The dataset consists of the age of each gravestone (the difference between the current year and the year the person died), the depth of degradation (in mm) as determined by the lettering alteration method, and the location of the gravestone where the value of location is 0 for coastal and 1 for inland. |

During the rooting period, all shoots were maintained under identical conditions but the shoots themselves were cultured on media containing different concentrations of cytokinin BAP, in growth cabinets with an 8 or 16 hour photoperiod. Thus each experimental condition is decribed by two factors: BAP concentration (2.2, 4.4, 8.8 and 17.6 $\mu M$) and photoperiod (8 and 16 hours). |
