본 연구는 관상적 가치가 뛰어난 한반도 자생식물 너도개미 자리[Minuartia laricina (L.) Mattf.]의 산업화를 위한 대량 번 식 기술을 개발하기 위해 수행되었다. 종자 번식 실험에서는 2023년 8월 16일 형태적으로 완전히 성숙한 종자를 채종하여 사용하였으며, 종자의 내부 형태를 관찰한 결과 배가 완전히 발달하여 미숙배로 인한 형태적 휴면(MD)은 없음을 확인하였 다. 또한, 종자를 증류수에 침지시켜 수분 흡수율을 조사한 결과 수분흡수 24시간 후 약 66%의 수분 흡수율을 보여 불투수성 종피에 의한 물리적 휴면(PY)도 없음을 확인하였다. 실온 (22±2℃)에서 후숙처리(Dry after-ripening)를 0, 4, 21주 실 시 후 각각 4, 10, 15, 20, 25, 30℃로 설정된 기내 발아 실험을 진행하였다. 실험의 결과, 후숙 4주 처리 후 20℃에 치상한 종자 의 발아율이 약 76%로 가장 높았다. 후숙 처리를 하지 않은 종자는 12주 내 어떠한 온도 조건에서도 발아하지 않아 생리 적 휴면(PD)으로 판단되었다. 삽목 번식 실험에서는 줄기삽목 (Stem-cutting) 방식으로 진행하였고, 루톤 분제 처리가 발근 에 미치는 영향을 조사하였다. 루톤 분제를 처리하지 않은 처리 구는 발근율과 생존율이 100%로 나타났으며, 루톤 분제가 처리 된 삽수는 이들보다 발근율과 생존율이 통계적으로 유의하게 낮았다. 따라서 너도개미자리 종자는 생리적 휴면 종자로 분류 되며, 4주간의 후숙 처리가 휴면 타파에 효과적인 것으로 확인 되었다. 또한, 너도개미자리 삽목 번식 시 별도의 발근 촉진제 처리가 필요하지 않음을 확인하였다.

Silene fissipetala Turcz., which is native to Continental China and Taiwan, was newly found in Chungcheongnam-do, Korea. S. fissipetala is similar to the related taxa S. antirrhina L., S. armeria L., and S. koreana Kom. in that it has glutinous zones. However, S. fissipetala is distinguished from the congeneric species by the presence of laciniate at the petals. The species grows on slopes and roadsides, suggesting that it is likely to have been introduced through the installation of green sites and road construction. A precise description, photographs, voucher specimens and a key to related taxa are provided.

Minuartia laricina (L.) Mattf. is a Korean native plant with high potential as a commercial flowering potted plant due to its compactness and long flowering duration. However, because this plant is a groundcover, it is susceptible to lodging and leggy growth. Therefore, this study investigated the effects of plant growth retardants (PGRs) on the inhibition of stem elongation and flowering characteristics of M. laricina. Commercial products, Trimmit, Cycocel, and B-Nine, were used for the exogenous PGR application of paclobutrazol (PBZ), chlormequat chloride (CCC), and daminozide (DMZ), respectively. Application concentrations were 50 and 100 mg·L-1 for PBZ; 100, 500, and 1,000 mg･L-1 for CCC; and 500, 1,000, and 2,000 mg·L-1 for DMZ. Paclobutrazol was the only PGR that inhibited stem elongation. The stem lengths of the plants treated with 50 or 100 mg·L-1 PBZ were 2.2 cm (13%) or 9.8 cm (57%) shorter, respectively, than those of the control. 50 mg·L-1 PBZ retarded stem growth effectively without negatively affecting flowering or other growth parameters, whereas 100 mg·L-1 PBZ caused excessive dwarfing and significantly reduced flowering by 59%. CCC and DMZ applications were ineffective for growth control. Flowering time was accelerated with most PGRs, except for 2,000 mg·L-1 DMZ, reducing the time to flowering by 2–8 days. These results indicate that the stem growth of M. laricina was successfully inhibited with PBZ but not with CCC or DMZ. Thus, we concluded that a single application of 50 mg·L-1 PBZ or similar treatment is effective in miniaturizing M. laricina without causing harm to its growth or aesthetic value, such as the flower number. Additionally, because CCC and DMZ are not persistent in the growing medium, testing multiple application times for these PGRs is crucial.

For the purpose of developing Korean Herbalogy with the plants of Caryophllcceae which grow wild and is planted in Korea, the these and writings on herbalogy, from literature of successive generation, have been thoroughly investigative and the results obtained were as follows: 1. There were totaled to 20 genera and 124 species in Korea and among them midical plants are 11 genera, 30 species, some 24% in total. 2. According to the oriental names which can be used for medical purpose, the medical plantss belonging to the Caryphllaceae family were classified as Herba 11, Radix 7, Foilum 2, Semen, Flos, Rhizoma 1 each 3. According to sum of 124 species in Caryophllaceae family, they were classified into Cerastium genera 18, Dianthus gemera 16, Pseudos tellaria genera, Lychnis genera, Stellaria genera 12 each, Melandry um genera 11, Silene genera 10, Minuaria genera 8, Gypsophila genera, Sagina genera 5 each, Arenaria genera, Cucubalus genera 3 each, Spergual genera, Vaccaria genera 2 each, Agorostema genera, Amnodenia genara, Moehringia genera, Myosoton genera, Honkenya genera 1 each. Thus it was noticed that Cerastium genera was main kind 4. According to the number of species of the orgin plants about each chinese materia medicals, they were classified into HERBA DIANTHI 4, RADIX PSEUDOSTELLARIAE 3, SEMEN VACCARIAE 5, RADIX GYPSOPHILAE 4. 5. According to the properties and principal curative action, they were classfied into drugs for treating febrifugal and removing heat from blood, Diuretocs 6 each, Drugs for treating febrifugal and detoxicant 2, Drugs for invigorating blood, circuration and eliminating blood stasis 3, tonics 1, easing joint movement 1, stimulation of lactation 44. 6. According to nature and flavour of medical plants, they were classified into warmth, heat; each 3, cold, cool; 11each, balance 3 and unidentifird 2. Thus it was noticed that cold and cool is the main in nature and flavour of medical plants. 7. Toxic drugs were none. From this results, It was revealed that the plants for medical purpose in Caryophllaceae was 24% of the whole, in which Herba was mostly abundunt. It is considered that may expriements and clinical approches must be continued to use Caryophllaceae plants widely.
