From: IAA was involved in phosphorus deficiency-induced cluster roots formation in Macadamia integrifolia
Changes in cluster roots number of macadamia upon addition of IAA/NPA. Plants grown in 5 µM P and 100 µM P nutrient solutions were treated with 5 × 10− 6 mol/L IAA/NPA for 4 months. Different lowercase letters mean a significant difference among different treatments (P < 0.05).
