Title 1. Development of technology for tree form of ‘Arisoo’ apple cultivar according to the planting density
□ Purpose&Contents
Study of different pruning effects on fruit quality of ‘Arisoo’ apple cultivar
□ Results
< Pruning management of lateral branches of ‘Arisoo’ cultivar in the second year after planting >
In the 1/2 heading-back pruned trees, the average number of main branches was 9.2 with the growth of 36.2 cm, while the main branch number was 10.8 with 39.7 cm growth in the trees treated with a downward bending. Therefore, to construct the early tree form, it is
< The annual growth characteristics of ‘Arisoo’ cultivar according to the planting density >
Growth characteristics: In the second year after planting, tree showed the least growth at 3.5 × 1.0 m planting density. In the third year after planting, tree shape was complex and the minimum overlapped tree width were 50 cm at 3.5 × 1.0 m, 33cm at 3.5 × 1.5 m, and 8cm at 4.0 × 2.0 m.
In the fourth year after planting, tree width was 190 cm at 3.5 × 1.0 m and more than 50 cm of tree shape was overlapped. The growth of new shoots was gradually decreased compared to the previous year as the tree vigor is stabilized and the fruit load is increased as well.
Fruit yield: In the third year after planting, the amount of fruit load per tree was the largest at 4.0 × 2.0 m, while there was no difference in the averaged fruit weight among planting density group. The fruit yield was 8.4 kg per tree at 4.0 × 2.0 m spacing and 6.2 kg per tree at 3.5 × 1.0 m spacing. In 3.5 × 1.0 m planting density, the area yield (kg/10a) was the largest.
In the fourth year after planting, there were no differences in fruit load,fruit weight, and fruit yield (kg/tree) among group, but the area yield(kg/10a) was the largest at 3.5 × 1.0 m spacing.
< Pruning management of mid-section scaffolds in ‘Arisoo cultivar >
From the fourth year after planting, the mid-section scaffolds at 1.5~2.5m height were cut with a heading-back pruning from 1/2 and 1/3 position and the lateral branches were treated with a bending rather than a pruning.
The light penetration rate was the lowest in the bending treatment of lateral branches at 1 m height of the tree and the highest in the 1/3 position heading-back pruning treated trees.
In the distribution of fruit weight, the percentage of over 300 g weighted fruit was the highest in the 1/3 position heading-back pruned trees, while medium-sized fruit (200 ~ 250 g) distribution was largest in the trees with mid-scaffold bending treatment rather than pruning.
□ Expected Contribution
Maximizing efficiency of farmers' supply by developing sustainable vigor maintenance technique of Hongo varieties

(Title 2) Research on optimum crop load in young ‘Arisoo’ apple tree
□ Purpose&Contents
This study was conducted to promote dissemination of domestic‘Arisoo’ apple with establishment of cultivation techniques regarding proper crop load in young tree and suitable bearing shoot for high-quality fruit.
□ Results
-The optimal crop load of ‘Arisoo’ is 3 fruit/㎠ trunk cross-sectional area(TCA) in 3th and 4rd leafy year
-Bearing shoot length ranged from 15.1㎝ to 20.0㎝ is advantageous to produce larger apple
□ Expected Contribution
- Contribution to early tree vigor control and stable production by appling fruiting guideline for ‘Arisoo’ variety.
- Increase income of 'Arisoo' growers by adopting high-quality fruit production technique.
- Expansion of domestic apple varieties by providing cultivation practices suitable for 'Arisoo'.

Title 3. Study of nutrition assessment and standard fertilization of 'Arisoo' young apple tree
□ Purpose&Contents
This study was performed to establish both a proper nutritional assessment and an amount of standard fertilization level of a new‘Arisoo’ apple cultivar to provide a minimum cultivation guideline in apple orchards.
□ Results
1. Nitrogen nutrition assessment
A significant positive correlation between the chlorophyll meter(SPAD-502; Konica Minolta Sensing Inc., Sakai, Japan) and leaf nitrogen (N) content was established throughout the growing season.
The best time for predicting foliar N content in ‘Arisoo’ apple tree was late June according to the regression analysis. The linear regression model in June was ŷ= -4.012+1.178x, ŷ=ln(N),x=ln(SPAD). To conduct nutrition assessment, at least 10 leaves need to be sampled from the 4th to 10th position of new shoots in June.
2. Standard fertilization level
To estimate annual nutrient uptake of a apple tree, nutrient profile data were combined with dry matter from total 9 different tissues and 3 major elements (N, P, K) were further used in analyzing optimum nutrient uptake capacity. 8.20g, 14.47g, 32.75g of N were absorbed in a ‘Arisoo’/M.9 tree each year after being planted. P (0.03g, 0.29, 1.38) and K (0.01, 0.03, 0.04) were absorbed respectively. Nutrient uptake capacity of N, P, K was calculated with unit conversion into area (kg/10a). To sum up, The standard fertilization amount for ‘Arisoo’ young apple orchards was N 1.191, P 0.048, K 0.003 in the first year of planting, N 3.473, P 0.208, K 0.006 in the second year. On the other hand, the effect of orchard conditions such as soil fertility and tree vigor should be considered to determine the actual field application level in the orchard.
□ Expected Contribution
Our results suggest for ‘Arisoo’ orchard farmers to determine the standard fertilization level for the young ‘Arisoo’ trees. A fast, nondestructive nitrogen nutrition assessment can also support a reliable nutrition management in the ‘Arisoo’ orchards.

Title 4. nvestigation of storability, fruit Quality and Preharvest Drop During Maturation of ‘Arisu’ apples
□ Purpose&Contents
To spread the cultivation of arisoo apple, the purpose of this study was to investigate the fruit quality during maturity and storability
□ Results
Storability of Arisoo apple in cold storage is 60 days and safe storage period of ambient temperature storage is 20 days. It is effective to spray 0.3% of calcium chloride four times at the intervals of 7 days from the beginning of June for prevention of the preharvest drop of the Arisoo cultivars
□ Expected Contribution
- Use as varietal selection data of Arisoo apple
- It contributes to increase of the farm’s income

Title 5. A Study on the incidence and dissociation of disease and insect on the ‘Arisoo’ apple
□ Purpose&Contents
In order to utilize 'Arisoo' apple as a basic data for pest control, we investigated and analyzed the occurrence characteristics of pests occurring in 'Arisoo'.
□ Results
When the specificity of the occurrence of the pests of 'arisoo' apples was analyzed, occurrence of the Cedar apple scab,(Gymnosporangium yamadae) Alternaria mali, and Marssonina coronariai were less than that of cultivar 'Hongro'. Bitter rot and White rot were scarcely occurred, and overall it was judged to be resistant to disease as compared with 'Hongro', a control cultivar. The insect species were Phyllonorycter ringoniella, Lyonetia prunifoliella, Grapholita molesta, Plautia stal, and Halyomorpha halys. In particular, guidelines were established to distinguish the damage pattern of Halyomorpha halys and the abnormal symptoms of fruit. The resistance of the ‘Arisoo’ varieties to crown white rot was moderate, That of ‘Arisoo’ to Valsa mali was differentely investigated.
□ Expected Contribution
Use as basic data for apple pest control
