The objective of the present study was to review the current research about the outcomes of horticultural activity interventions in order to determine research trends and analyze the characteristics of horticultural activity interventions. We reviewed the literature using search engines such as the Web of Science, Proquest Dissertation and Theses, Academic Search Premier, Research Information sharing Service, and Korean National Assembly Digital Library to locate journal articles that include relevant search terms (e.g., gardening activity, gardening program, allotment garden, urban agriculture, horticultural therapy, and horticultural activity). We initially identified 14,414 journal articles that were published before April 2014 and selected 509 of the papers for review. We found that studies investigating treating children and adults 8 to 64 years old were the most common, and horticultural activities such as gardening outdoors, planting indoors, making crafts with live plants, arranging flowers, making crafts with artificial or pressed flowers, and other activities were usually combined. Short/medium term (11 to 20 sessions) horticultural activity programs were the most frequent, and most interventions were of medium duration (> 60 min to 120 min). Most of the studies focused on the psychological or emotional effects of horticultural intervention, such as its effects on emotional intelligence, self-esteem, stress, and depression. Further studies are needed to analyze the research methodology, specific outcomes, and strengths or weaknesses of studies investigating horticultural activity interventions.

In April 2014, seedlings of Fallopia multiflora showing wilt symptom were first found at a greenhouse in Punggi-eup, Yeongju-si, Korea. A Fusarium-like fungus was isolated from the wilted plant and it was identified as Fusarium oxysporum based on morphological characteristics and nucleotide sequence data of translation elongation factor 1-${\alpha}$. The fungus isolated from the diseased plant was revealed to be pathogenic to the host plant through pathogenicity tests, and the reisolation of the pathogen confirmed Koch's postulates. This is the first report of Fusarium wilt occurring on Fallopia multiflora in the world.

2005년 전남 나주와 광주의 멜론 재배포장에서 잎맥을 따라 갈색으로 변색되면서 시드는 증상이 관찰되었고, 과실 표면에는 점무늬의 수침상이 형성되며 과실 내부는 갈색으로 썩는 증상이 관찰되었다. 잎과 과실의 병반부로부터 2개의 세균을 분리하여 생리생화학적 실험, 유전적 실험 및 병원성 실험 결과 Acidovorax avenae subsp. citrulli로 동정되었다. 이 보고는 국내에서 최초이며, 이 병을 멜론 과실썩음병으로 명명할 것을 제안한다.

PDA 배지상에서 작은뿌리파리 유충과 성충은 토양 전염성 병원균인 Fusarium oxysporum을 전반하였으며, 성충에 비해 유충의 전반이 높았다. 작은뿌리파리 유충은 F. oxysporum 균을 섭식하여 전반하였으며, 성충은 몸체에 균을 묻혀 전반하였다. 형광발현 형질전환 F. oxysporum 균을 제작하여 작은뿌리파리 유충에 먹인 결과 균은 소화관을 따라 분포하였다.

Grapevine leafroll-associated 3 virus (GLRaV-3) and Grapevine fanleaf virus (GFLV) are important viral diseases of grapevine in the world. In this study, the most reliable woody indicator plants were selected for virus indexing. Two grapevines, LN33 (Couderc 1613x vitis berlandieri) and Vitis riparia Gloire, were selected for CLRaV-3 and CFLV graft indexing, respectively. The specific characteristics of Closterovirus isolated from grapevines cultivated in Korea were identified. filamentous virus-like particles only existed in the phloem parenchyma cell. In particular, the vesiculation of mitochondria was observed. This mitochondrial vesicu-lation was considered to be one of the most reliable cytopathic features of Closterovirus. During observation of GFLV-infected Chenopodium quinoa sections, virus-like particles arranged consistently were found forming several layers in cytoplasm. Moreover, virus-like particles in tubules were observed and were associated with plasmodesmata in cytoplasm. This is the first report on cytopathological characteristics of Closterovirus and Nepovirus identified from grapevines in Korea.

Chinese yam necrotic mosaic virus (CYNMV) is one of the most widespread viruses in Chinese yam (Dioscorea opposita Thunb.) and causes serious yield losses. Currently, genetic information of CYNMV is very restricted and complete genome sequences of only two isolates (one from Japan and another from China) have been reported. In this study, we determined complete genome sequence of the CYNMV isolate AD collected from Andong, Korea. Genetic analysis of the polyprotein amino acid sequence revealed that the Korean isolate AD has high similarity with the Japanese isolate PES3 (97%) but relatively low similarity with the Chinese isolate FX1 (78%). Phylogenetic analysis using the CYNMV 3' proximal nucleotide sequences harboring the coat protein and 3' untranslated region further supported genetic relationship among the CYNMV isolates. Based on comparative analysis of the CYNMV genome sequences determined in this study and other previous studies, we generated molecular detection primers that are highly specific and efficient for CYNMV diagnosis.

Introduction of vegetatively propagated Petunia hybrids since 1992 led to increasing virus infections of propagation material. Petunia hybrid 'Surfinia' cultivated for pot-plant showed yellowing symptom along with stunt. Flowers were smaller in size and showed color-break symptom. Tobacco mosaic virus(TMV-pet) was isolated from the diseased petunia. Healthy petunia plants inoculated with TMV-pet induced mottle on leaves and color-break on flowers, and plants were stunted. Nucleotide sequences of coat protein gene amplified from RNA prepared from Nicotiana tabacum cv. Samsun infected with TMV-pet were determined(GenBank accession no. DQ981481). It showed 99.0% nucleotide sequence homology with TMV-potato3-2(GenBank accession no. AF318215) isolated from potato showing yellow mosaic and stunt symptom, and with a TMV Korean strain(GenBank accession no. X68110). This is the first reported observation of TMV from vegetatively propagated petunia in Korea.

In order to actively apply horticultural therapy to vocational education base schools, this study applied the learning theories based on behaviorism, cognitivism, and constructivism to improve the vocational skills of high school students with intellectual disabilities. The horticultural therapy program was carried out in total 12 sessions with three groups composed of 20 students each: 20 in the control group, 20 in the experimental group with a normal horticultural program, and 20 in the experimental group with a horticultural therapy program which applied the learning theories based on behaviorism, cognitivism, and constructivism. The results were analyzed with SPSS 12.0 using the Interpersonal Negotiation Strategies evaluation tool. The study found that in terms of interpersonal relationship, there was no significant difference between the pre and post tests within each group. However, in the post tests among the three groups, there was no significant difference between control group and experimental group with normal horticultural program (p=.82), but there was a significant difference between the control group and experimental group with the horticultural therapy program applying the learning theories based on behaviorism, cognitivism (p=.03). This proved that the horticultural therapy program applying the learning theories based on behaviorism, cognitivism is effective for improving interpersonal relationship. Ultimately the program is expected to be continuously, and systematically improved and applied as a learning method contributing to developing the basic vocational skills of persons with intellectual disabilities.
