R&D
Research on the production of high quality sweet persimmon
- Breeding of new cultivars with early maturity and high quality
- Establishment of cultural technology for saving of labor and production of high quality fruit
- Postharvest technology for fruit freshness during storage
Performance
1. Research on enhancement of productivity and quality of sweet persimmon
- How to store the persimmon seeds to be used as rootstock : germination increased by 2.4 times from 33.6 to 81.3% / PE bag in 5°C
- Research on the early fruit bearing technology in young tree by topping as summer pruning : yield increased 13.6 times from 34.4 to 466.4 kg/10a in next year.
- Effect of bud-thinning and fruit-thinning in mid-May and late-July respectively on the fruit quality : fruit weight increased by 9% and income was enhanced by 50%
- Applied for the trademark for Internet sweet persimmon snack
2. Increasing the value by increasing the storage capability
- Improved the packing method to maintain the freshness of sweet persimmon for exports: increased the hardness of the products by 2.1 times
- Packing method of sweet persimmon for exports to keep the freshness : Precooling down to 2-5°C for 1 - 2 days, heating adhesion, sealed with ethylene gas absorbers
- Connection method between packing paper and support with PE film heating adhesion, which is registered as new design
3. Breeding for high quality sweet persimmon with early- or medium-maturity
- 3 projects including crossbreeding
4. Early harvesting technology
- water permeating prevention technology, pruning method and pruning during summer
