This study investigated the quality and antioxidative properties of a Korean steamed-rice cake, Sulgidduk added with Prunus yedoensis Matsumura extract, and vitamin C. Sulgidduk was prepared by adding Prunus yedoensis Matsumura extract at 0, 0.1, 0.2, and 0.3% of rice powder. Antioxidant activities were measured by the scavenging activities of DPPH radicals, $ABTS^+$ radicals, $superoxide^-$ radicals and the reducing power. For analyzing quality characteristics, proximate composition, color, texture profile analysis, and sensory evaluations were measured. The antioxidative effect of the Sulgidduk significantly increased as the addition level increased, compared to the original Sulgidduk (p<0.001). As the content of Prunus yedoensis Matsumura extracts increased, L-values significantly decreased while the a-value and b-value significantly increased (p<0.001). For the texture profile analysis, the control group had a significantly higher value for hardness as compared to the Prunus yedoensis Matsumura extract-added groups (p<0.05). Springiness, chewiness and adhesiveness were not significantly different among the samples. In the sensory evaluation, the samples containing 0.1% and 0.2% Prunus yedoensis Matsumura extracts obtained better results in attribute. From these results, we suggest that Prunus yedoensis Matsumura is a good ingredient for increasing the consumer acceptability and the functionality of Sulgidduk.

This study conducted to analyze the growth characteristics of old Prunus yedoensis on Jeju island. The diameter growth per year was measured using a DTRS-2000 instrument. The DBH, ground DBH and height of the investigated P. yedoensis were 137 cm, 143 cm, and 15.5 m, respectively. Our analysis showed that the age of the old P. yedoensis was 93 years. An annual diameter growth of $2.85mm{\pm}0.96$ was observed. The result of age estimation, about $265{\pm}64$ years in P. yedoensis on Jeju island. This information could be useful to understand the annual diameter growth characteristics the P. yedoensis distributed on Jeju island.

This study was carried out to find the suitable root-ball size for the planting construction of landscape trees. Surveyed trees for this study were Cercidiphyllum japonicum and Prunus yedoensis, and the root-ball size was classified into 3D, 4D, 5D, and 6D(D meaning the diameter at the base of a tree). Visual ratings on a scale of 1 to 9 were used as a means for measuring the regrowth strength after planting tested trees. Test trees with 3, 4, 5 and 6D root-ball size were planted on March. 16, 2002 and visual ratings were measured up to April. 30, 2003. Cercidiphyllum japonicum and Prunus yedoensis started showing a difference in regrowth by each rootball size a month after planting. The regrowth quality of Cercidiphyllum japonicum was low at 3D, medium at 4∼5D and high at 6D root-ball size, while the regrowth quality of Prunus yedoensis was low at 3∼4D and medium-high at 5∼6D root-ball size. According to the above results, a root-ball size for good regrowth quality was a little bit different between Cercidiphyllum japonicum and Prunus yedoensis. 4D of Cercidiphyllum japonicum and 5D of Prunus yedoensis could be guidelines for root-ball diameters at the base of trees when planting. However, we concluded that 4D∼5D root-ball is the optimum guideline for regrowth when adapting this guideline to all landscape trees with 8∼l0cm diameter at the base.

Since Taquet's first discovery of wild P. yedoensis at Mt. Halla, Korea, in 1908, its morphological chracteristics and question of origin of cultivated yedoensis have given controversies to the botanists. Takenaka, through his experiments on the hybridity of cultivated P. yedoensis, recently holds the opinion that P. yedoensis might have originated in Izu peninsula, Japan. The author presents the summarized report on the wild P. yedoensis and its putative parents based on his 2 years' investigated carried out at Mt. Halla during his breeding experiment of genus Prunus. The species of cherry tree used in the present investigation were identified by Prof. Mankyu Park and Mr. Jonghyu Pu, Korean taxonomists. 1) Wild cherry trees which grow wild in Mt. Halla and whose blooming season is April are mostly P. subhirtella var. pendula form. ascendens and P. donarium P. yedoensis is rare in number, around 10 individuals, having been found in a half century. 2) Individuals of wild yedoensis are variable in some of their morphological characteristics. This is, also, true in other species of Prunus. 3) Wild yedoensis whose vigorous growth, sterility, and rarity in number suggest hybrid origin, has intermediate characteristics between the P. subhirtella and P. donarium. 4) Due to the abnormal weather of the island and various environmental factors such as havbitats, some of the early-blooming subhirtella and late-blooming donarium would bloom at the same time, giving these two species the changes to cross. 5) Wild yedoensis is slightly different in some of its quantitative characters from cultivated species.

