Table VII.
Number of chloroplasts per cell, chloroplast size and pigment content (chlorophyll and total carotenoids) in fruit pericarp tissue of hp-2dg and hp-2j mutant plants and their normal controls
Measurements were carried out in mature-green fruits, except for total carotenoids assayed in pericarp tissue of ripe-red fruits; chloroplast size was measured as plan area; values are displayed as mean ± se; n = number of cells analyzed. Different superscript letters indicate statistically significant differences between means [P(F) < 0.001].
