Details

In the data set, there are four variables: code, species, time and height. code is used to save the number codes of different bamboo species; species is used to save the Latin names of different bamboo species; time is used to save the observation times (d) from a specific starting time of growth, and every bamboo has a different starting time of growth; height is used to save the measured aboveground height values (cm).

code = 1 represents Phyllostachys iridescens, and the starting time (namely time = 0) was defined as 12:00, 3rd April, 2016;

code = 2 represents Phyllostachys mannii, and the starting time (namely time = 0) was defined as 12:00, 4th April, 2016;

code = 3 represents Sinobambusa tootsik, and the starting time (namely time = 0) was defined as 12:00, 18th April, 2016;

code = 4 represents Pleioblastus maculatus, and the starting time (namely time = 0) was defined as 12:00, 29th April, 2016.
