Pseudomonas putida PG-9: Boosting Apple Yield and Quality

Translation: The effect of Pseudomonas putida PG-9 on apple yield and quality

Impact on apple yield The effect of Pseudomonas putida PG-9 on apple fruit yield is shown in Table 3. In 2021 and 2022, the average fruit weight of the PG-9-treated plants was 234.53g and 225.6g, respectively, which was an increase of 7.82% and 7.10% compared to the control group, and the difference was significant (P<0.05). In 2022, the average fruit weight of the PG-9-treated plants was 225.36g, an increase of 7.1% compared to the control group. In 2021 and 2022, the apple yield of the PG-9-treated plants was 64.90 t·hm-2 and 64.16 t·hm-2, respectively, which was an increase of 9.28% and 8.42% compared to the control group, and the difference was significant.

By analyzing the fruit diameter and the proportion of fruits in each category, it was found that in 2021, the proportion of fruits with a diameter between 75≤d≤85 mm was the highest in the PG-9-treated plants, an increase of 38.54% compared to the control group. The proportion of fruits with a diameter greater than 85 mm was also increased by 13.67% compared to the control group. In 2022, the proportion of fruits with a diameter between 75≤d≤85 mm was the highest in the treated plants, an increase of 3.28% compared to the control group. The proportion of fruits with a diameter greater than 85 mm was increased by 275.92% compared to the control group, and the difference between the treated group and the control group was significant (P<0.05).

These results indicate that the application of Pseudomonas putida PG-9 fermentation solution can significantly increase fruit size, promote fruit growth, and significantly increase yield and improve the quality of the fruit.
