Abstract
Low-chill peach production has increased in recent years.
However, the fruit is less acceptable to consumers than that of high-chill peaches because of its low fruit quality.
Hence, the production of high-quality fruit is essential for low-chill peaches.
In the present study, effect of girdling on fruit quality of low-chill, early ripening peach KU-PP2, bred at Kagawa University was evaluated.
The girdling treatment was applied at two, four, and six weeks (G1, G2, and G3, respectively) after full bloom on March 11, 2021. Girdling was conducted with a width of 2 cm in each treatment, except for the control.
We compared the effects of girdling on fruit growth, shoot growth, and fruit quality during 2021 ripening season.
All girdling treatments improved fruit quality parameters, such as fruit weight, size, total soluble solids (TSS) and red coloration.
Among all treatments, the G2 treatment improved fruit size and TSS the most.
The skin color, L*, a* and b*, was the highest in the control, G1 and G3 treatments, respectively.
In conclusion, we found that girdling treatments improved the quality of harvested fruits and that 4 weeks after full bloom was the optimal girdling time for low-chill early ripening peach KU-PP2.
