Table II. Wax composition of the fruit cuticles from wild-type and gpat6-a mutant plants.

Mean values (µg cm⁻² × 10) of each compound are given with sd (n = 3). The percentage of total wax load is indicated for individual compounds. Unidentified compounds are not included. Letters indicate significant differences from the wild-type composition (Student’s t test: b, P < 0.05; and a, P < 0.01).
