Abstract:

To identify the optimal anti-cracking agents formulation for sweet cherry under protected early cultivation, taking the cultivar ‘Tieton’ as the test material, 7 treatment groups (T1-T7) involving different combinations of organic fluid calcium, water-soluble fertilizers (formerly Jugu shenfeng), gibberellic acid (GA3), and plant element-rich nutrient solution (formerly Haiyangsu) were set up, with water spray as the control (CK). The responses of fruit characteristics, cell wall materials, and enzyme activities to these foliar applications were investigated. The results showed that these treatments significantly increased the protopectin and cellulose content, thereby enhancing cell wall stability and further reducing the incidence of fruit cracking. However, the application concentration required careful consideration. The most effective treatment was a 300-fold dilution of water-soluble fertilizers combined with 30 mg/L GA3 (T4); the combined application of a 300-fold dilution of water-soluble fertilizers and a 100-fold dilution of plant element-rich nutrient solution (T5) resulted in the optimal overall fruit quality. Furthermore, the activities of superoxide dismutase (SOD) and catalase (CAT) in treated fruits were significantly higher than that in the control, while peroxidase (POD) activity was lower. This exogenous regulation was helpful to maintain the dynamic balance of the POD/SOD/CAT enzyme system, preserving cell wall plasticity and membrane integrity, which ultimately contributed to effective crack control. In addition, the application of either organic fluid calcium or water-soluble fertilizers increased the vitamin C content in the fruits, with the most pronounced effect observed when water-soluble fertilizers and plant element-rich nutrient solution were applied together. In conclusion, the results demonstrate that the combined application of GA3, plant element-rich nutrient solution, and water-soluble fertilizers effectively reduce the fruit-cracking rate of ‘Tieton’, and significantly improve the fruit quality, which provides scientific basis and practical guidance for the prevention and control of fruit cracking in facility early cultivation of sweet cherries..
