Begonia Pot Plant Quality Scores
Begonia pot plant quality scores (for 2 varieties and 3 transport chains), during 5 weeks in simulated shelf-life conditions (temperature, light and irrigation). Quality scores were originally made on an ordinal scale from 1 to 10 (highest quality). However, only categories 2 to 9 were used, so these were re-coded to scale from 1 to 8. In addition to overall quality scores, a range of plant physiological characteristics were also observed.
A data frame with 720 observations on the following variables.

location in growing compartment; 1 to 48.
week number in simulated shelf-life; 1 to 5.
temperature in compartment;
light level in compartment;
irrigation in compartment;
quality score; 1 to 8.
count of dropped flowers.
count of dropped coloured buds.
count of dropped green buds.
count of damaged flowers.
count of single flowers.
count of double flowers.
count of yellow leaves.
