°10′W) at 2550m (dark gray bars). Bars are means +1 SE. Treatments (sites) sharing the same letter for any given response variable do not differ significantly (P> 0.05). Ten replicate shrubs were monitored at each site.
