Table VI. Enzymatic activities in breaker fruits in the ME lines.

Values are presented as means ± se of six biological determinations. Values that are significantly different by Student’s t test from the wild type are set in boldface (P < 0.05). Vsel, Absence of dithiothreitol; Vred, presence of dithiothreitol.
