Fig. 1 – Time course of Gamma-aminobutyric acid (GABA) content at different soaking temperature (Ts) and germination
temperature (Tg) for two rice cultivars (A: indica Guichao 2; B: japonica Jing 305). The three lines in both A and B were
selected from the high, moderate and low GABA content according to the range of soaking and germinating temperatures.
Neutral water was used for soaking the seeds.
