Soil redox potential for green buttonwood during the first, second and final flood periods ranged from +193 mV to +162 mV, +597 mV to +166 mV and +508 mV to +153 mV, respectively.
However, there were no significant differences between infested and non-infested green buttonwood plants for A or [g.
There were no significant effects of flooding or larval infestation on stem diameter or plant height for either green buttonwood or Swingle citrumelo (data not shown).
For green buttonwood, there were no significant effects of flooding on percent larval survival or head capsule width of recovered larvae (Table 2).
In addition, for both plant species, during all 3 flood cycles (except for green buttonwood flood cycle 1), the highest redox potential occurred on day 1 (when flooded) and the lowest was on day 3 (when drained).
Based on leaf gas exchange and plant growth in the present study, green buttonwood was more susceptible to flooding than Swingle citrumelo.
abbreviatus larval survival rates on green buttonwood in flooded marl soil than in non-flooded marl soil and in flooded potting medium than in non-flooded potting medium.
abbreviatus has been shown to reduce leaf gas exchange and growth in several woody ornamental plant species including green buttonwood (Diaz 2005; Diaz et al.
abbreviatus larvae infestations on green buttonwood, and flooding was recommended by Li et al.
Overall, decreases in leaf gas exchange and plant dry weight observed by Diaz (2005) were attributed more to flooding than to larval infestation in green buttonwood.
However for green buttonwood plants, flooding seemed to have no effect on larval growth, survival, or insect damage.
