Phosphate/Zinc Interaction Analysis in Two Lettuce Varieties Reveals Contrasting Effects on Biomass, Photosynthesis, and Dynamics of Pi Transport
Figure 3
Correlation between zinc and inorganic phosphate in Paris Island Cos and Kordaat. Zinc and inorganic phosphate contents were determined in shoots and roots of the two lettuce varieties (◯, Kordaat; ◆ Paris Island Cos) grown in the presence of 500 M of Pi and changing Zn concentrations (0, 15, 90, 360, 1440, or 2880 M). Correlation between Pi content in shoots and Pi content in roots (a). Correlation between Zn content in shoots and roots (b) Correlation between Zn content in shoots and Pi content in roots (c). Correlation between Zn content in shoots and Pi content in shoots (d). Lines correspond to linear regression. For each regression, the square of Pearson’s correlation coefficient () is reported.
