Argyreia gyrobracteata Traiperm & Chitchak (Convolvulaceae) is newly recorded in Vietnam. It is similar to A. mekongensis Gagnep & Courch in having a white campanulate corolla but differs from that species by having whitish surface of the abaxial leaf, narrowly lanceolate or linear-oblong, curly, rolled up the bract with a longer length of the petiole and a shorter pedicel. It was previously known only in Thailand, but was recently found in Lam Dong Province, Vietnam, for the first time. The present study provides a detailed description, colorful photos and the distribution of the species. Furthermore, a comparison of the diagnostic characters between this species and a related species in Vietnam, A. mekongensis Gagnep & Courch, is provided.

This paper is on the reproduction of kwanmo, which is worn by the dancers in Taepyeongjiak at the National Classical Music Institute, focusing on Jinhyunkwan, Pybyun, Buyongkwan. Taepyeongjiak is a performance of the court banquet called Hoeryeyeon held during the 15th year of Sejong'reign(1433). The Hoeryeyeon performances were held on January 1st and December 22nd, to strengthen the good relationship between the King and his officials. The reproduction of kwanmo worn by the dancers was reproduced for the modern performances on the basis of the literature and relic research. The results of the study are as follows. Jinhyunkwan is the kwanmo that is associated with the literature and it comes from an old Chipokwan, is confirm that liang(梁) of Chipokwan's characteristic vanished. Pybyun is kwanmo which is associated with the military, comes from Jeolpung. The incision line was formed to make the corn shape, and this became the liang(梁). Buyongkwan is corolla adorned with lotus, and is highlighted with colored string of beads. Unlike other corollas, its gilt lotus was adorned with purple-yellow braids.

White and blue/white varieties of Torenia hybrida cv. Summerwave (SWB) were successfully obtained from the blue variety of by cosuppressing gene expression of two of the enzymes involved in anthocyanin biosynthesis; chalcone synthase (CHS) and dihydroflavonol 4-reductase (DFR). Such molecular brceding is the only precise and efficient way to widen the flower color variation of SWB due to its male and female sterility. Flower color and the degree of suppression varies depending on the transgenic lines. The dorsal and ventral petal lobes and corolla tube consistently lose anthocyanins prior to lateral petal lobes. A pink variety was also obtained by cosuppressing the flavonoid 3`5`-hydroxylase (F3`5`H) gene. Yellow torenia was obtained from T-33, an in-house cultivar that contained both carotenoids and anthocyanins, by blockage of anthocyanin biosynthesis with cosuppressing CHS or DFR genes.

자병취 (Saussurea chabyoungsanica Im..)에 대한 실체를 파악하기 위해 전반적인 형태학적 형질을 재검토하여 지역간 변이의 폭을 분석하였다. 태백산맥계에 속하는 만덕봉, 석병산, 석개재, 덕항산의 능선부 등 모두 석회암 지대에서 발견된 자병취와 북한에 자생하는 것으로 보고된 산골취의 외부형태에 대한 PCA분석 결과, 자병취 집단은 산골취 집단과 뚜렷이 구분되었고, 잎, 화관, 포엽의 형질이 주요 요인으로 나타났다. 또한 자병취의 지역별 외부형태의 분석결과, 석병산 지역의 자병취집단이 다른 지역의 자병취 집단과 구분되었으며 이는 환경구배현상에서 오는 차이가 반영된 것으로 생각된다.

Cowpea(Vigna unguiculata L. Walp) has excellent physical properties and texture of starch, so it is mainly used in various ways for songpyeon sediment, rice-cake paste, and porridge. To utilize it as various processed products such as songpyeon sediment and cowpea milk, 'Okhyun', which has green cotyledons and black seed coats and can be harvested by combine was developed. A cowpea variety 'Okhyun' was improved from the cross between IT145379 and IT208081 at the JARES in 2022. 'Okhyun' has an erect plant with an intermediate plant habit, a light purple-colored corolla, and heart-shaped leaflets. 'Okhyun' has green cotyledons and black seed coats, and has straight black brown pods when mature. The stem length of 'Okhyun' is 47cm, and the weight of 100-seed weight was 12.9g, which was lower than the control variety 'Okdang'(16.6g). 'Okhyun' contains 25.8mg/100g of anthocyanin, 279mg/100g of total polyphenols, and 335mg/100g of total flavonoids, respectively. The average yield of 'Okhyun' was 1.97ton per hectare, 11% higher than that of the control cultivar 'Okdang'. 'Okhyun'' does not require the installation of an espalier-net net, so it is possible to harvest with a combine. In addition, 'Okhyun' variety with green cotyledons and a black seed coat is expected to contribute to developing regional specialties and various processed products.

전북 변산에서 향유속의 신종인 변산향유(Elsholtzia byeonsanensis M. Kim)를 새로이 발견하여 기재 하였다. 분자생물학적인 결과는 변산향유가 근연종들과 구별되는 신종임을 지지해 주었다. 변산향유는 꽃이 한쪽 방향으로 밀생하는 수상화서이며 난형인 잎과 화관길이가 길어 꽃향유와 유사하다. 그러나 변산향유는 식물체는 작고 줄기는 자주색이며 잎은 혁질이고 윤기가 나며 엽병과 엽신 표면 및 화서의 포 표면에 털이 없고 바닷가 바위틈에 자라는 반면에, 꽃향유는 식물체는 크고 줄기는 녹색이며 잎은 초질이고 윤기가 없으며 엽병과 엽신 표면 및 화서의 포 표면에 털이 있고 숲 가장자리에서 자라는 점에서 두 종이 뚜렷하게 차이가 난다.

The present study was focused on the careful investigation of Glechoma longituba flowers collected from four populations in Korea to clarify their precise sexual systems. All floral characters of this taxon were examined by using a stereo microscopy. The nutlet size and production were compared between two distinct morphs (i.e., hermaphrodites and females), and pollen viability test of hermaphrodite and intermediate phenotype (i.e., individuals with a mixture of females and perfect flowers) was also observed by light microscopy (LM). All of the investigated floral characters of G. longituba are significantly different from one sexual morph to another. Hermaphroditic plants were larger than the female ones in corolla width and length, calyx length, filament length, anther length, and style length (all P < 0.0001, respectively). However, the nutlet width of the female plants was larger than those of the hermaphrodites (P = 0.013). Nutlet production of females was higher than hermaphrodites in Na-Ju population [H (Hermaphrodite): ca. 17.76%, F (Female): ca. 37.45%], but in Mun-San population was no significant difference between these sexual morphs (H: ca. 57.52%, F: ca. 53.16%). We have found significant differences between the fertile pollen grain of hermaphrodite and sterile pollen grain of intermediate phenotype based on pollen size and viability. The results of the present study suggest that compensation (flower size dimorphism, seed set, and pollen viability) is one of the main mechanisms in order to maintain female plants in gynodioecious G. longituba.
