Field-book for a germination assay with alfalfa
Description
The germination of alfalfa was assayed at 7 temperature levels, on three replicated Petri dishes per temperature and 100 seeds per Petri dish. Inspections were made in several times after the beginning of the assay.

Details
Every line of data represents a Petri dish. There were 100 seeds per Petri dish. The columns represent the characteristics of each Petri dish. The columns from 4 to 32 represent the number of germinated seeds counted at each assessment time.
