Figure 6.

Electrolyte leakage index of quinoa plants in a Hoagland solution (Hoagland and Arnon²³) under omission of macronutrients in the absence (− Si) and presence of silicon (+ Si). Equal lowercase letters demonstrate a similarity between the omitted and complete treatments by Tukey’s test at 5% probability. Equal uppercase letters show a similarity between treatments (− Si and + Si) by Tukey’s test at 5% probability.