The origin of cultivated Prunus yedoensis Matsumura has been controvertial among botanists. This plant has been reported grown wild in Mt. Hanla. During the crossing experiment on the P. yedoensis and its putative parent performed from April 7 to 19 in Mt. Hanla, the writer studied morphological and physiological characteristics of various species of Prunus and assumed that the wild P. yedoensis may be a hybrid between P. subhirtella var. pendula form. ascendens and P. donarium.

Prunus × yedoensis is a representative tree species in residential areas often used as a street tree or park tree, with its popularity due to splendid flowers in the spring. We investigated plant growth, photosynthesis, chlorophyll, and carotenoid concentrations of Prunus yedoensis at 400ml/pot, 1,000ml/pot, and 2,000ml/pot Irrigation treatments. Overall growth indices such as tree height, diameter at root collar (DRC), and total dry weight could be ranked in the decreasing order "2,000ml/pot > 1,000ml/pot > 400ml/pot.". However, 2,000ml/pot featured decreased photosynthesis and total chlorophyll carotenoid contents than 1,000ml/pot treatment after July. And also, The 1,000ml/pot treatment showed relatively high photosynthetic activity and chlorophyll contents. These results suggested that the cultivation of Prunus yedoensis under 1,000ml/pot Irrigation treatment(soil water contents 25~35%) showed the best condition in growth.

Horizontal starch gel electrophoresis in three buffers was used to compare the electrophoretic patterns in three cherry species, wild Prunus subhirtella, cultivated P. yedoensis and P. donarium. Electrophoretic patterns of glutamate oxaloacetate, transaminase-2(GOT-2), malate dehydrogenase-2(MDH-2), and phosphoglucose isomerase(PGI) in three species showed strong evidence that P. yedoensis might be originated by hybridization between P. subhirtella and P. donarium.

우리나라의 가로수 중 왕벚나무와 쥐똥나무를 공시하여 SO$_2$의 처리농도를 달리했을 때 각 수준에 의한 수피산도, 엽중산도 및 엽내 수용성 황 함량의 변화를 측정하여 SO$_2$가 수목에 미치는 영향을 분석한 결과는 다음과 같다. 왕벚나무와 쥐똥나무의 각 농도별 수피산도는 전체적으로 SO$_2$의 농도가 높아질수록 pH는 낮아지는 경향을 보였으며, SO$_2$ 농도별 처리에 따른 수피산도 증가율 변화에 있어서는 왕벚나무가 큰 폭의 증가율을 보였고, 4.0 ppm의 농도로 처리하였을 때 쥐똥나무에 비해 수피산도에 대한 상대적 감수성이 큰 것으로 사료된다. 농도별 엽중산도는 수피산도와 마찬가지로 전체적으로 SO$_2$의 농도가 높아질수록 엽중산도는 높아지는 경향을 보였으며, 대조구의 경우 공시목의 엽내 수용성황 함량 분석결과는 쥐똥나무(0.0105%)가 왕벚나무(0.0056%)보다 높게 나타났으며, 공시목 2개 수종 모두 SO$_2$ 가스 농도가 높아짐에 따라 엽내 수용성 황 함량이 증가하였다.

In vitro organogenesis system of the valuable ornamental species, Prunus yedoensis which is native to Korea, was established through callus culture derived from root tissues. Callus were induced on the medium supplemented with 2,4-D and BA or NAA and kinetin. Organogenesis was differ from the callus type, and NAA and kinetin combination was effective to induce organogenic callus. Growth of callus was influenced by sucrose concentrations. High level of sucrose (over 5%) had adverse effects such as decreased fresh weight and increased mortality of callus. Shoots developed from the callus when $GA_3$ was treated with BA in the medium. Results showed that $GA_3$ is essential for shoot development and elongation from callus in this species.
