  • This study was conducted to investigate the effect of age of transplants, propagated by cutting, of two cut rose (Rosa hybrida Hort.) cultivars on their subsequent growth and yield in an effort to develop an efficient cutting propagation method for domestic rose cultivars. Two cultivars used in this study were a standard type 'Pink Aurora' and a spray type 'Yellow King'. Cuttings were prepared as single node cuttings each with a five-leaflet leaf and were stuck in rockwool cubes ($5cm{\times}5cm{\times}5cm$, UR, Korea) at two different dates. Cuttings rooted for either 30 (stuck on Jan. 20, 2009) or 48 days (stuck on Jan. 2, 2009) were transplanted into a rockwool slabs ($10cm{\times}15cm{\times}100cm$, UR, Korea) on the same date, 18 Feb. 2009. Plant growth and cut flower quality were investigated for two successive harvests during the period of Jan. to July in 2009. In both cultivars, 48 days old plants showed some growth of the shoot and root before transplanting. However, in the case of 30 days old plants before transplanting no noticeable growth of the shoot and root was obserable in 'Pink Aurora', while only shoot growth, but not root growth to the bottom of the rooting medium, was observed in 'Yellow King'. This suggested cultivar-specific responses that in this experiment a spray type 'Yellow King' showed greater growth rate during the rooting stage than a standard type 'Pink Aurora'. In the measurement of growth and cut flower yield after transplanting, the 48 days old standard type 'Pink Aurora' produced greater number of cut flowers per plant than 30 days old plants, whereas their mean stem fresh weight was recorded smaller than that of the 30 days old plants. For 'Yellow King', 30 days old plants showed greater stem length, flower width, number of five-leaflet leaves per stem, stem fresh weight, and number of cut flowers per plant than 48 days old plants. Therefore, growth and yield were significantly affected by cultivar and age of the rooted cutting, and additional research is needed on the effect of age of rooted cuttings in more cultivars.

  • Pink rot of Palm was occurred at Yeuju area in 2001 and 2003. Infected plants showed rotting at the leaf-stock bases and killing of the terminal bud. The first symptoms are dark brown necrotic areas on the stem. Bases of infected frond may be covered with pink spores and the spots produced oozing gum pockets. Oozing lesions occur on the stems, and leaves turn brown and droop. The causal agent were isolated from salmon-pink spores sporulating on the leaf sheaths and necrotic stem tissues. Pathogen were isolated from freshly infected tissues were identified as Gliocladium vermoseni based on mycological characteristics. Fungus were grown plenty on PDA culture. Temperature for mycelial grown was tested at 5 to $40^{\circ}C$ and optimal temperature was $25^{\circ}C$ and was not nearly grew at temperature above $35^{\circ}C$. Artificial pathogenicity were tested on 9 species of Palm family in the wound inoculation and symptoms showed similar to those observed in the field. This is the first report on pink rot of palm in Korea.

  • In 2012, a pink mold rot was observed on apple (Malus pumila var. dulcissima Koidz.) at the Wholesale Market for Agricultural Products, Jinju, Korea. The first symptom of pink mold rot on apple fruit is a water-soaked appearance of the affected tissue and surface fruit formed pink mold rot, then became brown and produced a mass of powdery pink conidia spores. Colony was fast growing colonies, pinksh, zonate in diurnal rhythm, powdery from conidia. Optimum temperature for mycelial growth was $25^{\circ}C$. Conidia were hyaline, smooth, two-celled, thick-walled conidia with truncate bases, ellipsoidal to pyriform, and characteristically held together zig-zag chains and $12-26{\times}8-12{\mu}m$ in size. Conidiophore was erect, colorless, unbranched, and $4-5{\mu}m$ wide. On the basis of mycological characteristics, pathogenicity test, and molecular identification with the ITS region, the causal fungus was identified as Trichothecium roseum (Pers.) Link ex Gray.

