From: Silicon and salicylic acid confer high-pH stress tolerance in tomato seedlings
Effects of alkaline stress on tomato plants. (A) Shoot length. (B) Shoot diameter (C). (D) Photograph of the shoot, illustrating the typical differences among all treatments at each pH. Tomato seedlings were grown in pots. A solution at pH 6.0 and pH 9.0, respectively, was applied daily to each pot. *,**, *** and **** indicate a significant difference between treatments at a given pH where P < 0.05, 0.01 and 0.001, respectively, and “ns” indicates non-significant differences. Different letter (s) indicate a significant difference (P < 0.05) among all treatments by DMRT test.
