Experimental design for magnesium (Mg), iron (Fe), calcium (Ca), potassium (K), and phosphate (P) deficiency in rice. Seedlings were grown hydroponically for two weeks. The plants were transferred to culture solutions with the target mineral omitted and were grown for nine days. At Day 9, the plants were resupplied with each mineral. The plants were observed at Day 12. The red-colored leaf position indicates a dead leaf. The leaf positions are defined in Figure 1c.
