Table 1.
Model comparison results for repeated measures analysis of height, SPAD, Anet, and gsw for each of the four species (*: marginally significant, **: statistically significant).
Fig 1.
Effects of week and copper treatment on Anet of A) mustard greens, B) kale, C) beets, and D) turnips.
Points show mean ± 1 SE. Letters denote significant differences within weeks when a treatment x interaction was significant.
Fig 2.
Effects of week and copper treatment on gsw of A) mustard greens, B) kale, C) beets, and D) turnips.
Points show mean ± 1 SE. Letters denote significant differences within weeks when a treatment x interaction was significant.
