Values are means ±SD (% of total lipids analysed; n = 4). Significant differences in the samples at 48 h and 96 h followed by light submergence treatment to that of controls are in bold. Control refers to samples harvested from untreated plants.

^aValues were higher when compared to controls in the same experiment (*P<0.05; **P<0.01).

^bValues were lower when compared to controls in the same experiment (*P<0.05; **P<0.01).
