This dataset includes data describing the berries and seeds of 172 juniper trees from nineteen populations across the UK and the proportional germination rate of each tree. Berries were collected and processed in 2015 and used in a germination trial that ran from 2015-2018.
Variables included: average berry and seed weights, estimates of the number of viable and nonviable seeds, average number of seeds per berry, proportion of viable seeds that germinated.

Provenance & quality
Berries were collection from 18 populations in 2015 then measured and processed by hand. Berries were stored at 4 deg C as necessary to keep them from moulding until they could be processed. Dry seeds were also stored at 4 deg C until they were sown for the germination trial. The germination trial was conducted at the greenhouse at the UKCEH Edinburgh, and seeds were sown in 1:1 mixture of sand and compost.
Seed trays were subjected to a warm stratification treatment (7-14 deg C) for four months, then a cool stratification (4 deg C) for 8 months before being placed in the glasshouse at the UKCEH, Edinburgh.
