Figure 6.
Polyuronide elution profiles after size exclusion chromatography of the water soluble (WS), CDTA- and Na2CO3-soluble cell wall extracts of Actinidia chinensis var. chinensis ‘AC-F’ (A, C, E) and ‘AC-S’ (B, D, F) at the unripe, firm stage FC1 (black lines) and at the soft stage FC4 (red dotted lines). Higher molecular weight peaks are to the left, while lower molecular weight peaks are to the right. FC, firmness category. 2,000 kDa and 40 kDa refer to elution of the molecular weight standards used. Samples (extracted from CWM of ‘season 1’ and ‘season 2’) were eluted on a Superose 6, 10/300 GL column.
