Light filter experiment

The data file attached describes extrafloral nectar collected from Senna mexicana var. chapmanii plants in a greenhouse experiment conducted at Florida International University. The data set is made up of 12 columns described below. A. Plant number. Each plant used in the study has a designated number. B. Light treatment: C=clear film; S=shade film; R=shade film with increased far red/ red light ratio. C. Damage treatments: D=damage; C=no damage. D. Factorial treatment numbers: eg: 1= clear film + damage. E.F.G. Quantity of extrafloral nectar collected (E=µl; F=any additional portion of a µl tube filled with nectar; G=total nectar volume collected). H. Nectar concentration measured using a hand held refractometer. I. Sugar production calculated using volume and concentration data. J. Sugar mass (g)/µl K. Sugar mass(mg)/µl L. Total mass of sugar produced by each plant at each time of measurement
