Effects of Pi deficiency for 7 days on N22 RSA. N22 seedlings (4-days-old) were grown under P+ and P- conditions for 7 days. (A) Harvested roots were spread to reveal the details of RSA of P+ and P- seedlings showing (a) adventitious roots, (b) seminal and (c) primary roots along with their lateral roots. Data are presented for primary root length (B), number (C), and total length (D) of 1st order lateral roots on primary root, number (E) and total length (F) of 2nd order lateral roots on primary root, number (G) and total length (H) of seminal roots, number (I) and total length (J) of lateral roots on seminal roots, number (K) and total length (L) of adventitious roots, number (M) and total length (N) of lateral roots on adventitious roots, and total root length (O). Values (B–O) are mean ± SE and n = 12 replicates. Different letters on the histogram indicate that the means differ significantly (P < 0.05).
