  • This experiment was conducted to investigate the propagation system by seed to check growth, flowering, and making seed of four-year-old seedling cactus of potted Astrophytum asterias 'Nudum', A. asterias 'Super Kabuto', and A. myriostigma 'Nudum'. Plant height and width of Astrophytum asterias 'Nudum' and A. asterias 'Super Kabuto' was 5.3 to 5.5 cm, and 2.5 cm. However, plant height and width of A. myriostigma 'Nudum' was 7.6 cm and 5.6 cm as divided into 8 sections of body. In A. asterias 'Nudum', the mean seeded pod from April to September was 37.0% and the number of seeds in a pod was 43.0. In A. asterias 'Super Kabuto', the mean seeded pod from April to September was 22.5% and the number of seeds in a pod was 26.2. However, the mean seeded pod of A. myriostigma 'Nudum' from April to September was 32.3% and the number of seeds in a pod was 57.4. Especially, the seeded pod and the number of seeds in a pod of A. asterias 'Nudum' in July was the highest, 72.0% and 66.0. The sib crossing obtained much more seeded pods and the number of seeds per pod than that of selfing in the Astrophytum. The self crossing was formed from 9.0 to 20.0% of seeded pod, and 12.0 to 16.0 seeds in a pod. However, sib crossing was formed 60.0% seeded pod and 68.0 seeds in a pod on July of A. myriostigma 'Nudum'.

  • Chrysanthemum plants are one of the most economically important plants in South Korea. Both virus and viroid can cause diseases and economic damage to the plants. In this study, we investigated the detection of seven viruses and two viroids in 350 chrysanthemum plants cultivated in Yesan-gun, Chungcheongnam-do. Two viruses, chrysanthemum virus B (CVB) and tomato aspermy virus (TAV), and two viroids, chrysanthemum chlorotic mottle viroid (CChMVd) and chrysanthemum stunt viroid (CSVd), were detected in this study. The two viruses were detected in six samples and one sample, respectively. The two viroids were detected in 97 samples and 21 samples, respectively. The nucleotide sequences of the CVB-CN-Y, TAV-CN-Y, CChMVd-CN-Y, and CSVd-CN-Y obtained in this study showed 83.7-86.9%, 99.2-100.0%, 94.4-99.5%, and 95.7-99.7% identity, respectively, compared to their other strains/isolates. The CVB-CN-Y and TAV-CN-Y showed the greatest nucleotide sequence homology to CVB-GS1 and three TAV isolates (TAV-V, TAV-P, and TAV-ChJ), respectively. The CChMVd-CN-Y and CSVd-CN-Y showed the greatest nucleotide sequence homology to CChMVd-Horst and four CSVd isolates (Au1.1, K4pop, Sagae, and Tochigi), respectively. This study is the report on the infection rate of viruses and viroids in chrysanthemum plants cultivated in Yesan-gun in 2021.

  • Agricultural environment of Lam Dong province, which is located in central highland area, is totally different from that of other lower areas in Vietnam. In Lam Dong province, abundant plant resources were naturally grown such as pine trees, taxus, and wild orchids, which can grow in high mountainous area. In Lam Dong, the field proportion of perennial crops was higher than that of annual crops. However, the field proportion and yields of vegetables were highest among the all cultivated crops, estimating 38% (36,552ha) and 72% (993,082MT), respectively. Especially in Da Lat, vegetables, flowers, orchids, and industrial crops were mainly produced because this area is geographically close to Ho Chi Minh city. And also in Da Lat, 64% (8,447ha) and 36% (4,777ha) of farm fields were used for producing annual and perennial crops, respectively, and the yields of fresh vegetables in this area was estimated to 213,478MT which was 21.5% of the whole yields in Lam Dong province. Thus Korea, Taiwan, Japan, France, and Holland have invested to agriculture in Da Lat for producing and exporting flowers, vegetables, and tea. In 2009, flower cultivation area of Da Lat was over 55% in Lam Dong province and average amount of values were 9,781 million USD, which was higher than that of al other crops. Thus following strategies could be suggested for the development of agriculture in Lam Dong province. The first, agricultural cooperation with Da Lat, Lam Dong, should be characterized to horticulture and floriculture, followed by supporting both appropriate R&D techniques and equipments. And then agricultural system should be made in relationship with the local companies. Finally, agricultural cooperation program should be conducted toward the direction for both donor and recipient countries.

