Fig. 1 presents the effects of flooding time on the APX
activity of tomato and eggplant roots. The trend and rate
of the increase in APX activity over time were different
in the eggplants. APX activity in EG203 accumulated
at different rate from 0 h (34.29 mol g−1 fw) to 72 h
(184.05mol g−1 fw). APX activity in EG117 accumulated
from 0 h (47.53 mol g−1 fw) to 48 h (184.05 mol g−1
fw), and then dropped to 161.47 mol g−1 fw after 72 h
of flooding time. However, APX activity did not show
any significant difference for the tomatoes during the time
course of flooding. When entries across flooding time
were compared, EG117 exhibited a significantly higher
APX activity than L4422. It is noteworthy that EG117
(184.05mol g−1 fw) displayed a six-fold greater increase
than L4422 (29.32mol g−1 fw) by the 48 h flooding time
