But a combination of TA and TSS, including the number of days
after fruit set (DAFS), (Wanitchang et al., 2011) was more consistent
with Fig. 1. Slight to moderate empirical linear correlations
(n = 11) were noticed between chlorophyll a and b (R2 = 0.93), TA
and TSS (R2 = 0.80), TA and chlorophyll b (R2 = 0.77), and TA and DM
(R2 =
−0.77).
