^† Values are means ± s.e. (n = 9) and differences between means were compared using Duncan's test (P = 0·05).

^‡ Values are means (n = 27) and differences between means were compared using LSD test (P = 0·05).

^§ Levels of significance are represented by *P < 0·05, **P < 0·01, ***P < 0·001 and ns (not significant, P > 0·05).
