Data from POP369 were collected in two successive years (2011 and 2012) while POP356 was analysed in 2011 only. N.B.: comp_417.12 (1) and comp_417.12 (2) are unknown compounds identified from LC-MS quantification analysis, represented by their molecular weight. Units for trait studied are following: FD (scale), TSS (°Brix), Firmness (N: newton), PPO (change in A₄₂₀/ g/minute), AsA and polyphenols compounds (concentration). comp_417.12 (1) and comp_417.12 (2) are unknown polyphenol compounds identified from LC-MS quantification analysis, represented by their molecular weight.
Note: * = P < 0.05 ** = P < 0.01 and ^ns = non-significant.