  • Background: Breast and cervical cancers are the most common causes of cancer mortality among women in India, but actually they are largely preventable diseases. Although early detection is the only way to reduce morbidity and mortality, there are limited data on breast and cervical cancer knowledge, safe practices and attitudes of teachers in India. The purpose of this study is to assess the level of awareness and impact of awareness programs in adoption of safe practices in prevention and early detection. Materials and Methods: This assessment was part of a pink chain campaign on cancer awareness. During cancer awareness events in 2011 at various women colleges in different parts in India, a pre-test related to cervical cancer and breast cancer was followed by an awareness program. Post-tests using the same questionnaire were conducted at the end of the interactive session, at 6 months and 1 year. Results: A total of 156 out of 182 teachers participated in the study (overall response rate was 85.7 %). Mean age of the study population was 42.4 years (range- 28-59 yrs). There was a significant increase in level of knowledge regarding cervical and breast cancer at 6 months and this was sustained at 1 year. Adoption of breast self examination (BSE) was significantly more frequent in comparison to CBE, mammography and the Pap test. Magazines and newspapers were sources for knowledge regarding screening tests for breast cancer in more than 60% of teachers where as more than 75% were educated by doctors regarding the Pap test. Post awareness at 6 months and 1 year, there was a significant change in alcohol and smoking habits. Major reasons for not doing screening test were found to be ignorance (50%), lethargic attitude (44.8%) and lack of time (34.6%). Conclusions: Level of knowledge of breast cancer risk factors, symptoms and screening methods was high as compared to cervical cancer. There was a significant increase in level of knowledge regarding cervical and breast cancer at 6 months and this was sustained at 1 year. Adoption of BSE was significantly greater in comparison to CBE, mammography and the Pap test. To inculcate safe practices in lifestyle of people, awareness programmes such as pink chain campaign should be conducted more widely and frequently.

  • Pink rot of potato (Solanum tuberosum L.) occurred at Pyeongchang in Gangwon and at Bosung in Junnam province since 1999. The disease incidence in the surveyed areas was about 5% of harvested potatoes in 2002. Affected tubers showed a dull brown appearance and the lenticels and eyes on tubers turned dark brown. The cut surface of the diseased tuber colored faint pink and the entire surface of the diseased tuber becomes deep salmon pink within 30 min. The pathogen isolated from the diseased tubers was identified as Phytophthora erythroseptica based on morphological and cultural characteristics. Mycelial mat was fairly fluffy, rosette or stellate patterns and rounded or angular hyphal swellings were farmed in water, Temperature for mycelial growth was ranged from 5 to 3$0^{\circ}C$ and optimal temperature was $25^{\circ}C$. Non-papillate sporangia were persistent on stalk and ellipsoid, ovoid, obpyriform or distorted in shape, often with a constriction distal in the middle. Size of sporangia was 41.3~69.6$\times$26.8~47.4 (av, 55.5$\times$37.1) ${\mu}{\textrm}{m}$. Sexuality of Phytophthora erythroseptica was homothallic. Oogonia were 30~46 ${\mu}{\textrm}{m}$ in diameter and oospores were 28~35 ${\mu}{\textrm}{m}$ in diameter, Elongated or cyclindrical antheridia were all amphigynous. This is the first report on potato pink rot caused by Phytophthora erythroseptica in Korea.

  • A FA intersectional hybrid lily cultivar 'Cherry Pink' was developed in 2006 at National Institute of Horticultural and Herbal Science (NIHHS), Rural Development Administration (RDA) Korea. The cross and immature embryo rescue was conducted between female parents Lilium FA hybrid 'Supia' and male parents L. Asiatic hybrid 'A94-9' by cut style pollination method (CSM) at Suwon in 1999. The first selection was done and was tentatively named as 'FA01-17' in 2001. After in vitro multiplication, bulbing production of 'FA01-17' line, growth and flowering characteristic tests were conducted from 2002 to 2005. The evaluation of characteristics and consumer preferences were surveyed at a lily flower show of NIHHS at Taean in 2006. 'Cherry Pink' flowered in the middle of June and grew more than 120 cm stem in length. Flowers bloomed facing upward, a little spotted in petals and deep pink (RHS, RP27D). The pollen of 'Cherry Pink' was sterile. Year-round flowering can be done by storing the bulb under $-1.5^{\circ}C$ conditions. It was needed to control Botrytis disease in wet season.
