From: IAA was involved in phosphorus deficiency-induced cluster roots formation in Macadamia integrifolia
Partitioning of dry matter (A) and root/shoot ratio (B) of Macadamia integrifolia grown with different rates of phosphorus (P) supply. Plants were grown for four months at 0, 5, 25, 50, 100 and 200 μM P. Different lowercase or uppercase letters mean a significant difference among plants growth under different P supplies (P<0.05).
