Note: A, the data shown are the means±standard deviations (SDs) (n = 3). * indicates a significance level of P<0.05 between two pummelo fruits. B, the data shown are the means±SEs (n = 3). ABA: abscisic acid. DPA: days postanthesis. IAA: indole-3-acetic acid; JA: jasmonic acid; SA: salicylic acid. a, b above the columns indicate significant differences at the P<0.05 level. SM: segment membrane. JS: juice sacs.
