Table 2.

Sterol content (μg mg^− 1 of protein) of plasma membrane from cauliflower inflorescences and leaves at 70 days and 90 days of plant development. The data are represented as the means (n = 3, where n = different plasma membrane extractions) ± SE. Different letters indicate statistically significant differences (p < 0.05, HSD Tukey’s test) between treatments
