Dynamic changes of grape fruit size and contents in different growth stages. (A) Dynamic change of single fruit weight in different growth stages. (B) Dynamic change of fruit width in different growth stages. (C) Dynamic change of fruit vertical diameter in different growth stages. (D) Dynamic change of soluble solids in different growth stages. (E) Dynamic change of titratable acid (TA) content in different growth stages. (F) Dynamic change of total soluble solid/TA (TSS/TA) in different growth stages. (G) Dynamic change of pH in different growth stages. (H) Dynamic change of anthocyanin content in different growth stages. RR: Root restriction, CK: control group. 1–9 indicate that the sample collection time is 6 June, 14 June, 22 June, 4 July, 14 July, 18 July, 23 July, 1 August, and 9 August 2017, respectively. * p < 0.05 and ** p < 0.01 respectively according to two-tailed Student’s t-test. Error bars show the standard error between three biological replicates (n = 3).
