| Resumo: |
Flesh softening, skin browning and rotting are chief problems during cold storage (CS) of 'Fuyu' Persimmon. We studied the effects of boron (B) and calcium (Ca) sprayed on the trees during three consecutive years, on the development of skin cracks, grooves and browning in persimmon fruit under CS in Farroupilha, RS, Brazil (29°31' south, 51°21' west, about 750 m altitude). A homogeneous orchard area of 0.5 ha was delimitated and three sets of five plants for each treatment were randomly selected. The persimmon trees were sprayed at a 20 day interval, from 15th January until harvest, for three consecutive years, with: T1) water; T2) calcium nitrate at 0.5% (m/v); T3) calcium chloride at 0.5% (m/v); and T4) boron at 0.3% (m/v). The fruit were harvest with orange-reddish colour; 18-20°Brix, pulp firmness of 45 to 60N, and kept under CS at 0±1°C for 45 days. The fruits were evaluated immediately before CS, after six hours at 23±2°C after removal from CS, and after four days at 23±2°C after removal from CS. Equally boron and calcium sprayed on the trees prevented skin cracks, skin grooves and skin browning. Besides, when boron was sprayed on the trees, the mentioned effects were additive in the following year.
