| Popis: | In this experiment, Qingcui plum in Xuanhan County of Dazhou City was used as the material. Aiming at the problem of fruit cracking, the cracking rate of different prevention measures was investigated by surface mulching, root irrigation, and foliar spraying of three different Ca fertilizers. The cell growth rate and cell wall composition were determined. The results showed that surface mulching and foliar spraying had significant effects on reducing fruit cracking rate; root irrigation greatly aggravating fruit cracking; the effect of foliar spraying calcium glycol was significantly better than that of foliar spraying calcium nitrate and calcium amino acid. During the second rapid fruit expansion period, the growth rate of pulp cells was always higher than that of pericarp cells, the pectin content of the fruit showed a downward trend, and the pectin content of the cracked fruit was significantly lower than that of the normal fruit; the cellulose content of the cracked fruit was significantly lower than that of the normal fruit. Therefore, the fruit cracking may be caused by the uncoordinated growth of pulp and peel, and the lack of pectin and cellulose. |
