Title

The germination rates of seeds from Eschscholzia californica plants located within habitats comprising habitats with different floral cover

Abstract

This dataset details the germination rates of seeds from Eschscholzia californica plants introduced to habitats comprising different floral cover. Data was collected in June 2015 at the Hillesden estate, Buckinghamshire, UK. Experimental arrays were introduced across the study site, Arrays comprised of three E.californica plants separated by 1m and arranged in a triangular formation. A total of sixteen arrays were introduced across four 100ha replicate blocks, each separated by >500m. At the centre of each block, four experimental arrays were placed at 50m intervals along a 150m transect laid symmetrically across the boundary between an established wildflower patch and bare, fallow ground or grazed grassland (two arrays within the florally rich habitat and two arrays within the florally poor habitat). After sixteen days plants were collected in and stored under glasshouse conditions. Upon fruit maturation, 20 seeds from each of the 48 field exposed plants was sown into compost and the number which successfully germinated was counted. The dataset was part of a larger experiment looking at the effect of floral resources on the pollination services to isolated plants.

Lineage

All open flowers were removed from the 48 E. californica plants, prior to their placement in pre-marked locations across the landscape. They remained in the field for 16 days to ensure full anthesis of new flowers and to allow for multiple pollination events. After this period, all fruit were tagged to ensure that only fruit development arising from the period of the field experiment were included in analyses. Plants were then collected and stored under controlled glasshouse conditions until fruit maturation. Upon maturation, tagged fruit were collected and 20 seeds from each of the 48 plants were sown into compost and kept under glasshouse conditions (as above). Germination was recorded daily over a 30-day period and any seeds which had not germinated after 90 days were recorded as non-viable. The germination success was expressed as a ratio between the number of seeds which successfully germinated against the number of seeds which failed to germinate in each of the 48 field exposed plants.
