One of the pitfalls of this cultivar is the development of cracks on its surface. These cracks turn brown after astringency removal, preventing the commercialisation of this cultivar. Pre-harvest treatment with Superlon™ (containing benzyl adenine (BA) + gibberellic acid (GA4+7) at 40 mg/L of each) or Turbo™ (containing Thidiazuron (TDZ) at 5 mg/L) reduced cracks of different maturity fruit (green, green orange, and orange fruit) at harvest and following 5 days of astringency removal. Cracks remained low in the Plant growth regulators (PGRs)-treated fruit also following three months of storage. The PGRs treatments also reduced damage and Alternaria infection, developed during storage. Although fruit lost their firmness during storage, the PGRs-treated fruit remained firmer. Both PGRs treatments increased the number of cells in the peel. Thidiazuron was as effective as BA+GA4+7 treatment at eight times lower concentration of each of the compounds. Hence, in-orchard TDZ treatment can be used to reduce persimmon cracks.
