Fig 4. Influence of percentage of green light on shoot fresh mass, dry mass, and moisture content of lettuce ‘Cherokee’ and tomato ‘Bamborange’ with (+) and without (-) far-red light.

See Fig 1 and Table 1 for information on the lighting treatments. Each data point represents the mean and standard deviation of two replications with 10 subsamples (plants) per replication and species (n = 20). Regression equations, r² values, and P values are presented when statistically significant (solid line) but not when non-significant (dashed line).