  • The objective of study was carried out to find a proper entrance date for breaking dormancy depending on cutting and entrance date into greenhouse investigating plant growth and flowering characteristics of chrysanthemum 'Baekma'. Days to visible bud formation and days to flowering were increased as cutting date was delayed. The flowering rate of cutting on September 18 was 100% while cutting on October 30 did not induce flower bud formation. Flower characteristics were surveyed after 'Baekma' and 'Jinba' rooted cuttings were planted on September 10. Branching formation rate of 'Baekma' was gradually increased as entrance date was delayed while that of 'Jinba' was about 70-80% regardless of entrance date. Lethality of 'Baekma' moving into greenhouse on December 20 was 1.5% by cold injury. 'Jinba' started to die on November 10 by cold injury and lethality of 'Jinba' moving into greenhouse on December 20 was 21.7%. Thus, lethality of 'Jinba' was about 5-14 times higher than that of 'Baekma'. Days to visible bud formation and days to flowering were decreased as entrance date was delayed in chrysanthemum 'Baekma'. Days to visible bud formation of entrance date on November 10 and December 10 were 67.9 and 50.3, respectively. On the other hand, that of 'Jinba' was increased until entrance date on December 10 and decreased on December 20. Based on these results, it was suggested that dormancy of 'Baekma' was started at late September and completed at late October.

  • 'Duo', a late-flowering white gladiolus with pink core, was released by the National Institute of Horticultural & Herbal Science (NIHHS) in 2000. The selection was derived from the cross between the progenies of the early flowering dark pink 'True Love' and bright pink domestic cultivars 'Madame Valdiek'. The breeding was conducted in 1996 and selected finally in 2000 after four years (1997 to 2000) of experimentation. 'Duo' is a cut flower with bright white color petals and Pink core which exhibited late flowering and vigor without stem bending. It can be cultivated in areas or regions with strong winds during summer. 'Duo' has a very firm growth form and sturdy branches which do not bend when planted in the open fields. Likewise, the plant showed high tolerance to flooding and resistance, hence, could grow vigorously in open areas. It is a fast- growing plant which exhibits high corm production rate. 'Duo' had a 12.2 cm wide flower and 150 cm plant height. During summer, the average number of days to flowering was recorded at 75 days of 'Duo'. Top dressing must be conducted once or twice during corm production to enhance corm quality and quantity.

  • This study aimed to determine of water quantity in pot for water flooding culture of Pinus thunbergii Parl., Chaenomeles japonica Lindl. ex Spach and Osmanthus fragrans Lour. The survival rate of P. thunbergii Parl. and C. japonica Lindl. ex Spach in the water quantity in pot 60% or 40% was 100% and the rate of O. fragrans Lour. in the 60% or 40% water was 90.0% or 93.3%. However the survival rate of the 100% water was less than 90% in P. thunbergii Parl, C. japonica Lindl. ex Spach and less than 60% was in O. fragrans Lour. The increasing rate of plant height for P. thunbergii Parl. in the water quantity in pot 40% or 60% was above 50%, and the C. japonica Lindl. ex Spach or O. fragrans Lour. was above 90%. However the increasing rate of plant height in the water 100% was less then the others as a 38.2%, 65.4% or 66.7% in respectively in P. thunbergii Parl., C. japonica Lindl. ex Spach and O. fragrans Lour. The increasing rate for leaf number for P. thunbergii Parl. in the water quantity 40% or 60% was above 80%, and the C. japonica Lindl. ex Spach or O. fragrans Lour. was above 70%, however the 100% water was below 60% in all treatment. Therefore, the survival rates in some woody plants of the 40% or 60% water in the pot was above 90% and the plant growth of plant height, plant width, leaf number or fresh weight was proper increased. But the survival rates and growth of the 100% water in the pot was decreased

  • This study aims to investigate what flowering plant Jeongjo loved, the attitudes and the reasons, and their implications. The study method was to investigate the contents and meaning in the historical records and to describe their interpretation. Jeongjo's life was consistent with very abstinent life style. His food, clothing and shelter were simple, and he did not show the interests in music, various arts and craft, women, and so on. He did not even show his interest in the flowers and plants of fairyland, beautiful flowers and plants. Jeongjo knew various kinds of flowers, and he was proficient in artistic expressions such as literature or painting with flower material. Due to this kind of attitude, there were few cases to demonstrate his taste on the specific flowering plant. The only one that Jeongjo revealed as his favorite flower was the pomegranate. However, the pomegranate was not the simple flowering plant as the subject of enjoying to Jeongjo. The pomegranate has the meaning of indicator plant to indicate the season of rice farming. Therefore, he made it to be the intermediary to indicate the farming season, which counted a few. Besides, Jeongjo who was threatened by the trials of assassination to him in his early throne period utilized 5,600 pomegranate flowerpots as the barricade of his shelter by arraying them with the type of stone piles in $B{\bar{a}}zh{\grave{e}}nt{\acute{u}}$(八陣圖). The use of Jeongjo's pomegranate flowerpots was not related to the visual utilization like ornament at all, which was very unique case. From multiple records, it was found that the pomegranate was the flower to be with Jeongjo in his period of reign. It is remarkable that the reason why Jeongjo kept pomegranate for a long time like this had the difference from enjoying practice on the ordinary flowering plant. This study has the limitation to be conducted depending on the Korean translated data. Further studies are required according to the translation performance of new historical records.
