Phenomics Stems

Description

A dataset containing phenotypic variables measured on floral stems of five A. thaliana genotypes at two growth temperatures. See Ecotype and Temperature for more information.

Usage

data("Phenomics_Stems")

Format

A data frame with 30 rows and 4 variables:

• Mass: floral stems mass (g)

• Diameter: floral stems diameter (mm)

• Length: length of the floral stems (cm)

• Number_lateral_stems: number of lateral stems)
