Fold change of response to P treatments (log₂^[−P/+P]) in mean volume, surface area, length, average thickness, and tips of roots.

Parameter	Fengqing	Longjing-43
Volume	−1.54 *	−2.84 *
Surface area	−1.67 *	−1.99 *
Number of root tips	−1.96 *	−0.77 *
Length	2.32 *	0.49 *
Average thickness	0.15 *	0.01NS

NS and * indicates insignificant or significant ($p<$ 0.05) differences between the two P levels.
