Figure 9

Pectin methylesterase (PME) activity and degree of methyl esterification of ‘Royal Gala’ and ‘Scifresh’ fruit cell walls during development. PME activity (A), degree of methyl esterification of cell wall material (B) and CDTA-soluble pectin (C). Fruitlet: 40 DAFB; Expanding fruit: 70 DAFB; Mature fruit: 120 DAFB (RG) 140 DAFB (SF); Ripe fruit: 20 weeks at 0.5°C. Values in (A) are the means of 3 assays ± standard deviation; values in (B) and (C) are the means of 6 assays ± standard deviation. Asterisks indicate significantly different values at a level of P ≤ 0.05 using a protected Fisher’s least significant difference test.
